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.

Alkalinity and Ph. The process of hair colouring.


Back2myroots :

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

When it comes to understanding the chemistry of hair colouring. Get educated not mislead!                         

As Hairdressers when considering doing  hair colour . We owe it to our selves and indeed the client to do the best job possible, more than that give the best service and advise possible, suggesting colour that works with skin tone and eye colour. Work with the best products available, understand the chemistry of the product how it works reacts with hair, what condition with it leave the hair in. Spend some time reading the technical manual in the colour chart know and trust your product.

Many hair colours today claim great condition no Ammonia. However claims of no ammonia does not always mean great condition, some times we sacrifice one evil for another. When no ammonia is present in permanent colour another alkaline is introduced as a replacement or substitute.There has to be a presence of an alkaline for the colouring process to work

We are talking permanent colour.  The process is not the same in Semi or Demi colour but they to can be misleading in their chemical makeup! So always get informed read the black stuff ask questions.

It’s all so complicated. Education, technical knowledge, a greater understanding of the products that you are using is essential. Understand what MEA is another favorite derived from Ethanolamine. Alcohol Denatured. Do you know what this is? It’s alcohol derived from fermented grain used as an alkaline it can be very drying but because a grain by product marketed as being natural! Very misleading

Why does Ammonia get such a bad wrap just because it smells ? The damage it can cause depends on the strength being used and the way applied timing, heat, temperature,

Ammonia! GET’S A BAD WRAP SO THEY CAN RELAUNCH OR SELL A NEW CONCEPT

High lift Blondes have an extra kick! Most hair colour lines have high lift blonde range, these again have an alkaline from some source however it may be that extra lift is promoted. In many cases companies also add  Ethanolamine to their high lift colour to open the cuticle more! They don’t normally advertise or disclose this fact it’s disclosed in the small print on the instructions on the paper work inside the box .

So why is MEA  such an  innovation? MEA now promoted to replace Ammonia can any one enlighten me?

Definition: 

MEA Monoethanolamine:

Can be used as a selective absorber and plays an important role in the production of Ammonia! MEA Monoethanolamine obtained from the reaction of ammonia and Ethylene. Ethlene a bio fuel so we are back to grain Alcohol! but derived from grain so natural! does this make it ok ? Would you think that good for hair?

Definition:

Alcohol denatured:

A general term for organic ingredients that contain the OH (hydroxyl) group. Alcohols differ substantially in their properties ranging from water soluble solvents like isopropyl (rubbing) alcohol.
Sounds good too!

Definition:

Ammonia:

An alkaline ingredient used in some permanent hair color. Ammonia is an ingredient that results in a chemical action that decolorizes the hair. A colorless, pungent gas, NH3,  first step in the nitrogen cycle. 

Ammonia is generated by fish urine and by the decay of dead fish and plant material. Many professional hair colours have 0.4 to 1.2% Ammonia be aware some companies have levels way above this quite low level of working alkalinity.

The choice dead decaying fish or fermenting Grain both really a natural source.
As we can see although some companies portray natural less harmful chemistry it is not always the case. adding natural oils or waxes to protect scalp to make application easier are all part of this process.

This is why knowledge research are key and empowering when it comes to colouring hair and the choices we make on products must go beyond what the sales rep or promotion material say.

I am not trying to scare just inform encourage thinking research! I think that we also need to cover the important role that understanding Ph chart and the role that it plays in the hair colouring process and indeed the chemistry of all chemical services performed on the hair.

                                       review of  aPh balance chart.

A little help with Ph balance chart: When we do any chemical service on the hair be it. Colour. Perming. Relaxing. We have to create an environment that enables us to get below the surface layer the cuticle layer of the hair ,

This is the outer layer that serves to protect the inner structure from both damage and moisture loss, the inner layer being the cortex and Medulla.

Once we have decide on the service we are going to perform in this case colour. The formulation we choose will dictate the amount of deposit the more we open the cuticle the deeper the deposit.

So understanding Ph, lift, deposit, are key to being able to perform outstanding colour services.

                               Three layers of the hair structure.

