Misinformation Hair colour product knowledge


Welcome to BACK2MYROOTS B2MR regular postings of fresh new topic’s

It is my goal to create a platform that over time will become a place to share thoughts review hair colour and products.

How confusing is it for both stylist and the consumer when you can go on line for advise and sound information and you get material such as below. quite shocking!

What is written in the heavy print is my view of course only my view!! However I found this information in this article miss leading and quite scary to think it’s posted as informative educational material in the public domaine.

Always research don’t trust all that you read as being correct knowledge is power  a little knowledge is dangerous! Stay informed current up to date have high standards and expect nothing less from those around you!

Lets take a look:

I have written my response in heavy print:

TYPES OF HAIR COLOUR

Permanent Colour:

Permanent colour gives you 100% complete coverage. Most permanent color uses peroxide (10 to 40 vol.) and ammonia. The downside is regrowth of new hair – it is a different shade and will leave a line of “demarcation”, or regrowth.

Most permanent hair colour uses 10 to 20 volume peroxide 40 vol would only be used for high lift blonde formulations and in maybe an extreme case! In most cases 40 vol is not recommended for scalp application. this type of application requires colour balancing unless first application. Issues with excess warmth will occur using 40 vol developer! 

Not all colour is driven by Ammonia many options available always find out what the alkaline is in your colour!

Semi-Permanent Colour:

Colour usually contains some ammonia and uses a developer of 10 to 20 vol.

Although it normally contains something to slightly open the Cuticle it does not have Ammonia nor does it have Peroxide much less 10 to 20 vol.

Demi-Permanent Colour:

Uses peroxide in low vols. (under 10 vol.). Many have no ammonia and leave little damage. When the color fades, it does gradually so it leaves no line of demarcation.

Normally uses around 5vol for the oxidation of the colour molecule may have low amount of ammonia or some other substance to open the cuticle for slightly deeper deposit. long term use of this formulation will result in build up and possible re growth line slow fading, ideal for Grey coverage with out going permanent

Semi-Temporary Colour:

These will last a short time (1-4 weeks). The usually incur no damage to the hair. You can expect about 40-60% gray coverage.

A direct dye/stain lies on the surface of the hair very little deposit so fades as washed whilst will blend Grey hair  some types more than others will not give full deposit will build up over time, they s sometimes have an alkaline in them to enable a little deposit.

Temporary/ Colour Rinse:

Colour lasts from one shampoo to the next and is deposited on the outside of the hair shaft.

As with a Semi permanent these can and do vary in their chemistry and how long they last depend on amount of washing and porosity of the hairthey can cause staining issues

Levels of Hair Color:

1=Black 2= Dark Brown 
3=Dark Brown
 4=Brown
 5=Medium Brown
 6=Light Brown
7=Dark Blonde
8=Light Blonde
9=Very Light Blonde
10=Light Platium Blond:

A standard International colour shade chart:

1black                      1/0

3Dark Brown             3/0

4 Medium Brown       4/0

5 light Brown             5/0

6 Dark Blonde            6/0

7 Medium Blonde       7/0

8 Light Blonde            8/0

9 Clear Blonde            9/0

10Extra light Blonde   10/0

COLOURED HAIR CARE TIPS

Coloured and treated hair needs extra special care to keep it in good condition.

Wear hats, scarves or products with sunscreens when in the sun, to help protect against color fade and the drying effects of the sun. Leave in conditioners generally contain sunscreens to protect against color fade. Rough shampooing can strip color or dry out hair, so shampoo gently with a shampoo specially created for colored/treated hair. Condition regularly with an intensive conditioner to restore vital moisture and luster to colored/treated hair.

SHAMPOO COLOUR ENHANCERS:

Use colour enhancing conditioners as color grows out to help blend root areas.

Be wary of these colour enhancing products they stain and can effect the hair for future colouring processes :

Do not wrap your wet hair in a towel turban after a shower. The added friction can knot and damage vulnerable wet hair. Instead, carefully blot hair dry.

Don’t brush hair when wet. Comb with a wide-tooth comb, working tangles out as you move from the end towards the scalp.

Don’t overdry. When you blow dry, dry the hair until it is almost but not completely, dry. Leave some moisture in to prevent static.

Well what is over dry? leaving hair damp will make it loose style shape  Hot ceramic irons take care of all moisture just use a blow dry heat protector don’t leave it damp!

Use care when styling. When using styling appliances, use thermal protector for maximum protection. Avoid aggressive manipulation of the hair.

Well this contradicts the about don’t over dry

Use hairspray or spritz with moisturizers and sunscreens to finish the hair. These products will provide continual protection throughout the day.

Personal choice some with silicone will tend to make hair limp

Don’t spray lightening agents or put lemon juice in your hair.

Yippee one to agree with

Support your style with a perm. Just because you have color treated hair doesn’t mean you can’t have a perm. In fact, a perm specially formulated for color treated hair can add wonderful body, fullness and texture to complement your color.

Well who has perms these days colouring and perming is double processing will damage dry out cause colour to fade:

What is written in the heavy print is my view i found this information in this article miss leading and quite scary to think it’s posted as informative educational material. Please please do lots of research when looking for information and advise keep looking until you find articles that are all giving the same advise and information.

Thanks MikeB2MR

semi permanent colour and other options


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

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

Semi Permanent Hair Colour:

Mousse, gels. Demi, permanent,

When we think about semi permanent colour we naturally assume slow wash out or fade maybe 6 to 8 washes up to 6 weeks. That’s what is says on the box or what we lead to believe not always the case!

