The composition of the hair shaft onto which shampoos and conditioners are applied are; keratin, water, lipids, minerals, and pigments (melanin).
The hair shaft is a part of the hair that is situated above the skin. The hair shaft is mostly composed of keratin with water, lipids, minerals and pigments (melanin). The hair shaft contains three layers which are; the cuticle (the thin outer part of the hair shaft), the cortex (the middle part of the hair shaft which is responsible for the texture, strength, and colour of the hair), and the medulla (the deepest part of the hair shaft). The cuticle is the first layer of the hair shaft to be damaged when hair is not treated properly through the use of insufficient shampoo, conditioner, or brushing.
