Hair Follicle

Diagram of the Structure of the Skin

A hair follicle (hair follicles) are tiny tunnel-shaped features in the epidermis (outer layer) of the skin. Hair starts to form at the base of a hair follicle. As more cells form , the hair extends towards then through the surface of the skin.

More about its structure:

A hair follicle is enclosed by the sheath of epidermal cells and connective tissue that surround the root of a hair. This consists of two layers of epidermal cells, which are called the internal root sheath (see internal epithelial root sheath) and the external root sheath (see external epithelial root sheath). These two layers are surrounded by a connective tissue sheath.

For more detail in a diagram see the structure of a hair follicle.
