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.
