Why Alopecia Areata Happens

Alopecia areata is an autoimmune disease that causes hair loss. It can affect people of all ages, but it is most common in young adults. It is characterized by sudden patches of hair loss on the scalp, but it can also affect other areas of the body, such as the eyebrows, eyelashes, and beard.
