The follicle is the essential unit for the generation of hair. On average your hair grows about half an inch each. For follicles that produce terminal hairs the hair follicle extends into the deep dermis and sometimes even subcutis.

The hair follicle begins at the surface of the epidermis. This happens because of the production of a hormone called dihydrotestosterone or dht. Bending the hair stimulates the nerve endings allowing a person to feel that the hair has been moved.

Meanwhile follicles producing vellus hairs extend only to the upper reticular dermis. Hair is a derivative of the epidermis and consists of two distinct parts. The hair follicles anagen phase also gets continually shorter.

Hair grows out of the follicles in cycles. A hair follicle is a tunnel shaped structure in the epidermis outer layer. At the base of the hair follicle are sensory nerve fibers that wrap around each hair bulb.

When hair follicles shrink in size causing the hair to look finer its called miniaturization. A single hair follicle is composed of multiple mesenchymal and epithelial cell layers all of them comprise more than twenty different cell populations. This is called the cortex which makes up the majority of the hair shaft.

Hair shaft the innermost layer. Blood vessels nourish the cells in the hair bulb and deliver hormones that modify hair growth and structure at different times of life. This is called the medulla.
