Definition: Alopecia areata is an autoimmune disease that causes hair loss in round or oval patches, usually on the scalp. It can also affect the beard, eyebrows, eyelashes, or any hair-bearing part of the body.
Causes: In alopecia areata, the immune system attacks the hair follicles, causing hair loss. The exact reason for this is unknown, but genetics may play a role.
Pros of Treatment: Treatment can promote hair regrowth, although not always complete.
Cons of Treatment: Corticosteroid injections, topical medications, and light therapy are common treatments, but results can vary and side effects may occur.
Alternatives: There is no cure for alopecia areata. Some people experience spontaneous hair regrowth without treatment.
Recovery Time: Hair regrowth is unpredictable. In some cases, hair may grow back within months, while others may experience permanent hair loss.
