Abstract. Nearly 50 years ago, Chase published a review of hair cycling in which he detailed hair growth in the mouse and integrated hair biology with the biology of his day.

The Growth Cycle. The hair on your scalp grows less than half a millimeter a day. The individual hairs are always in one of three stages of growth: anagen, catagen, and telogen. Stage 1: The anagen phase is the growth phase of the hair. Most hair spends several years in this stage. The hair follicle consists of a hair shaft and bulb. It is a down growth of the epidermis, with its long axis usually traveling obliquely through the skin layers.

Figure 13.4.1 13.4. 1: dyed hair. 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.

The Hair Follicle Bulge. Hair follicle stem cells are cells with the potential to generate new hairs and potentially even other tissue types as well.
