Alopecia, otherwise known as alopecia areata, is thought to be an autoimmune disorder in which the hair falls out in small patches. It affects roughly 7 million people in the US alone. At first, the hair loss may be unnoticeable however, if the patches connect, it becomes more obvious. Various parts of the body can be affected, including the scalp, face, and extremities.
Alopecia can develop at any age, in both sexes, and across all ethnic groups. It often first appears during childhood but can be different for everyone. While the hair loss can be unpredictable, it usually appears as a round or oval bald spot on the scalp. Regrowth can occur with or without treatment, and the new hair growth may fall out again leading to frustration and low self-esteem for anyone with this condition.
