Human Hair Keratinisation

Keratinisation:

Keratinisation of the human hair structure and its relevance to how it effects
hair colour is most important, keep it foremost in your mind if you are about

to colour hair. What is Keratinisation? As hair grows out of the scalp, the

hair is soft for about six to eight weeks, and then the atmosphere begins to

harden all the cells. The easiest way to actually see Keratinisation is to look
at your finger nails, the white half moon cuticle is soft new nail that has not

yet been Keratinised, whereas, the rest of the nail has hardened through

Keratinisation.

Also, as our skin cells come to the surface they harden through

Keratinisation, and then flake off into the atmosphere.

So what does Keratinisation have to do with hair colour? If you are taking

hair colour darker it is not a problem, However, if you are lightening hair and
you apply bleach or hair dye all over at once from roots to ends in one single

application, you will notice that the roots lift in colour immediately, the

middle lengths lift less and the ends hardly lift at all, leaving the hair with
three bands of colour.

Be aware of keratinisation and colour in the following way, first apply the

bleach or hair dye to the middle lengths and ends, wait twenty minutes and
then apply fresh bleach or hair dye to the roots and comb it through. Then

the colour will be even from root to ends. (Fig1.)

However, keratinisation is not an issue with the Colour College London
training strips; because, the softer un-keratinised root area of the human hair

training strips has been removed in the wefting process.

The Colour College London training strips are fully keratinised to ensure an

even colour development the entire length of the training strip. Just mix the

provided formula’s and apply the full length of the training strip for a perfect
target colour every time.
