Alopecia Areata

Alopecia areata was described as an asymptomatic, nonscarring hair loss condition characterized by spontaneous remissions and exacerbations. Its etiology was unknown, but it was associated with conditions such as vitiligo, atopy, pernicious anemia, Down syndrome, and thyroiditis. The extent of hair loss could vary from localized patches to the entire scalp or body. Treatment was challenging due to individual variability in response, spontaneous remissions, and a high relapse rate. The most common treatment involved intralesional corticosteroid injections, though other methods like systemic steroids, contact allergens, minoxidil, and psoralens with ultraviolet light were also used.
