Follicle, hair
: A sac from which a hair grows and into which sebaceous (oil) glands open. The follicle is lined by cells derived from the epidermal (outside) layer of skin. "The human hair follicle is a dynamic structure that generates hair through a complex and exquisitely regulated cycle of growth and remodelling governed by numerous genes" (Siobhán A. Jordan, in Molecular Medicine Today).
