    Hair is a protein made of a follicle, root and bulb. The follicle is deep in the skin & is attached to a tiny sebaceous gland and muscle fiber. Hair grows when the follicle gathers a "bundles" old cells. The sebaceous gland and muscle fiber push the bundles of old cells up through the skin in a root sheath. The sheath has an internal and external layer. The external layer contains RNA that gives the hair its color and texture. The internal layer contains the hair fiber.
