Full head bleaching and tone.


Welcome to BACK2MYROOTS B2MR regular postings of fresh new topic’s    http://www.back2myroots.co.uk/

                                lifting agent bleach powder:

Hair Lighteners:  Powder Bleach, Oil or Gel.

Before Embarking On lightening hair one has to understand the chemistry of the product and how the process works. Hair Lighteners  and Decolourizers come in many forms and are designed to remove Colour from the hair. Basically they are Alkalisers.

How do these work:

They are products that supply Sufficient Alkali to destabilise hydrogen peroxide, when the two products are mixed together the Hydrogen attacks the pigment in the hair and Lightens it. Hydrogen Peroxide is Stabilised in a bottle with a low Ph around {3.00-3.5} adding the lightener be it {powder or liquid-gel} brings the mixture up to a Ph of around 9.0 triggering oxygen release.

Types of Lighteners:

Bleach powder Lighteners are for the most part Stronger and faster acting. Generally used for off scalp Lightening application. { always do skin and stand test} Lifting ability is dictated by strength of hydrogen peroxide and timing formulation. 

Lotions Oil -Gel: 

These have a smoother consistency and are formulated to protect the skin/scalp during the lightening process.Most powder bleaches are not recommended for direct scalp application they may cause reaction an for burning or irritation {Be advised that adding heat/ dry or steam will change the way these products react: powder bleach can dry out under heat!

Ingredients:

The chemical Structure of lighteners are Ammonia.Ammonia hydroxide,Magnesium silicate,and sodium. quite the mix all lighteners have to be mixed with hydrogen peroxide. { Be advised hair that has been coloured with any kind of metallic rinse, colour or stain, will create a heat reaction that can cause burning so do your home work!}

When to use:

A key tool for colour correction, but generally they are used when other products available cannot give the desired degree of Lightening.{ Remember High lift Tint will only give max 4levels of lift when mixed with 40vol Peroxide} 

Uses: High-lights, pastel blonde look when hair is strongly or pigmented  darker shades.

Mixing:  Always follow Instructions on each given product! for lotions/gel /oil double amount of Hydrogen peroxide is often called for. lotions and lighteners/Booster powders must always be mixed in Sequence,{note: mixed out of sequence can result in uneven lift!}

Stages of Lightening:

When lifting /lightening hair it goes through what is known as the 7 stages of lift. It has no limits it can remove all pigment from the hair.

Remember the Colour wheel: {you can see shades in the outer} wheel      

The stages are as follows.

Red-Brown. Red. Red-orange. orange-yellow. yellow -orange.

yellow.pale yellow.

The first colour is always the stronger shade!

The deeper the base shade the more stages of lift required its a journey don’t rush it.

Advantages:

*lightens hair.

*Can be used for colour Correction.

*Adds Texture.

Disadvantages:

*re-growth needs to be maintained.

*Can damage hair.

*Can cause Skin irritation.

* Hair should be protected form Uv -sun light.

Summing Up:

A very useful Tool for us to have but should be respected and understood, I advocate the best path is the one with the least chemistry possible.

Lets re touch on bleach bath/ Cocktail:

What is a bleach bath used for? It is a tool that we have at our disposal to gently lift unwanted pigment from the hair. It is classed as the first line of attack when doing Colour correction:

One would use this formula to lift pigment {note it does not remove pigment} prior to toning or adding your fun colour.

As i have stated before if you are going bright red you don”t need to remove all pigment yellow or orange is fine! if you want true blue you have to get rid of the yellow toning would do this!

Formula for Cocktail. 1/2 OZ Clarifying shampoo 1oz water. 1oz 20 vol peroxide or developer. 1oz/or scoop of bleach.

Wet hair wear Gloves apply and work into your hair for 10 to 15 mins. wash out really well if you don’t get enough lift don’t give up mix up second batch re apply. don’t rinse out re-apply the water stops the action. Remember lift is all about timing;and observation.

It is a miss conception in thinking that 40vol is stronger than 20 vol not true its just long lasting in how long it lifts for {How long the hydrogen gas re acts the oxygen}.

What is toner

Toner is basically a tube or bottle of pigment little or no peroxide is required.Designed to neutralise the unwanted pigment exposed in the lifting process.Deposit only no lift when using a toner in some cases low volume of peroxide may be required to activate the colour molecule. When toning one should always stay with it as it continues it’s neutralisation and despot until rinsed off.The should be considered as a from of colour correction.

                                    High lift Blonde series:

All these shades are toners:

B indicates Beige = Green Orange Base will neutralise pale yellow.

G indicates Gold =yellow orange base for warmth and tone.

V indicates  Violet= red blue base with neutralise  yellow or yellow pale orange

A indicates   Ash =blue  yellow green  will neutralise  Orange orange yellow

Above classic case for toning in my view way to yellow gold. What might you use here?

To beige this look out on would use a violet toner worked in for a few minutes it would restore balance getting rid of unwanted warmth .again there is no exact time stay with it do not leave alone for any period. you may end up with  sludge tone!!!

I found a link for this skin test sight happy to share as i think skin testing is so important.

http://www.trichocare.co.uk/

                                                         Quote from sight:

Colourstart is a unique patch test used by hairdressers as a skin allergy test. These tests help the hairdresser to check if clients are likely to have a problem with hair dye. The alternative is often unpopular and impractical for clients. Colourstart is used on clients who do not have time to visit the salon 48 hours before every application. It is used on clients who do not want hair dye left open on their skin. Colour start is one of the most important advancements in professional hairdressing. It helps to improve client satisfaction and safety in the salon. Due to its benefits and ease of use, Colourstart is rapidly becoming an industry standard.

With a little patient a good consultation and some formulation planning a great shade of bleached an droned hair can be achieved without undue stress and or damage.

