Alopecia is an autoimmune disease in which the immune system attacks the hair follicles. In alopecia areata, the hair falls out in small, round patches about the size of a quarter. In some cases, people will only have a few bare patches, but in others, hair loss can progress to include the entire scalp (alopecia areata totalis) or the entire scalp, face and body (alopecia areata univeralis).