Healthy hair should have a Ph of 5 to 5.5  when we introduce an alkaline be it Ammonia which comes in many different strengths the stronger the more it will open the cuticle. The same can be said for other colour drivers MEA, Dealcoholised grain products. All serve the same purpose to manipulate the Ph of the hair to create an environment for performing any chemical service. The stronger the product the more the cuticle will be opened and the more damage can be done.It is essential after a process to re balance the hair and close the cuticle and restore that natural balance of 5.5.

This can be done with a chemical balancing product these normally have a Ph of 2.5 when introduced to the hair it will close the cuticle and restore the ph balance of the hair to 5.5.

Always be aware to consider the hair condition and assess during consultation before deciding on any chemical service knowing and understanding the Ph of hair is key to keeping it healthy and allowing colour retention or retaining moisture after the perming process.

Part of the consultation process should address the condition, porosity, moisture level. issues of fading. colour retention. These are all things effected by the hair’s Ph level being at a correct level.

It is also during this consultation process to not only assess the hair both by touch and visual inspection. but through communication getting a fully in depth history of past products used and indeed products being used at this time.

With so many products that manipulate our Ph mantle opening the cuticle to deposit anything from stains to silicone based products that over time will build up in the hair, note they can cause issues when trying to get even deposit in the colouring process.

This is why it is essential that as stylist’s we have a good all round knowledge of products and how they work on the hair during any chemical process.

Healthy hair should have a Ph of 5 to 5.5  when we introduce an alkaline be it Ammonia which comes in many different strengths the stronger the more it will open the cuticle. The same can be said for other colour drivers MEA, Dealcoholised grain products.

The stronger the product the more the cuticle will be opened and the more damage can be done.

Ok a brief stop to review Ph now we can move onto developers with so much more knowledge of the colouring process.

Developers:

This really is such a huge topic and so important choosing the correct strength is the key to success. Developers play such a huge role in the degree of lift and deposit we decide upon, allowing us to expose the pigments we utilise in the hair colour process. The formulation we chose to attain our target colour is a a blend of chosen colour level of developer timing. It’s just like baking the perfect cake! Mess with the recipe it will fail.

Lets work off an example of level 6. Dark Blonde. 6N on most  international colour charts

Depending on the level of peroxide we opt to use. We are going to introduce colour or add undertone from the hairs natural Pigment. {remember level 6 } This gets a little complicated, mainly because in some circles we are mislead as to lift we should expect, from any given strength or volume of  Hydrogen Peroxide. 10 volume or 3% Peroxide: In some circles it’s suggested that it does not lift. I would disagree with this thinking.

The lift you get, is enough to expose the pigment in the hair at that given level. So on our level 6 we would expose Red Orange, by Introducing this warmth into our equation. We have to decide on the role  it plays, how will it influence our colour.

Do we want to Utilize or neutralize the shade exposed? At this point we should consult our shade chart and yes the colour wheel, choose the shade to do the job not just the shade that you like in the swatch! The higher the volume of peroxide the more lift the more pigment to consider.

Note: 

Take a look at a colour wheel if 10 is the lightest then it sits in the yellow segment.

So working from our level 6 what shade would we expose trying to get to level 10? is it possible to get their? lets see.

* 10=  pale yellow off chart

* 9 =    yellow

*8  =     yellow orange

* 7 =    orange

* 6 =    red orange

And so on down the scale.

Level 6 + 10 vol 3% 1 level  still level 6 but with pigment exposed. red orange

Level 6 + 20 vol 3% 2 levels through level 6 up to level 7 orange pigment exposed.

Level 6 +  30 Vol 9% 3 levels through level 6 and 7 into level 8 Yellow Orange pigment exposed.

Level  6 + 40 vol 12% 4 levels through level 6, 7, 8. and into level 9 exposing yellow but still a warm yellow.

4 levels of tint lift. Will not give you lift from level 6 to level 10 you will always struggle with the issue of warmth. { even with a high lift Blonde using adjusted formula with a violet base to neutralize the pigment exposed}.

