A Randomized Prospective Study to Evaluate the Efficacy of Various Topical Treatment Modalities in Patients with Alopecia Areata

The study evaluated the efficacy of various topical treatments for alopecia areata (AA) in 100 patients over 12 weeks. Patients were randomly assigned to four treatment groups, and outcomes were measured using the Alopecia Grading Scale (AGS) and Regrowth Score (RGS). Results indicated that Group A, treated with 0.05% betamethasone dipropionate, showed the most significant clinical improvement, while Group D had the poorest response. Groups B and C had intermediate responses. The study concluded that 0.05% betamethasone dipropionate was the most effective treatment for patients with patchy AA involving less than 25% hair loss.
