Alopecia areata is a disease that attacks your hair follicles (the part of your skin that makes hair). In most cases, hair falls out in small, round patches about the size of a quarter. This causes only a few bare patches. Some people may lose more hair. In only a few people, the disease causes total loss of hair on the head or loss of all body hair.
Your hair may grow back, even if you lose all of it. But it may fall out again. No one can tell you when it might fall out or grow back. You may lose more hair, or your hair loss may stop. The hardest part of the disease is not having these answers.
