Alopecia areata is a common form of hair loss where the patient has well defined, usually circular areas of hair loss, mostly on the scalp. Children are mostly affected. The condition can become more widespread to involve the whole scalp (alopecia totalis) or even the whole body(alopecia universalis). This is an outo-immune disease where the body “attacks” its own hair roots.
Treatment of alopecia areata varies from topical corticosteroid creams to oral corticosteroids and even a topical sensitizer.
