Overview
Alopecia areata is a condition in which the body attacks its own hair cells, causing hair loss. The hair loss can be total (including facial hair such as the eyelashes and eyebrows) or partial, resulting in a bald spot. Any disorder in which the body attacks its own cells is called an autoimmune disorder, and alopecia areata is an example of this kind of disorder. In general, autoimmune disorders are poorly understood, and there is rarely treatment for them; fortunately, those affected by alopecia areata sometimes experience regrowth of the hair. Though there is no certain treatment for hair loss, your doctor can help with keeping the skin healthy. Alopecia areata is not a contagious condition. This condition runs in families and can be worse depending on the season. There are a variety of reasons for a person to develop hair loss, and it is important to discuss your concerns with your doctor.
