Alopecia areata is an autoimmune disorder that every year affects about one in one thousand adults, and approximately 2 percent of the population will experience an episode during their lifetimes. In AA, the immune system incorrectly attacks the body’s own cells, specifically the hair follicles, leading to loss of hair – usually in patches — on the scalp, face or sometimes other areas of the body. Typically, these bald patches appear suddenly and affect only a limited area. In most cases, the hair grows back within 12 months, although recurrence is common and most sufferers will have several episodes during their lifetimes. A small percentage of patients have persistent hair loss even with treatment. Alopecia Areata has been shown to lead to significant psychosocial impacts in patients, negatively impacting self-esteem, body image, and/or self-confidence.
