Alopecia Areata (AA) is an autoimmune disease that causes hair loss in well-defined patches, with a lifetime risk of 1.7% in the general population. The disease often begins before the age of 20, affecting up to 60% of patients. The hair loss is typically localized to a single round or oval patch on the scalp, often accompanied by "exclamation point hairs" at the lesion's periphery. Due to a high rate of spontaneous recovery, particularly in cases with small areas of hair loss or recent onset, not all patients require pharmacological treatment. A "watch-and-wait" approach is often recommended, with psychological support provided if necessary. For those seeking active treatment, topical corticosteroids and minoxidil were the preferred options. Novel treatments such as Interleukin (IL)-31 antibodies and 308-nm Excimer laser therapy showed promise. The document also discussed recent patents related to alopecia treatment.
