• 80% protein
• 10-15% water
• 5-10% pigments, minerals and lipids

Each hair strand is divided into the hair shaft above the skin and the root area below it. 80% of each hair strand is made up of a central cortex. At the very middle of the cortex is the medulla.

Colour comes from…
The tiny keratin protein fibres, which are twisted together to create longer, more stable fibres in the cortex. Your natural colour pigments are stored here.

Shine comes from…
Overlapping layers of ‘keratin’ in the external cuticle that look like roof tiles.  It’s this cuticle which determines how dull or glossy your hair is, so if the ‘tiles’ are laying flat you get shiny hair that’s smooth and if they stick up you get knotted dull hair.
