September is Alopecia Areata Awareness Month. Wear Blue!
Alopecia areata is a common autoimmune skin disease, causing hair loss on the scalp, face and sometimes on other areas of the body. In fact, it affects as many as 6.8 million people in the U.S. with a lifetime risk of 2.1%.
People of all ages, both sexes and all ethnic groups can develop alopecia areata. It often first appears during childhood and can be different for everyone who has it.
