Glossary Alopecia Areata

autoimmune disorder causing patchy hair loss on scalp and body

Alopecia Areata (AA) is an autoimmune condition where the body's immune system mistakenly attacks hair follicles, leading to patchy hair loss on the scalp and other areas of the body. This condition can affect individuals of all ages and often results in round, smooth bald patches, though the extent and pattern of hair loss can vary widely.
