Hair is composed of cornified threads of cells that develop from the epidermis and cover most of the body. Each hair has a medulla, cortex, and cuticle. The medulla in the center contains soft keratin and air. The cortex, the innermost thickest layer, has the pigment that gives hair color. The cuticle, the outermost layer, has cells that overlap like scales. Both the cuticle and cortex have hard keratin.
The hair root in a hair follicle is embedded beneath the skin. The hair shaft protrudes from the skin. Hair sheds and is replaced constantly during growth and rest phases. Hair has a protective function: eyebrows keep sweat from running into the eyes, nose and ear hairs filter dust from the air, and scalp hairs protect against abrasion and overexposure to sun rays.
Hair follicles extend into the dermis; the deep ends expanded parts are called hair bulbs. A papilla (connective tissue protrusion that contains capillaries) protrudes into the hair bulb and provides nutrients for the growing hair. The hair follicle walls have an inner epithelial root sheath and an outer dermal root sheath. The epithelial root sheath has an inner and an outer layer that thins as it approaches the hair bulb. It becomes the matrix, the actively growing part of the hair bulb that produces the hair.
Different Types of Hair
Before removing hair, it helps to know about the different types of hair on our bodies. All hair is made of keratin, a hard protein that's also found in your fingernails and toenails. Hair growth begins beneath the surface of your skin at a hair root inside a hair follicle, a small tube in the skin.
You have two types of hair on your body. Vellus hair is soft, fine, and short. Most women have vellus hair on their chest, back, and face. It can be darker and more noticeable in some women than others, especially those with darker complexions. Vellus hair helps the body maintain a steady temperature by providing some insulation.
Terminal hair is coarser, darker, and longer than vellus hair. It's the type of hair that grows on your head. Around puberty, terminal hair starts to grow in the armpits and pubic region. On guys, terminal hair begins to grow on the face and other parts of the body such as the chest, legs, and back. Terminal hair is there to provide cushioning and protection.
In some cases, excess hair growth, called hirsutism (pronounced: hur-soo-tih-zum), may be the result of certain medical conditions. In girls, polycystic ovary syndrome and other hormonal disorders can cause dark, coarse hair to grow on the face, especially the upper lip and chin, as well as on the chest, belly, and back. Some medications, like anabolic steroids, also can cause hirsutism.