Blonde issues and thoughts


Back2myroots : A place to share thoughts and grow idea’s. B2MR

Time to move on lets look at Blonde hair colouring issues :

Lets start with a case study of Highlights and low lights  [lift and deposit] This in it self can create many issues both from a technical stance and from a client stylist relationship point of view. Many years of experience have shown me that when a client is unhappy with her blonde hair the maintenance required and yes the cost things can start to go down hill on the communication front.

Let me introduce to you our client Emily and our Stylist Ted.

Emily has long hair and is a natural level 6 [mouse/rat] she loves being blonde but over time feels that she has lost the highlighted look that she so loved and that the maintenance and cost is starting to become an issue an condition is starting to be a worry!

The consultation: Ted sit down with Emily and off the bat say’s you have no idea how many young women like your self i have this conversation with. Just how common place this issue is. But don’t worry it’s fixable today and maintainable for the future. Oh really says Emily that is so good to hear I was worried that was future was turning very dark! Does this look ring any bells with you as a stylist? Back with. Ted he begins to explain that over time sadly the highlighted look can get lost it’s a mixture of a few factors, some responsibility for this falls with you the client some with us stylist’s. Yes he say’s not perfect just trying to be! They both laugh another good sign.

Firstly says Ted. I agree that Blonde works well for you you have the perfect natural base shade the problem is over time you and your stylist have allowed your hair to get to blonde. It has lost any any depth and tone and just become a bleached highlighted look.You see say’s Ted the lighter we allow you hair to the quicker the roots will appear. It’s not intentionally done it creeps up. But it’s my opinion that we as stylist’s owe it you as our clients to be honest and some times draw the line when it comes to letting you go blonder and blonder!  Ted goes on to say. We have to explain to you what we think is best.You may not always listen or like what you hear, but hey you are paying me for my professional advise as well as my skill. Wow say’s Emily that’s a first no one have ever told me all that.

Well here is what we are going to do.

Firstly only Highlight the top half of your head and this will be some highlights to keep you blonde and we will re introduce two other shades.One shade at your natural level and a nice Beige to pull it all together. we will then fill in all the under section of your hair taking it back to your own colour. Ted explains that the darker under section will look more natural and look way better when Emily put her hair up. Emily says sounds great lets do it!

A Formulation for this: 

Roots 1oz [30 grams ] Bleach powder with 2oz [60 grams] 2o Volume peroxide.This will be used on the weaved highlights but only on the roots and with a slight over lap to prevent banding.

Second formulation is two mixtures:

8N with 30 Volume. Why more lift but the pigmentation of the 8N will control the yellow orange we will expose making it a nice beige.1oz 8N  11/2 oz 30 volume peroxide roots only Mid lengths and ends 8B Demi lotion formulation mixing ration 1oz 8B to 2oz Demi lotion developer for mid lengths and ends so we are in effect lifting and depositing at the same time.[ mark your bowls so you don’t mix them up] Final Formulation 6B as a Demi formulation  for deposit only this is also the shade we will run through the under section again no lift just deposit. 2oz 6B 4oz Demi lotion developer enough to do both the low light and go straight in to the under section application. Making full use of your time and not wasting product.

Once all the formulations mixed up Ted sets to work. Oh says Emily you don’t use foil no say’s Ted I like these waxed papers they stay much closer to the roots they don’t slip less pain when i take them out! Oh i like the sound of that says Emily, it’s always painful.Not today says Ted! Once all done the process time will be dependent on the last few Highlights we have put in says Ted. But don’t worry I stared at the front so they will be a little blonder and we will not lift the crown as much. the Darker shade is none progressive so stops once it reached desired colour. So all good be patient no heat but will not be to long. they wait the out come.

Ted checks the progress a couple of times and after 30 Minutes it ready to come off he takes all the papers out and then rinses very quickly holding the highlighted hair away from the darker underneath once it’s all rinsed of colour it’s a normal shampoo and conditioning process.

Remember those dark roots that line of demarcation? All gone and blended in. Now we have a very natural looking Blonde with highlights and low lights to tone it down and control the root issue. Emily say’s she is so happy it’s the best it’s been is such a long time. Ted says leave it as long as possible our goal is to get you coming back every three months. Why are not all hairdresser like you most say 6 weeks are says Ted. Here is the deal you like your hair you tell your friends you and your friends and their friends keep me busy  to the point that i can only see you every three months!Oh says Emily i see  me and my friends keep you busy I hope so says Ted.

Oh and as for the under section check this out! As a form of re colouring and depositing pigment I cannot express enough what a wonderful gentle formulation a Demi application is. It will give even depth and tone without the need for and lift. Its a satin finish that loos so natural. give it a try. I think that as stylists we have so many options choices of technique and products at our disposal, we are truly very lucky. Oh and having great clients helps. We have so many issues that can arise when working with our clients to create that natural blonde look to maintain it.The key is communication and honesty. Our clients will always push to be that little bit blonder it’s up to us as professional to some times to pull the reins in to prevent future issues.

What are these issues, They normal arise from over processing, poor condition, colour fading. longevity of colour lasting, leading to cost issues. Always keep your client on track be open about maintenance issues cost of up keep. Remember your the professional your in control.

As promised some extra views and thoughts on some Blonde hair issues 

I look around me when out in public and see so many cases of over processed hair,  badly done highlights and streaks examples of this can come in many forms. Streaks and Highlights that look bright at the roots but fade away in the mid lengths and ends. Streaks highlights low lights that have been done with bleach pre lightening and then colour deposited on top to create pigment and tone. In so many cases this colour fades away oh so quickly, leaving bright yellow blonde roots and faded flat colour on the rest of the hair shaft caused by over processing over lifting lack of porosity in the hair.

