Alopecia Areata
According to the American Hair Loss Council, alopecia areata also affects (to some degree) millions of men, women and children. This non-scarring, inflammatory condition is usually temporary -- it's experienced in episodes by almost 90 percent of those who have it. Alopecia areata is generally thought to be an autoimmune disease in which cells from an individual's own immune system mistakenly prevent hair follicles from producing hair fiber. In many cases, the body will use its own management system to reverse the problem in time. However, those affected even temporarily by the disease can experience low self-esteem and depression and may need help from their families and friends.
The National Alopecia Areata Foundation says that approximately 20 percent of alopecia areata cases are related to heredity, as opposed to androgenic alopecia, in which heredity plays a more prominent role.

The disorder causes patchy hair loss, often appearing as small, smooth patches on different areas of the scalp (or, occasionally, on other parts of the body). These patches can appear suddenly, sometimes within 24 hours, and some people report feeling tingling and/or pain at the site. Other types of alopecia areata include:
