Answer

The natural history of alopecia areata is unpredictable. Most patients have only a few focal areas of alopecia, and spontaneous regrowth usually occurs within 1 year. Estimates indicate less than 10% of patients experience extensive alopecia and less than 1% have alopecia universalis. Patients with extensive long-standing conditions are less likely to experience significant long-lasting regrowth.