Patchy streaks dull blonde caused by using wrong shade as a toner. An example of this yellow blonde lift from bleach decolourizer, then  selecting ash as toner a misconception that ash is the correct shade yellow and blue make for a green hue! Violet would be a correct choice. All hair colouring is addressing issues around colour balancing replacing pigments that the hair is lacking. Everything stems from the three primary colours that make up hair colour Red, Blue, Yellow. We then have secondary colour and so on using ones colour wheel is key to correct colour balancing toning and correction a re-balancing or replacing missing pigments.

When colouring hair. Having the knowledge and an understanding of the process lift, deposit, neutralizing and utilizing underlying pigment. The chemistry and pigments you have exposed through the lifting process for colouring is all about lift and deposit not just choose a colour and put in on any given head. Most Colour brands will lift a maximum of 4 levels so if you are lifting from a level 6 to 10 you will not get to the target colour with 40 volume peroxide and your colour will always be to gold or yellow! Why? underlying pigment.When considering the above lift from level 6 to 10 think about where 6 lives on a colour wheel then think about level 10 then consider all the under pigment you will expose as you lift through these levels this will help you decide if your Target is possible.

As soon as you lift level 6 one level you expose red orange, then orange then yellow orange then yellow and last of all pale yellow so four levels of lift will leave you with a yellow base. If your trying for a natural blonde it will be to yellow so toning what do we choose? Ash ? Violet? Beige?

                             blonde high lights low lights

Lets go back to level 6 to 10 and 40 volume peroxide this degree of lift is not possible why because you have to lift through level 6 then 7,8,9 this is your four level so 10 is not attainable with permanent colour unless you pre-lighten with Bleach decolourizer,This process warrants some time so you don’t end up with bright over lifted roots! Before we embark on this we have to consider the head we are working on is    it pre-coloured? can we lift out that colour? again what pigment will we expose? what condition is the hair in how porous is it? will it hold colour? strand test it  when wet will it stretch? does it float or sink in water? if it does not float it’s over processed and will not hold colour strongly recommend not to pre lighten this hair.

Consultation look touch question. but remember that most people tend to be rather dishonest about their colour history weather it be home exploration or professional also some hair dresser tell clients that colours are semi permanent even when they do both lift and deposit! why because they don’t take the time to understand the chemistry of the product they are using also many of the companies miss lead stylist in the way their colours work!

Herbal, Ammonia free, no lift, no peroxide. ask, ask, ask, then ask again!! get all the information you can be the best you can understand the chemistry of the colour and the the pigment available to you in any given shade.

Will the Natural series have enough pigment to hold a natural level when using 20 volume peroxide or will it be to warm ? Questions you have to ask your self and consider.  The above is a perfect balance of high lights and low lights a very natural multi-tonal look.

Well we are having a very varied day and lets be honest the time needed to deal with all these issues is quite considerable. But with all the knowledge we had and all the new knowledge we have we should be coping very well.

enjoy Mike B2MR

A hair colour disaster and fix.


Back2myroots: A place to share thoughts and grow idea’s. B2MR

Here we are looking at a colour correction scenario:

*What is the best way to share with you? To look at real issues!

*How do we put all of this new found information into practice. By solving issues.

*How do we apply this knowledge in a practical sense? Does it really work. By thinking through the issue panning!

By sharing some real life salon colour stories with you.

We can cover many of the issues that you can expect and do come across daily with your clients. [ please note names of clients and stylists changed events situation are based on real events] Permission to publish and relay these cases have been sought and given.

In all my years as an educator I have been fortunate and have had the pleasure to be invited into many salons. These are some cases that arose whilst spending time in any given salon or in my own career as a stylist none are made up. In most cases of salon colour mistakes the error are caused buy the stylist making poor choice for applications.

Lets get on our colour case:

Alison came into the salon. She had long hair mid way down her back. Her goal going lighter maybe some nice caramel toffee low lights. She had solid colour built up with a number of applications over number of visits.

Sounds easy Right?

Firstly Alison needed to have a consultation with Paul her stylist. Discuss her goal and optimum colour target. Both need to be honest about past colour history. Her natural level would be around level 5. The colour that had been used for previous colours was a rich dark brown around level 4. In this instance Demi colour formulation for tone on tone deposit only! Long term build up would be a issues. This came out in the consultation process.

Lots of pigment would have built up over time and application this needs to be lifted and  underlying pigment exposed. With the build up of darker shade in the mid lengths and ends  the lifting process would take some time. Staring from the ends and working towards the scalp. It was discussed that the root will lift Blonde very quickly. So the approach would be to use a bleach formulation with be applied to the ends and mid section first. The roots would be left until a desired level was attained as they would lift very quickly. The Prolonged use of the dark brown colour over a long term would cause build up of colour mid length’s and ends.

Alison should have been given a strand test. She did ask for strand test Paul her stylist said’  That will not be required [first mistake and short cut] . Is this that hard?  Remove a small amount of hair from the nape area and have it coloured or lifted prior to full head application. It’s lazy .It’s un professional it’s taking short cuts!

This would have required especially as. Bleaching out old pigment and applying the formulation from the ends up through mid length and finally to the root would create colour bars of pigment also taking into consideration the weave of the highlights.Once lifted evenly to a desired workable tone. Apply toner to even out to desired shade and tone.

Why so work end sot roots you may ask? The ends will lift the slowest and will dictate the end result the mid lengths although coloured less still holding lots pigment. This pigment exposed in the lifting process will tend to be very warm copper or orange. This will need toning to neutralise the unwanted warmth.

After her consultation with Paul. Alison is ready to get her new caramel low lights done

                    pre having low lights done coloured level 4

Above: Is picture of the hair prior to the colouring.

