(credit: modification of work by “kilbad”/Wikimedia Commons).Hair is a component of the integumentary system and extends downward into the dermal layer, where it sits in the hair follicle. Humans have approximately five million hair follicles, which offer protection from cold and UV radiation, produce sebum, and can have a significant psychological impact when growth or structure is unbalanced.[1]

Overview. At the base of the hair follicle are sensory nerve fibers that wrap around each hair bulb. Bending the hair stimulates the nerve endings allowing a person to feel that the hair has been moved. One of the main functions of hair is to act as a sensitive touch receptor.

The hair follicle undergoes cyclical rounds of quiescence (telogen), growth (anagen) and regression (catagen), and consists of heterogeneous compartments (labeled A–E). In the present report, we demonstrate label-free visualization of hair follicle stem cells in mouse whiskers by multiphoton tomography due to the intrinsic fluorophores such as NAD(P)H/flavins. We compared multiphoton tomography of GFP-labeled HAP stem cells and unlabeled stem cells in isolated mouse whiskers. Abstract. The epidermis and its appendage, the hair follicle, represent an elegant developmental system in which cells are replenished with regularity because of controlled proliferation, lineage specification, and terminal differentiation.

It can last years for the hairs on your head, while hairs on other areas of the body tend to have shorter anagen periods. During the second phase, catagen, hair growth slows down.
