Alopecia areata is the sudden and complete loss of hair in coin shaped areas on a hair bearing area of the skin, most commonly the scalp. It is most common in children but can appear up to the age of forty. This is a classic presentation of alopecia areata in a young individual. As you look at the bald area, notice the little black dots which are exclamation point hairs, a hallmark of this disease. This area will regrow without scarring.