As stated this colour was always done as deposit only. No lift when going tone on tone or darker unless you want to add or increase warmth you do not need lifting levels of hydrogen peroxide. Any build up of colour is just layers of dark pigment. As stated a rich dark brown it matches her skin colour and hazel eyes. Many salons over book they don’t allow the time or put in the effort to do a job correctly.When things go wrong they may make excuses about the product, may pretend it looks great. It’s how it was supposed to look. But it’s the client who has to be excited love this new look get what she wants and requested.

They have trusted us.Sat in the chair patiently.They asked all the right questions. They gave us time to decide on the best course of action to take. Having supposedly considered all options.

                                     After low lights

Why does this happen? What went wrong? what do you see? what do you think? Why do you think it went wrong! Paul had done the consultation asked all the right questions. But took short cuts starting with refusing the need for a strand test. By not thinking the process through working in from the ends to the mid length finally to the roots. He rushed and failed. He did not allow enough time for the different levels of lift to be addressed.

Remember the request was for low lights. Caramel toffee. Remember suggested strand test. Consultation .Remember if he had lifted the hair from ends in. Allowing for the fact that the mid lengths may throw orange and roots would lift really quickly. All would have been well, time consuming but it’s never race!

Lets review. Firstly I was shocked. Sad. Appalled by this poor quality job. Caused by taking short cuts with very little thought given to the process or out come! A rush job. Firstly the the blonde on the roots to eye level really does not work for her. It sucks the colour from her skin and is just a nothing dull boring shade of blonde.

The mid lengths did not lift as much as required or expected they formed a colour bar. A very bright copper orange as the dark pigment lifted out. Finally the mid lengths into the ends lifted such a little that they still look solid and dark very little lift. There is no way by just applying toner this can or could be fixed.  It was doomed to fail. This was caused by some one being lazy, applying bleach de-colouriser roots to ends and just hoping that it may all lift evenly or at least enough to colour balance it! Hoping that whatever pigments exposed could be evened out with a toner. In doing this the tones made the blonde dull had little effect on the orange and well the ends ! Hum Hoping is not good enough!! use the tools we have consult charts .work within the rules.

The strand test should have been carried out in advance of the appointment. The strand test shown and discussed with client then the process carried out correctly with a great out come. Why oh why do we allow this to happen? Why do we let our selves down . Is it lack of time?  Is it Easy money? well hardly if now you have to fix and re do! Lack caring. Paul let his client down. He let the salon down. He let himself down! Oh how does this look to the staff what message does it send Paul is the owner!!

Can this be fixed: Yes or course it can. As stylist’s when things go wrong we have to drop any attitude and put right a wrong.even more so when it in no way the fault of the client,who now has to return find more time and we have to regain that trust! drop the ego! 

To review:  The attempt at lifting evenly from roots to ends was a failure. Leaving over lightened roots mid lengths with a real orange hue and very little lift on the ends. The desired effect was for toffee caramel low lights.

                               poor colour job before shot

The picture was provided client Alison. But as you can see it really was a poor job. When seeing this many thing came to mind apart from the poor job. First though was how the blonde just did not work with either skin tone or eye colour.

My suggestion would be get rid of it ASAP! Go back to being a rich dark healthy chocolate brown.

How would you do this, well it certainly would not require any more lift just a re build of the pigment base in the over lightened section then colour balance. My suggestion would be to fill the over lightened section with a Demi formulation of either 7G or 7GC predominantly gold but with enough copper to balance with with warmth of the mid section. only apply to overly lifted area. leave for around 10 Minutes or[ follow your product directions ] remember you only need deposit formulation. Once pre filled apply target shade over the top apply liberally leave to process.

Alison waited a week to get back into see Paul. This is not acceptable it should have been corrected on the day. In some cases this may not be possible in this instance it would have been. As mentioned with the issues created a pre-fill to replace the pigment removed would give the hair depth of tone and solves any issues of fading.

Alison asked if it might be a good idea to put some pigment back in the overly blonde roots. { How did she know to ask for this? yes i advised her.} Sadly Paul still in a hurry still taking short cuts indicated this would not be required one application would be enough. Well one would be enough and look fine as she left but long term in the days and weeks ahead? It will fade.Paul applied the 4N Demi formulation directly over the top and the colour was restored to a rich solid all over Chocolate Brown.

However Paul has taken short cuts. This colour will fade he may well lose a client through what lack of service! The colour did start to fade within a week. Sheila went to a different salon Carl lost a good client.

Here is my thinking on the Fix:

In this instance if our goal is  to achieve a rich chocolate Brown. I have re introduced the missing pigment to the root area, to prevent fading and give depth of tone. However i will also need to control that warmth to get the correct depth of colour.

              look for location of orange section blue green section.

Lets look at the chemistry of a formulation.

4N has a Blue green base.

Check your colour wheel on your product ! green is made up of Blue+Yellow.

So given that we put on 7G the gold + Yellow + Red+yellow= orange

The 4N Blue + yellow +Blue= green

The out come of this formulation is the Base of the 4N will control or neutralise the warmth creating a wonderful rich chocolate brown.

As you can see from the colour wheel Orange sits across from Blue Green of the colour wheel so a perfect rich shade is possible.

Finally the after shot again provided by Alison I did not carry out this colour fix but did advise her at various stages throughout the process in return she allowed me to share the experience.

Out come

The chosen formulation controlled all warmth and left her with a rich dark brown filling in all those unwanted shades and the nasty root lift. Again this was all done with a Demi formulation for all those interested the process time is only 20 minutes so once applied  it’s a very easy way to repair poor colour issues. As a formulation it is none progressive so will not over deposit. it will last and stay rich and deep and healthy looking. Alison now has a new Stylist and is happy to be a rich dark brunette shade again. Sadly the experience has put her off trying again for a new multi tonal look.lets hope over time her new stylist gains her trust.

