Alopecia Areata

📖What is Alopecia Areata?

Alopecia Areata is an autoimmune condition in which the immune system mistakenly attacks hair follicles, causing sudden, patchy hair loss typically on the scalp but sometimes affecting eyebrows, eyelashes, or other body hair. Unlike pattern hair loss, it often appears as well-defined round or oval bald patches that can develop rapidly over days to weeks. The condition follows an unpredictable course, with hair sometimes regrowing spontaneously in one area while new patches appear elsewhere. In more severe forms, it can progress to complete scalp hair loss or loss of all body hair.
