 The study compares the clinical efficacy, dermoscopic results, and safety of triumcinolona setonide, TA, and beta-methasone depropionate, BD, injections at different concentrations in localized scalp and beard alopecia. The results show that BD 1-quarter dilution, 1.25 mg per deciliter, is the best corticosteroid for intralesional injection in the treatment of localized alopecia areata in adults, with similar sixth-month hair regrowth scores and overall treatment success rates as TA 1-quarter dilution, 1.25 mg per deciliter, but with fewer adverse effects.
