Topical minoxidil (3%) in extensive alopecia areata, including long-term efficacy

The study evaluated the efficacy and safety of 3% topical minoxidil in treating extensive alopecia areata. The treatment was well-tolerated with few side effects, and after one year of treatment, 60% of the patients had cosmetically acceptable hair growth. Patients with less than full scalp involvement at baseline had a higher chance of experiencing hair growth, with 65% of patients experiencing either incomplete or cosmetically acceptable hair growth. The study suggests that topical minoxidil may be a safe and effective treatment option for extensive alopecia areata.