You should be able to see from this example, that as we lift hair from it’s natural level we expose pigment.This exposed pigment becomes part of our colour formulation,  seeing as we have introduced this pigment into the colour equation  we have to  decide do we want to utilise it or neutralise it. thus creating our target colour. Now we can take time to review and digest the very key points raised for creating perfect colour.

Fact:

Ask your self this question which is the stronger 10 volume hydrogen peroxide or 40 volume?

be honest. I would say that 75% would say 40 Volume!

The fact is they are both the same. the only difference is the 40 vol stays active for longer.[see timing chart]

Think of it like this you have a glass of water in each hand. One glass has 1 alkali dissolving tablet in it this represents 10 vol. The second glass has 4 alkali dissolving tablets in it. This represents 40 vol strength wise they are the same, the only difference is the 4 tablets will fizz for longer.

The difference is not the strength is the longevity of the action in this case lifting! so we are back to formulation and timing.

Having made it this far on our Colour bus journey.We can now appreciate the careful balance that is hair colouring. Having a fuller understanding of the hair’s structure, how we can manipulate it’s Ph, to facilitate the hair colour process. Have a better understanding of lift deposit and how to utilise and neutralise the pigments we expose and use towards out target colour.

You can see the hair colouring process is quite complex and does require thought and knowledge when trying to achieve the very best results.

In closing it was brought to my attention by someone who sent me a question via a hair site about Ph saying that they could not find any information on the subject, I thought this very odd but having looked through the NVQ the offcial guide [Hairdressing foundation] I have to say  i find it very odd that this topic is not covered in some depth.

If you want information on topic’s to ask question go ahead use the section on the Blog.

I hope this is found useful

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.

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 colouring the Chemistry. How it works.


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

Through out history man has coloured his or her hair from using tribal muds and stains to the days of fancy pre dyed and styled wigs. Discovering permanent ways to alter and colour our own hair. Having an understanding of how this process works is key to attaining good results without causing damage or having a hair disaster.
A French chemist Eugene Schuller. Discovered the first safe commercial hair colour around the early 1900’s. Using chemical paraphenylenediamine.
Today with over 75% of women coloring their hair to some degree or another. With either help form a professional hair colour technician or by applying store purchased home colour  It is also now more widely acceptable that a growing percentage of men now also colour their hair .
With society so acceptable of hair colour how does it work? What is the hair colour process.
It’s a finally balanced series of chemical reactions between the molecules in the hair structure, the natural pigments that make up the hair’s colour. Along with a formulation that may also contain. A peroxide and ammonia or some other form of alkaline to help make the process work.
What is Hair?

Hair is mainly keratin, the same protein found in skin and fingernails. When warm and wet it’s soft and pliable. When dry or heated it hardens and protects the hair’s inner structure.

The natural color of hair depends on the ratio and quantities of two other proteins, eumelanin and phaeomelanin. Eumelanin is responsible for brown to black hair shades while phaeomelanin is responsible for golden blond, ginger, and red colors. The absence of either type of melanin produces white or grey hair pigment deficient. It is having an understanding of these pigments that is key to successful hair colouring .Do we want to utilise or neutralise the pigment’s as we expose them in the lifting process.This in simple terms is do we want to sue the pigment to enrich the colour and shade or do we want to control or mask it!

Natural Colorants

As I stated at the start of this topic man and different cultures have been coloring their hair for thousands of years. Using plants extracts and minerals. It is these pigments found in such products as  (e.g., henna, black walnut shells beetroot juice.) others contain natural bleaching agents or cause reactions that change the color of hair (e.g., vinegar lemon juice). Natural pigments generally work by coating the hair shaft with colour  they coat the outer shaft some times lasting for several shampoos, however they aren’t necessarily safer or more gentle than modern formulations. So can have metallic salts in them. Some can and will build up on the hair.In some cases they cannot be removed.  It’s difficult to get consistent results using natural colorants, Skin test is alway recommended even with these so called natural products

Temporary Hair Color

Temporary or semi-permanent haircolors may deposit acidic dyes or direct dyes onto the outside of the hair shaft .Direct dyes are fully matured and so are to big to be readily absorbed into the inner hair structure.unless an amount of an alkaline is present to open the cuticle. In some cases smaller  pigment molecules are used they can more readerly slip inside the hair shaft  some using a small amount of peroxide.

