Overview

Alopecia areata is an autoimmune disease in which the immune system mistakenly attacks the hair follicles. This can lead to hair loss on the scalp and elsewhere on the body. In most cases, hair falls out in small, round patches on the scalp. Although uncommon, hair loss can be more extensive in some people. This condition can progress to cause total loss of hair on the head (alopecia totalis) or complete loss of hair on the head, face, and body (alopecia universalis). While there is neither a cure for nor drugs approved for treatment, some people find that medications approved for other purposes can help their hair grow back.[1]