Pre lighteners Blonde hair toning


Welcome to BACK2MYROOTS B2MR.  Regular postings of fresh new topic’s

Bleaching Lifting and Toning:

My goal is to post topic’s on various aspects of our industry. Hair colouring. The process. The techniques.The skill.The knowledge.

All of these skills come together to enable us to carry out many different processes and applications on our clients who trust us to be both skilled and professional.

Bleaching and toning hair is a subject I have covered in the past but it seem’s to get researched for information constantly as stylist’s and client’s look for information on the subject

Full head bleaching or High lighting are a process that requires lifting or lightening the hair to a point of removing enough of the hair’s natural pigment. To then create a natural looking shade from light brown or copper to blonde depending on the natural level or colour of the hair . How do we achieve this?

As always it starts with a consultation with you client or as a client with your stylist. This is key especially with bleaching. Past history. Condition. Goal. Expectation.

At this time it should be decided if the hair is in a condition that is ok for this process. Be it just a root application or new look. If a root application then the key is not to over lap the product onto hair that has already been processed. If in any doubt do a strand test.

Other tests you can do to see if the hair can withstand bleaching.

1/ When wet does it stretch eventually breaking?

2/ Drop a strand test into a glass of water Healthy hair will float. over processed will sink. If this is the case. chances are it over processed and damaged. It will not hold colour much less toner.

Before proceeding a regime of conditioning will be required.Try to get the hair to float in that glass.

Hair Lighteners.  Decolouriser’s Bleach, High lift Blonde Tint.

My reason for putting these thoughts in is because of the amount of very poorly done over processed bleached hair i noticed. Breakage on the crown. Poor and patchy lift. Lack of tone why is this?

Bleach and pre lightening. 

Powder Bleach, Oil or Gel.

Before Embarking on lightening hair. We have to understand the chemistry of the product and how the process works, sounds easy and yet it’s so easy to get it wrong.

Hair Lighteners come in many forms. They are designed to lighten the natural pigment in the hair they are known as an Alkaliser. During this lifting process warmth from the hair’s pigmentation is exposed as it lightens. This warmth has to be controlled,the amount exposed is dependant on the Natural level of the hair and the desired amount of lift. so choice of strength of developer plays a key role.

How do these products work.

These are products that supply Sufficient Alkali to destabilise hydrogen peroxide. When these two elements are mixed together the Hydrogen attacks the pigment in the hair, the lightening process begins. Depending on the strength of peroxide plus timing will dictate the amount of lift we can achieve,we must also consider the natural hair level as a starting point. Hydrogen Peroxide is Stabilised in a bottle with a low Ph around {3.00-3.5} adding the lightener be it {powder or liquid-gel} brings the mixture up to a Ph of around 9.0 triggering oxygen release. This will be noticed by expansion of your formulation or change in consistency whilst mixing.

Types of Lighteners:

Bleach powder Lighteners. These are for the most part Stronger and faster acting than oil and boosters. Generally used for off scalp Lightening application. { always do skin and stand test} 

Lifting ability depends on. The strength of hydrogen peroxide and will also be dictated to by timing and the natural starting level. Having a clear goal of whats expected, or you are trying to achieve is also very important.

Hydrogen Peroxide comes in different strength’s or Volume 10. 20. 30. 40 are standard in the hair industry, 20 volume is advised for all scalp applications. No higher, always consider the use of heat it’s not always required or advised.

Lotions Oil -Gel:

These have a smoother consistency. They are formulated to protect the skin/ scalp from the lightening process, again for scalp application 20 volume is the max recommended for safe application.

{Be advised that adding heat/ dry or steam will change the way these products react: powder bleach can dry out under heat!

Ingredients.

The chemical Structure of lighteners are Ammonia. Ammonia hydroxide. Magnesium silicate,and sodium, quite the mix all lighteners have to be mixed with hydrogen peroxide, of a desired strength or Volume to attain results.

Take note! If the hair has been coloured with, any kind of metallic rinse, colour or stain. It could create a heat reaction this can cause burning so do your home work! Ask the right questions in the consultation process, if in doubt do a strand test. see article on metallic salts in products. 
Stages of Lightening:

When lifting or lightening hair, it goes through what is known as the 7 stages of lift. It has no limits it can remove all pigment from the hair. If left on or the lifting action is kept going, this would be by re-applying fresh formula on top of any application to keep the  lifting  action going.

Remember the Colour wheel:  {you can see shades in the outer wheel }  

                                             

The stages are as follows

Red-Brown. Red. Red-orange. orange-yellow. yellow -orange.

yellow.pale yellow.

The first colour is always the stronger shade!

The deeper the base shade the more stages of lift required its a journey don’t rush it.

Advantages:

*lightens hair*Can be used for colour Correction.

*Adds Texture.

Disadvantages:

*re-growth needs to be maintained.

*Can damage hair.

*Can cause Skin irritation.

* Hair should be protected from Uv -sun light.

Summing Up:

A very useful Tool for us to have but should be respected and understood. I advocate the best path is the one with the least chemistry possible. Full consultation prior to any chemical service is essential. If in doubt do a strand test.

The main reason for this topic is to address toning.  Having lifted the roots to blend be it with previous coloured full head or addressing high lights that are growing out.

We now have to look at the degree of lift and the shade that needs to be toned. At this point understanding the colour wheel is key as is using the correct formulation.

In so many cases the things that can go wrong with toning are. Bad choice of toner. Bad formulation.

Bleached  /decolourised. Lifted hair is by nature very porous and will take any application of toner readily and quickly so once applied stay with it as it works it’s magic.

I class Toning as early stage colour correction it’s an art.

What we are talking about here is. Lift and deposit:

For example. Lets use a natural level 6 this is classed as Dark blonde/mouse. It is a perfect level to work from to introduce natural looking Blonde shade and tone.

