Per the National Alopecia Areata Foundation:

"Alopecia areata is a common condition that results in the loss of hair on the scalp and elsewhere. It usually starts with one or more small, round, smooth patches. It occurs in males and females of all ages, but young persons are affected most often."

"Modern immunological research is showing that alopecia areata is probably an autoimmune disorder, one in which the body forms antibodies against some part of the hair follicle (a type of "self-allergy").