In reality we have to consider so many things be it in the salon or at home? What we expect from this colour .What is my hair condition is it advisable?

Are we going tone on tone? Are we considering putting a darker shade than our natural level not a great deal is achieved putting lighter over darker!

If putting a cool Red {blue red} over say Blonde as it fades a pinkish, purple, hue could be left. bright true Red could fade leaving {red orange} hue.

The porosity of your own hair plays a part in how these colours may deposit. How long they last and how they fade, as well as the chemical make up of the product.

Buyer beware!

A product that is promoted as being semi permanent can still have ingredients in the formulation to open the cuticle and help with the deposit of the said colour.

This is not ammonia you can change the Ph thus opening the cuticle with money alkaline products shampoo can change the environment. Detergent/soaps, alcohol These will open the cuticle thus allowing stains to deposit slightly deeper into the hair.

It will over time create staining. It will slowly build up after prolonged use.

Hair in it’s normal state has a ph 0f 5.5 Anything raising or changing this level,this environment. Will open the cuticle to some degree. Some so called semi permanent might change the ph to as much as ph of 7!!!

In some cases they can leave behind trace chemical residue the same can be so of the mousse colour refreshing products Reds. Blondes.They can leave behind trace elements that build up and can effect professional colour applications.

In some cases they can effect the deposit of professional colour creating banding issues or poor deposit. see article on shampoo with colour pigments added.

 As a stylists always consultation it’s the key to a successful out come:

How many of you have cried their eyes out! after a colour has gone wrong? Been close to shaving your head after unfortunate choice of hair colour? Hands up! Yes ? With hair the colour of scrambled eggs…Dying your hair is not as easy as the adverts make it out to be.  I am not talking about the technique! Just the many things to take into account when considering hair colour both product and desired effect! 

It’s product choice.  It’s hair condition. It’s history of the hair previous colour. It’s application. It’s formulation. It’s timing. Oh did i mention skill and knowledge training?

The question arises:

I have coloured my hair it’s the wrong shade what can i do? Was it one tube or bottle or a mix pack?

When you applied the color did you mix 2 things together?  Was it a twist the top asking that you shake 2 suspended liquids together or were you able to apply it straight from the bottle with out mixing anything?

If you mixed 2 things you used a long lasting semi permanent, or what the pro’s call a Demi permanent. They usually contain a very low volume of peroxide and little or no ammonia, they use a different chemical to cause the oxidation instead of ammonia. such a detergent,  {in the form alkaline solution} some have a grain alcohol derivative in them maybe even metallic salts!

If it came straight from the bottle to your hair it was a direct dye or preformed dye molecule in an alkaline solution. The alkaline liquid causes the hair shaft to swell so that the large molecules of color will penetrate slightly into the cortex sticking to the cuticle. This is the principle that the washes out in 15 – 20 shampoos works, the cuticle can’t lie completely flat again because the colored molecules are in the way so each time we shampoo or wet our hair the cuticle raises or swells slightly and the rubbing action of our hands while we lather pulls a few of them off eventually we have none left and our hair is back to  nearly its original state.

Having said this continued use or applying to damaged hair you can and will get build up! porosity of hair it’s natural moisture level it’s Ph can be compromised.

DEMI PERMANENT COLOUR:

Two products mixed together much deeper deposit!

Demi  permanent colours use either low levels of ammonia or MEA {methylethylalamine}  in place of the ammonia, to oxidize  the colour molecule low level of  hydrogen peroxide less than 5vol this cause the indirect dye molecules to mature and develop into desired color. While this is considered Demi permanent because it does not lighten natural pigment with continued use it will slowly lighten the hairs natural level so could create regrowth issues and indeed over time fading issues!

The key here is not to over use and always assess the hair before any application:

                             Demi colour rich brown tone on tone deposit

The above model is a rich Brown tone on tone colour with a short textured razor cut.

Final option the one that covers fully but can create the most issues of effecting condition, deposit, banding, health and shine.

Permanent colour:

Normally mixing from a tube but in some form liquid or ge, mixing colour pigment with a peroxide mix  this is a process of lift and deposit. the colour may ammonia or be advertised as being ammonia free. MEA grain alcohol derivative in all cases the action is to change the ph of the hair open the cuticle, These products have hydrogen peroxide in them this serves to purposes it lifts your natural hair level , it also reacts with the colour molecule to help it mature or to develop it.

This is a process of lift and deposit and is permanent, many issues can arise in this choice of product from over processing to poor deposit to not attaining the correct or desired colour.

It is my personal opinion that any one want permanent colour should at least seek professional advise before embarking on this journey!

Finally a home colour correction tool:

Whilst doing research On line I came across a colour remover Product for home use not a thing I would normally promote. sold in most branches of Boot’s chemist B4 Colour remover.

The key to using any product is to follow the instruction to the latter.  Don’t take short cuts make sure you allow enough time to do this process correctly. This colour remving product is everything it claims to be I was very impressed. But remember it only removes artificial pigment if you have coloured your hair a number of times do not expect your natural colour to appear. If you have over time lifted your natural level with each colour application using permanent colour.you may be able to remove the unwanted pigment but your hair’s natural level will be lighter and in some cases very light if hair has been coloured over a long period. Remember none of these products  are a miracle quick fix. So do your re search become informed if in doubt have a professional consultation.

Before using or applying think about your choices and options: Then make a decision and live with the consequences. good luck hope this has been helpful.

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!
