Hair is filamentous biomaterial that grows from follicles found in the dermis. It is composed of protein called Keratin. Each strand of hair is comprised of the Medulla, Cortex & Cuticle. Hair growth begins inside the hair folicle. The only "living” portion of the hair is found in the folicle. The visible hair in the hair shaft has no bio-chemical activity & is considered dead. The base of the root is called bulb, which contains the cells that produce hair shaft. Natural color of hair depends on melanin type two pigments. Hair growth is found everywhere on skin except mucous membrane, glabrous skin - palms of hand, soles of feet, lips etc.
