Alopecia Areata is an autoimmune disorder which results in sudden, non-scarring hair loss, often in circular patches on the scalp. Alopecia Areata affects children and adults across all ages, races, and sexes. Each case of alopecia areata is different — sometimes, hair grows back but falls out again later (cyclical) and for others, hair grows back completely and remains.
Alopecia Areata can present in 3 distinct forms: 1. Alopecia Focalis (AF), - Patchy hair loss on the scalp, often circular. Also known as patchy alopecia and the most common form of alopecia areata. 2. Alopecia Totalis (AT) - Total hair loss on the scalp 3. Alopecia Universalis (AU) - Complete hair loss on scalp, face, and body
