False-colour scanning electron micrograph (SEM) of a clean human hair. Hair is a fibrous protein (keratin) which develops out of a tubular follicle located in the epidermis of the skin. The external surface of a normal hair consists of overlapping scales, as seen here. Magnification: x130 at 35mm size, x200 at size. BW equivalent is P720/072.