There  are many different types of pigment  available to us. From pre mixed tubes of concentrated pigment these might be. Ash . Violet. Amethyst depending on the tone you require.

Normally they will have a shampoo like base and are worked into the hair after the bleach has been washed or rinsed out and prior to conditioning.

Another option. Professional colour pigment tubes some have the ability to allow us to change their chemistry. They deposit pigment with any lift.  Understand your product how they work as well as having a clear goal. Read all instructions carefully.

As you can see with the above chart level six sits within the middle section of the chart. To get to a level of lift to be able to tone. We have to lift four shades into the area of pigment exposed around level 9.

This can be reached with a bleach de-colouriser or it may be possible with a high lift tint using 40 vol developer.

For the sake of this topic we are looking at. We are using an example of bleach being used.

Some may say level 6 to 9 is only three levels but that is misdirection for we have to lift through level 6 to get to level 9! In real terms we are looking at 4 levels max depending on the pigment base you want to work with. ie How much yellow you want to work with to create your shade and tone.

For levels of lift the above chart will show levels and timing from said developers:

Once we have reached a target of lifted shade to a nice even base pale yellow would be desired for a nice blonde. Anything from a very light Orange hue to very pale yellow will give an acceptable level of lift and pigment for toning Blonde.

This chart above Shows.  Both undertone exposed through the lifting process and then the pigment required to tone to a natural shade at the level lifted to.

Note you will be working at levels 8 to 10 anything darker that this will be more like low lights caramel or burnt honey tones. Because you will still have an orange hue. Darker than level 8/7 and down. It should be noted that really shades darker than level 7 are not really classed as blonde.

This I think is where mistakes are made. Considering the level of lift choosing the desired pigment required to tone. To often Ash toner is reached for. When you can see from the chart Ash really will only work for pigments that are of an Orange hue. Ash pigment used as a toner on. Yellow will create a Green hue! Why? Well what does yellow and Blue make ! da Green

Think about our primary colours the secondary shades then think it’s all about balance adding back what we have removed,But at the level we have exposed or are working in.

Guess what it’s back to know understanding trusting the colour wheel and the law of colour.

A small very basic colour wheel but easy to understand Opposites neutralise so yellow requires Violet!

Nice healthy natural shades of blonde lifted and then tones for dimension.

Healthy good condition long blonde hair is possible. It takes time patients client and stylist working together.

Finally bleached and toned full head colour all is possible . Use the right products understand these products. choose the correct formulation and timing.Think the process through!

Thanks Mike B2MR

Pre lightening hair. Bleaching lift pigment tone.


Welcome to BACK2MYROOTS B2MR:

A place to share thoughts post comments and idea’s on matters relating to hair colouring skill and techniques and anything industry related.

                               how not to bleach!

How to Bleach your hair:

A huge topic with so many different answers options variables.

Above i found this information for bleaching a head maybe it was put up in jest if that was the case it’s in bad taste and dangerous in content or lack there of. If not in jest then very dangerous if taken seriously by some one. We should always consider the content of what we post and the damage bad information can do !

Lets look at it in a little depth:

Step one suggested supplies.

I would suggest for an on scalp bleach an oil bleach rather than a powder. {why} powder bleach is harsh on the scalp, has a tendency to dry out creating patchy lift.

Oil bleach mixed with booster will give even lift and will not dry out. { Do not mix with any higher volume of peroxide than 20vol} Skin test and possible stand test is advisable.

*If a virgin application start at the ends  work up to roots, the roots will always lift the fastest.

*If a re-application try not to over lap re-growth application over hair already bleached.

*If trying to lift out one fashion shade to apply another go carefully don’t just slap bleach all over remember this hair has already been lifted so is fragile. You may well encounter  build up of colour the ends may well be harder to lift.Compromise and toning may be required .Do not just keep bleaching!! hair can only take so much abuse!

As i said many variables to lift out residue of old fashion shade try Clarifying shampoo or a bleach bath Shampoo bleach washed through and worked into hair. {if doing this stay with it constantly watching} as pigment and or toner is removed

                          If making up a cocktail to lift old shades out try.

*1/2 oz Clarifying shampoo.

*1oz      Water.

*1oz       20 vol peroxide {or cream developer}

*1 oz      powder bleach.

Apply to clean towel dried hair, work through on area needing lift for 5 to 10 mins. watching all the time wash out rinse thoroughly.

Got side tracked as is aid huge topic, foil is not advisable for an all over application some schools of thought advocate heat, i do not!

The biggest heat loss in the body is through the head so why not use this if heat is required a plastic bag over the application with suffice. { heat only seems to speed up the process but given that the formulation for lift is dependent on the volume of peroxide chosen why rush it’s a process} 

Lets Touch on second stage mix powder bleach until creamy!

How informative is that!  normally direction and mixing instruction come with products they need to be followed, the goal is to get the correct mix of lifting agent to peroxide.

With powder bleach normally 1-part Bleach decolourizer powder to 2-parts peroxide but follow each products instructions:

No Mention of Gloves!!

                                                       [as stated on scalp no more than 20 vol}

example of colour home kit  contents on right oil base with boosters:

below on left natural level  on right lift attained

I recommended oil bleach this comes with a bottle of liquid+sachets of powder you can mix one or two sachets or boosters with the correct amount of liquid. mix together until a gel then add the recommended    amount of peroxide mix thoroughly.

Another option for removing  some of the fashion shades is Colour remover it works very well but i must state that some of the fashion shades really stain  heavy build up of staining can cause problems.

                          lifting agent bleach powder:

Hair Lighteners:  Powder Bleach, Oil or Gel.

Before Embarking On lightening hair one has to understand the chemistry of the product and how the process works.

Hair Lighteners come in many forms and are designed to remove Colour from the hair.Basically they are Alkalisers.