If peroxide is used in  a product one should expect some lifting of the hair natural level and possible warmth from said lifting of the pigment. or none at all depending on formulation. In some cases, a collection of several colorant molecules enter the hair to form a larger complex inside the hair shaft. Shampooing will eventually dislodge temporary hair color. These products don’t contain ammonia,  but may have some other form of alkaline in them. If an alkaline is present the deposit will be more long lasting that normal temporary colour.

In normal temporary colour the hair shaft isn’t opened up during processing and the hair’s natural color is retained once the product washes out.

How Lightening Works

Bleach is used to lighten hair. The bleach reacts with the melanin in hair, removing the color in an irreversible chemical reaction. Normally after bleaching toning will be required to some degree to neutralise unwanted undertone exposed. The bleach oxidizes the natural melanin molecule. The melanin is still present, but the oxidized molecule is colourless.  Bleached hair that is fully lifted of pigment will retain a pale yellow hue. The yellow colour is the natural colour of keratin, the structural protein in hair.

Bear in mind bleach reacts more readily with the dark eumelanin pigment than with the phaeomelanin. Some gold or red residual colour may remain after lightening,again tis is when toning may be required to rebalance the pigment exposed.

Hydrogen peroxide is one of the most common lightening agents. The peroxide is used in an alkaline solution, which opens the hair shaft to allow the peroxide to react with the melanin lifting it in degree’s depending on the strength of peroxide timing and formulation.Of course it will also vary depending on the natural level of the hair .the darker the hair the more lift will be required and so the longer it will take to get a desired level of lift.The darker the shade the more red and orange you will have to contend with when trying to get to that pale yellow. required if you want a very blonde tone!

Permanent Hair Color

The outer layer of the hair shaft is the cuticle or order to permanently change the hair  colour and for new artificial colour to be deposited into the hair we have to open this cuticle.  We open the cuticle by using an alkaline and raising the hair’s natural Ph from around 5.5 up to around 7 in some cases higher levels are used this can and will damage the hair and lead to poor colour retention. The dye reacts with the inner portion of the hair, the cortex, to deposit or remove the color. Most permanent hair colours use a two-step process normally they work simultaneously. First removes the original colour of the hair at the same time depositing the new color. It’s essentially the same process as lightening, except a colorant is then bonded within the hair shaft.

Ammonia or another alkaline is the chemical that opens the cuticle and allows the hair color to penetrate the cortex of the hair. It also acts as a catalyst when the permanent hair color comes together with the peroxide. Peroxide is used as the developer or oxidizing agent it does this by aggravating the colour molecule and making it swell. The developer removes pre-existing color. Peroxide breaks chemical bonds in hair, releasing sulfur, which accounts for the characteristic odor of haircolor. As the melanin is decolorized, a new permanent color is bonded to the hair cortex. Various types of alcohols and conditioners may also be present in hair colour. The conditioners help  close the cuticle after colouring and re balance that Ph level to seal in and protect the new colour.Alcohol is quite drying on the hair and is also another ingredient used to open the cuticle in the colour process,It can be also found in semi and temporary colours again to help with deposit of the colour molecules.

In closing this rather long and  technical blog all is not what it always seems and appears to be. Understand that chemistry trust your knowledge and research stay informed question and think. As and raise question seek the answers you need. Remember This! The only stupid question is the one never asked!

The colour wheel lift deposit pigment tone,


Welcome to BACK2MYROOTS B2MR:

Regular postings of fresh new topic’s.

Having re posted a slightly changed version on bleach lift and tone yesterday I have decided to follow it with on eon the colour wheel lift and deposit for they all work together well. We all need reminder of the importance of understanding and trusting the laws of colour and the colour wheel. Be it for lift and deposit bleaching and or toning.

As a stylist do you  understand the ‘Law of Color’ ?  As they relate to hair colouring?Yes Laws? Oh your one of those! Hands on stylist who are fortunate enough to know everything. who don’t need to know or understand the law’s of colour. Your a free spirited artist!  Your just someone with a huge Ego who muddles along getting bye with hit and miss colouring mishaps! A stylist who when things go wrong blames the product! How and why understanding and indeed trusting the colour wheel is so important to succeed.

