HYROLYSED ALPHA-KERATIN INCREASES DERMAL HYDRATION
Hydrolysed alpha-keratin increases the water content of the epidermis by reducing transdermal water loss. The water-hating nature of the amino acids that make up keratin reinforces the waterproof barrier of the outer skin layer. A decrease in water loss increases the volume of the intermediate skin layers (70-30% depth) and this increases the depth of the hair follicle canal.
Keratin cells grow and divide, they are continuously moving up the hair fibre canal from the zone of differentiation into what is known as the zone of keratinisation. Here the cells die and become a unit of keratinised tissue held together by only by disulphide bonds.
An increase in the differentiation zone and hydration means not only do these water-hating amino acids bind together more tightly, but they also have a longer period to align themselves correctly. This leads to an increase in the number of intermediate filaments within the keratin helix before the cell becomes keratinised tissue. Properly bound filaments build a thick and smooth hair fibre with high tensile strength resistant to breakage and damage.
A higher water content enables proteins and enzymes to function more efficiently. It also provides a more efficient means to transport nutrients, hormones and other elements.