How do these work:

They are products that supply Sufficient Alkali to destabilise hydrogen peroxide, when the two products are mixed together the Hydrogen attacks the pigment in the hair and Lightens it.

Hydrogen Peroxide is Stabilised in a bottle with a low Ph around {3.00-3.5} adding the lightener be it {powder or liquid-gel} brings the mixture up to a Ph of around 9.0 triggering oxygen release.

Types of Lighteners:

Bleach powder Lighteners are for the most part Stronger and faster acting, Generally used for off scalp Lightening application. { always do skin and stand test} Lifting Ability depends on the strength of hydrogen peroxide.

Lotions Oil -Gel:             

These have a smoother consistency and are formulated to protect the skin/ scalp from the lightening process.

 {Be advised that adding heat/ dry or steam will change the way these products react: powder bleach can dry out under heat!

Ingredients:

The chemical Structure of lighteners are Ammonia.Ammonia hydroxide,Magnesium silicate,and sodium. quite the mix all lighteners have to be mixed with hydrogen peroxide.

{ Be advised hair that has been coloured with any kind of metallic rinse, colour or stain, will create a heat reaction that can cause burning so do your home work!}

When to use:

A key tool for colour correction, but generally they are used when other products available cannot give the desired degree of Lightening.{ Remember High lift Tint will only give max 4levels of lift when mixed with 40vol Peroxide} 

Uses: High-lights, pastel blonde look when hair is strongly or pigmented darker shades.

Mixing:  Always follow Instructions on each given product! for lotions/gel /oil double amount of Hydrogen peroxide is often called for. lotions and lighteners/Booster powders must always be mixed in Sequence,{note: mixed out of sequence can result in uneven lift!}

Stages of Lightening:

When lifting /lightening hair it goes through what is known as the 7 stages of lift. it has no limits it can remove all pigment form the hair.

Remember the Colour wheel: {you can see shades in the outer} wheel      

The stages are as follows.

Red-Brown. Red. Red-orange. orange-yellow. yellow -orange.

yellow.pale yellow.

The first colour is always the stronger shade!

The deeper the base shade the more stages of lift required its a journey don’t rush it.

Advantages:

*lightens hair.

*Can be used for colour Correction.

*Adds Texture.

Disadvantages:

*re-growth needs to be maintained.

*Can damage hair.

*Can cause Skin irritation.

* Hair should be protected form Uv -sun light.

Summing Up:

A very useful Tool for us to have but should be respected and understood, I advocate the best path is the one with the least chemistry possible.

Lets re touch on bleach bath/ Cocktail:

What is a bleach bath used for? It is a tool that we have at our disposal to gently lift unwanted pigment from the hair. It is classed as the first line of attack when doing Colour correction:

One would use this formula to lift pigment {note it does not remove pigment} prior to toning or adding your fun colour.

As i have stated before if you are going bright red you don”t need to remove all pigment yellow or orange is fine! if you want true blue you have to get rid of the yellow toning would do this!

Formula for Cocktail. 1/2 OZ Clarifying shampoo 1oz water. 1oz 20 vol peroxide or developer. 1oz/or scoop of bleach.

Wet hair wear Gloves apply and work into your hair for 10 to 15 mins. wash out really well if you don’t get enough lift don’t give up mix up second batch re apply. don’t rinse out re-apply the water stops the action. Remember lift is all about timing;and observation.

It is a miss conception in thinking that 40vol is stronger than 20 vol not true its just long lasting in how long it lifts for {How long the hydrogen gas re acts the oxygen}.

What is toner

                              High lift Blonde series:

Toner is basically a tube or bottle of pigment no peroxide designed to neutralize the unwanted pigment you have exposed or created.  deposit only no lift when using toner you need to watch what you are doing it keeps on working so you decide on the tone you want!


All these shades are toners:

B/green/orange base beige neut pale yellow.

G/ yellow/orange base gold

V/ red/ blue Violet neut yellow

A/blue /yellow Green Ash neut orange   


To the right a classic case for toning in my view way to yellow gold?

What would you do here?


To Beige this out lose the warm root hue Violet Toner is required

worked into the hair for a few minutes it will neutralize the warmth

their is no exact time for toning it’s a visual hands on exercise.

do not apply and walk away thinking 20 minutes should be fine!

you may well get over deposit and sludge!

A really well done look both bleaching and tone look good and very natural. How things should be done.

                                            http://www.trichocare.co.uk/

I found the above sight they have a product for doing skin allergy testing worth a look!

Here is some information on the above product with so many chemicals and trace elements in colours a topic to be covered very soon  one cannot be to careful.

Quote from sight:

Colourstart is a unique patch test used by hairdressers as a skin allergy test. These tests help the hairdresser to check if clients are likely to have a problem with hair dye. The alternative is often unpopular and impractical for clients. Colourstart is used on clients who do not have time to visit the salon 48 hours before every application. It is used on clients who do not want hair dye left open on their skin.

Colourstart is one of the most important advancements in professional hairdressing. It helps to improve client satisfaction and safety in the salon

Due to its benefits and ease of use, Colourstart is rapidly becoming an industry standard.

Hair colour correction challenges


Welcome to BACK2MYROOTS B2MR : Regular postings of fresh new topic’s

                                   Hair Colour Correction:

I have decide this week to post topic’s on. Bleaching. Toning. and of course colour correction. Colour correction that journey into the unknown. That adventure that we have to be fully prepared for. the one that can and will at some point challenge us all.

To succeed we need. Knowledge.Skill. Technical ability. Good products and what? Communication and consultation skills. Colour correction starts with consultation!

Elasticity.Porosity.Moisture level. Overall condition key to successful out come and application.

An honest consultation who wants to end up with! An over processed shapeless mess!hardly an endorsement of ones skill or ability.

