  1. A hair follicle is a tube-like structure in the skin that surrounds and produces hair12345. It is located deep in the dermis of the skin and consists of two main layers, an inner root sheath and an outer root sheath3. The hair follicle also contains sebaceous glands that secrete oil to condition the hair4, and cells that create new hair by packing old cells together45. The hair grows out of the skin and reaches the surface as more cells are formed12.
