If the 'bark' of the hair is well looked after the whole hair remains in good condition. If the 'bark' is stripped off to expose the centre the hair may break.The centre part of the hair, called the cortex, makes up most of the hair shaft. It is the cortex that gives hair its special qualities such as elasticity and curl. The cortex is packed with strands of keratin, lying along the length of the hair. These keratin fibres are made of the low-sulphur keratins, and are compressed into http://www.pg.com/science/haircare/hair_twh_14.htm

What keratin forms?
Keratin is formed by the outer layer of the skin. The epidermis, which is on top of the dermis, as a part of layer called the basal layer. This is the growing layer, which pushes out when a new layer forms. As soon as the layer comes closer to the surface it becomes filled with the product called keratin. This layer cells is dead because it cannot be supported this close to the surface. Hair and nails also are formed of keratin and are also formed in the same way. Keratin is made of fibrous polyproteins and so is composed of nitrogen, carbon, hydrogen and oxygen.
Why does hair absorb oil?
Hair is made of proteins, mostly keratin. The cells are no longer vascular, but the outside of the hair shaft is porous, and can absorb water and oil.
