A Brief Study on Alopecia Areata

Alopecia areata (AA) is an autoimmune condition causing nonscarring hair loss on the scalp or body, often presenting as sharply demarcated round patches. It can occur at any life stage and is commonly associated with atopy and autoimmune thyroiditis. Treatments, including topical, systemic, and injectable medications, show varied responses and frequent relapses, highlighting an unmet clinical need. The etiology involves genetic and environmental factors, with recent advancements in genetic research. Treatment options include topical corticosteroids, immunotherapy, and minoxidil. AA can also affect nails and may progress to alopecia totalis or alopecia universalis.