After a few days of postings hopefully providing information on many aspects of hair colouring.From the colour wheel to Ph Chart . reviews of Pigment. Lift. Deposit. Tone developers timing.With all the information provided one should have more knowledge to embark on corrective hair colour issues.

A huge topic how do you define or categorise it? What is classed as corrective colour? cause concerns Options:

Causes.

Client has Indulged in a cocktail hair colour party trying to get that salon look at home on the cheap! Or Sadly a poorly done colour service done by an unskilled hairdresser.

A mixture of both of the above some salon visits some home colour therapy! Can and will result in need of expert help and advise.

What must we consider when Taking on a Corrective colour  challenge?

Do some salon over charge for this service? sadly yes in many cases!

Are all stylists qualified to do this service? certainly not many just don’t have the knowledge and experience!

Are clients punished because they need this service? Yes, quite often they can feel like they are being punished.

The key to successful colour correction are as follows:  

Firstly as a client consumer. If you find your self in this dire situation. I really think it’s time to take stock seek out professional advise from someone who knows what they are doing. A professional that you as a client can trust.A person that has your best interest at heart!

Please don’t just buy another box of instant over the counter wonderful fix!

If it’s a poorly done Job by a hairdresser. I would suggest refund go else where. I would not trust them to put right a wrong!

As a Stylist:

If you as a stylist don’t feel comfortable. Don’t feel you have the skills to do corrective work, be big enough to admit it! Drop the ego get the skill.

The Key to successful Correction. Is communication and honesty by all concerned. History, concerns,  reservations, Expectations, should all be discussed.

The Consultation

This must be an honest conversation. Both parties must decide on a goal and what can realistically be achieved! {it is worth noting that correction can take more than one visit}

A Commitment to work together for how ever long this journey might take.

During the consultation, a stylist must use all tools available to them. Ask as many questions as possible thus getting a full history of events running up to this point!

Touch and feel,visual study of the hair.{ look for banding. fading. build up. breakage.porosity.} 

Do a strand test. Healthy hair floats, over processed hair sinks. Hair that sinks will not hold colour! Step one is to re build that moisture level 

How ever challenging the correction is. How ever good you are. We all like a challenge and to show off!   { oh yes it’s correction so big earner!}  But make sure you know what you doing. Are your up to the task.

What is classed as corrective hair work? Badly done Colour, Wrong Colour or shade. Poor coverage issues. Over Deposit. Damage by over process long term abuse.                                                                                         

Picture to the above is corrective from the first shot:

Colour added but existing Blonde utilised. Colours added all Demi formulation for deposit no lift

Stylist consider this 

If at the end of the day you don’t get a good feeling about. The client commitment or if it’s not going to be a good advert for your skill. Why take it on? EGO!

Think about this. Really damaged over processed hair, that is fading, falling apart a lot to take on. As soon as you agree to attempt to correct this you are saying. I take on full responsibility for this and all that has been done in the past!

A huge risk. Remember if it’s not going to be a good advert for you, that it can cause damage to your reputation. Hard as it is their is nothing wrong with saying. I’m sorry this is just to damaged to work with at this time. Recommend products see if there is commitment to work with you!

If the motivator is driven by your fee you should not be doing it!  

You should be thinking long term. This could be a long term relationship with a client. One who will trust you for ever, so be honest look at it as an investment! educate them.

The Next Step: 

So we have decided that we can and want to proceed:

Corrective Colour will usually be one or a combination of the following:

*Wrong level: the hair is to dark or too light.

*Wrong Tone: the hair is to warm {Orange} to cool {ash}

*Uneven colour: Dark ends. Lines of demarcation. light { hot} regrowth.

* Insufficient or poor Grey coverage.

* Colour that won’t holds on ends and or fade very quickly.

The key to understanding corrective colour is. The understanding of what pigment is missing from the hair. What needs to be replaced or removed?

Hair colour is about balance and harmony. Ask your self do i want utilize or neutralize the shade exposed? The chart below shows the relationship of tone and corrective tone. Remember that perfect balance of our primary colours Red, yellow, blue.

So as an example lets look on the chart at undertone orange {orange as we know is made up of red and yellow}So to bring balance to a natural level 7 we would add a corrective Blue Tone! cool ha.

You must learn to trust these charts to get the correct results:

It would not be possible to give an example of a corrective case, They are all different just way to many possibilities and things to watch out for.

Problems:

Colour may not be removed evenly over the entire head. Due mainly to varying porosity and build up. Always work from dark to light! Repeat on dark areas before moving on to lighter area. Be patient always protect virgin hair – regrowth.

Lifting the cuticle causes damage to the hair shaft. Rule use as little chemistry as possible, protect that condition get that hair Ph back to 5.5!

Test the hair: 

Do not remove colour if:

* Hair is extremely porous or slimy, does it stretch when wet? sort of cotton wool Like!

*Skin is broken and or sensitive.

*Do a stand test, do a skin test be safe.

Repeat performance:

In a perfect world we could say this is a one off service! But be prepared for follow up fine tuning to get the perfect results.

Decolourizer or Bleach  one of the key tools needed for corrective service when mixed with the correct volume of Hydrogen peroxide on the market now many really good colour removers. 

Finally:

Follow-up this involves. Recommending the correct products, to maintain the colour and hair condition it’s your prescription for success!

Book a follow up appointment. Within two weeks is ideal, so colour retention can be checked and adjusted if necessary!

Remember it’s a journey an adventure with the right tools knowledge and education correction can be fun!    { if you don’t have the skills and confidence seek help get the knowledge}

Bleaching lift,tone Condition


Welcome to BACK2MYROOTS B2MR regular postings of fresh new topic’s http://www.back2myroots.co.uk/

An up dated review on bleaching lifting and tone always worth re visiting and promoting.