Hair color is an art.  it is also a chemistry it’s a process. The natural laws as they relate to hair colour  apply to everybody everywhere. They work off of a Natural scale of hair depth and tone one to ten. The  higher the number lighter the shade or level. Laws are simple they are  beyond one’s control they never require a second guess or questioning. Never the less we still insist on the odd experiment to verify them. When you come to accept the law of  colour cannot be broken then you learn to trust it, you always know the outcome. The laws of hair color  are important and often very neglected. It’s imperative that all professional hair stylists know why we do what we do. Why do you choose the color you do to use on your client?

When you as a stylist take the time to learn the universal laws of hair color. You will be better equipped to work with and advise your client on the best course of action and an ideal formulation for them.

What is colour?

Colour is light and pigment. When we color someone’s hair with the right choice of colour, we can emphasize their skin tone and eye color. When we understand these laws and trust them we can grow and improve. understanding is one thing trust is much more! We will never have to guess the outcome of our  results will always feel in control confident and professional.

Essentials of Color

There are three essential traits of color.  Working from a natural level. The any given natural level will always have a hue: a leaning towards one of the primary colours found in the hair example. red, yellow, blue. The percentage of the hue is called saturation. Gold or copper is a good example of a low percentage (saturation) of red. Tone is the lightness or darkness of a color. For example, Copper is a tone of Red with a percentage of Yellow and indeed in some case a tinge of Blue. Balance always

The Color Wheel

There are three primary colors: Blue, Red, Yellow.

They are called primary because all other colors are made from them. 

The secondary colors:

Blue + Red = Violet, Red + Yellow = Orange,  and Yellow + Blue = Green

Tertiary colors are made by mixing the primary and secondary colors together. There are six possible combination’s. They are yellow-orange, red-orange, red-violet, blue-violet, blue-green, and yellow-green.

Two colors are called complimentary colors if when mixed together they produce a neutral color.  They are located opposite from each other on the color wheel. When you mix any color with their complimentary color:

You will produce a neutral or browned-out color. sometimes Mud is created.

A colorist should not only always consult and understand the color wheel.

It is a tool that will be used almost every time you color a client’s hair. It will help you create colors with a better understanding of utilising and neutralising pigment and tone.  contrasting colors are placed directly across from their opposite.  This is very important since it is necessary to know which colors can be used to “neutralise” or “brown-out” undesired tones.

A good example of this and indeed a common issue for stylists is neutralising unwanted orange and yellow tones in the hair. When you know and understand the color wheel and can see that violet is the opposite of yellow on the color wheel, you can then choose a violet pigment in order to neutralize the yellow.  Violet being a even mix of red and blue. these will restore balance to unwanted yellow  creating a natural tone. If the unwanted color is orange, you can see that blue is the color to use to neutralize the unwanted tone. Orange being made up or Yellow and Red so blue is required to restore balance.See it;s easy common sense and understanding.

The color wheel is also separated into warm and cool colors. Blue (one of our three primary colors) is the coolest cool color and is also the darkest. It generally lives at a level three, masking out both gold and warm red tones or Hue!  The more blue that is added to your hair color the more it will produce a darker, cooler tone. Red or yellow (our other primary colours) are warm colors. Adding red to your hair color formula will create a warmer tone. Just as blue is the darkest cool toned color, yellow is the lightest warm toned color. Adding yellow to your color formula will always produce a lighter, brighter color. depending on the level you are working at Yellow normally comes out to play between the natural level 7 to 10 any level darker than this the yellow will be over powered by either the Red or Blue Pigment.

This is such a huge topic that one can expand on when introducing the effects of lift from chosen formulation and level strength of hydrogen peroxide or developer. These lifting agents will expose pigment as they lift the hair in the colour process adding warmth from the hair to your formulation.

So again understanding the colour wheel really is key.

Good luck Mike B2MR

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.

                        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 or lifts it.exposing the pigment left at any given level from degree for red shade through orange into yellow.

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 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.
