How is a hair formed?
Each hair develops from a group of epidermal cells at the base of a tubelike depression called a hair follicle, which extends from the surface into the dermis and contains the hair root. The epidermal cells at the base are nourished from dermal blood vesssels in a projection of connective tissue at the deep end of the follicle. As these epidermal cells divide and grow, older cells are pushed toward the surface. The cells that move upward and away from the utrient supply become keratinized and die. Their remains constitute the structure of a developing hair shaft that extends away from the skin.
