Hair Colour: Brief history and facts

12 Apr

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.

 

Brief history and some sound information on the chemistry and development of all hair be it professional or home.

Ammonia  PPD Free Hair Colour Ingredients:

 

PPD Free Hair Colour ingredients-

Until the early 1900s, hair coloring was made from a wide range of herbal and natural dyes. Flying in the face of other chemists who found the development of hair coloring trivial and unworthy of their time, French chemist Eugene Schuller created the first safe commercial hair coloring in 1909. His invention was based on a new chemical paraphenylenediamine.{ has a petroleum ring to it does it not?} As does the newest colour  delivery system  MEA based from ethanol-Ammonia see a pattern.

 

 

Ammonia Friend or foe!

 

The two main chemical ingredients involved in any coloring process that lasts longer than 12 shampoos are:

Ammonia – This alkaline allows for lightening by acting as a catalyst when the permanent hair color comes together with the peroxide.

Like all alkaline products ammonia tends to separate or open the cuticle and allow the hair color to penetrate the cortex of the hair changes the Ph from our desired 5 to 5.5 to 7 and beyond.

Detergent are also an Alkaline when we mix detergent and small amount ammonia we can create a very basic foaming semi permanent or a shampoo rinse!

 

Hydrogen Peroxide (also known as the developer or oxidizing agent) This ingredient in varying forms and strengths, helps initiate the color-forming process and creates longer-lasting color.

Hydrogen peroxide is made up of two atoms of oxygen and two of hydrogen H/2O/2 available in both cream and liquid form, In most professional salon found as a cream. Hydrogen peroxide is measured by % hairdressing professional refer to it as being measured in volume.[this relates to the volume of gas being released in the chemical reaction] for the majority of hair coloring the developer is maintained at 30% volume or less.

 

 

Alternatives to industrial  professional tints:

These would be known as natural hair colour derived from plants and root extract, not to be confused with some of the herbal ammonia free hair colour marketed today. 

It has been recorded historically that ancient civilizations dyed their hair using plants. Some of the most well known are henna, indigo, Cassia obovata, senna, turmeric and amla. Others include katam, black walnut hulls, and leeks.

Presently, there are some companies that do sell alternate-based dyes for people that are sensitive to PPD, a chemical found in most hair colors.

 

These PPD.free products are said to be safer products that avoid the side-effects of most industrial tints. The safer alternatives generally contain fewer potentially toxic compounds or are plant based .These products are available in a variety of different formats those being. Temporary, semi-permanent and permanent options.

However, these products typically do not last as long as industrial tints once again the engine driving the colour can be classed as herbal but it may be just as toxic as Ammonia! grain alcohol known as Denatured alcohol for example Silicone and oils.

 

So it makes sense to use a reputable, ethical, safe hair colour!

Good luck with this still not convinced these companies are totally honest in the way they represent the product or the chemistry of the formulation.

 

Types Of Products:
Hair colourDyes are available today in all forms. Liquid, powder, oil, cream and gel, etc. Mascaras, crayons and sprays are used as temporary and semi-permanent dying, whereas gel and other forms are used for permanent styling.

Once again the products all have a different edge hook oil, silicone, metallic salt. wax. the list goes on!

We are  all unique! and no one else has exactly the same hue as you!

You might look black, brown, red or blonde, but there are subtle differences.Amazingly nature creates a different dye for everyone using only two types of the natural pigments “melanin”: umelanin (black pigment) and pheomelanin (red/yellow pigment).

In most case the skin colour and tone our eye colour all those different flecks and indeed our hair colour a multitude of shades tones all make us unique and normally compliment each other.

It is all of these pigments that we encounter when deciding to embark on hair colouring. It is this pigment and levels natural shade that we consider when making decisions on a new colour formulations. Knowing what products are how they work the chemistry of any given products is key to being successful and making the correct colour choice and formulation decision.

 

I hope this has helped you a little please leave comments views and thoughts Mike B2MR
