Human hair. Scanning electron micrograph (SEM) of human hairs emerging from the epidermis (outer layer of skin). Hairs are made up of dead tissue. The outside of the hair, the cuticle, is covered in overlapping scales that protect the hair's central cortex, which is made up of the fibrous protein keratin.
