Hair is a filament that grows from a hair follicle in the dermis of the skin. It consists mainly of tightly packed, keratin-filled cells called keratinocytes. The human body is covered with hair follicles except for a few areas, including the mucous membranes, lips, palms of the hands, and soles of the feet.Many growth factors and receptors important during hair follicle development also regulate hair follicle cycling. 3,4 The hair follicle possesses keratinocyte and melanocyte stem cells, nerves, and vasculature that are important in healthy and diseased skin. 5-7 To appreciate this emerging information and to properly assess a patient with hair ...

When it contracts it causes the hair to stand erect, and a "goosebump" forms on the skin. Hair Follicle The hair follicle is a tube-shaped sheath that surrounds the part of the hair that is under the skin and nourishes the hair. It is located in the epidermis and the dermis. Hair Shaft The hair shaft is the part of the hair that is above the skin.

The reticular layer also contains hair follicles, sweat glands, and sebaceous glands.

In the hair follicle, cells undergo a variety of differentiation processes, mostly depending on their layers and positions therein, and electron microscopy reveals a very complex architecture.
