Human pubic hair, coloured scanning electron micrograph (SEM). Notice the flattened nature of this type of human body hair. Pubic hair is a type of body hair found in the genital area of adolescent and adult humans. The outer layer of hair (the cuticle) has overlapping scales of keratin. These scales are thought to prevent hairs from matting together. Hair is made up of a fibrous protein called keratin. Internally the hair shaft is divided into three concentric sheaths (layers) called the medulla, cortex and outer cuticle. Hair is non-living tissue. Hair grows from a hair root (bulb) embedded in the skin. Hair growth occurs when epidermal cells divide at the base of the root bulb. Hair is non-living tissue.
