Intralesional Betamethasone Versus Triamcinolone Acetonide in the Treatment of Localized Alopecia Areata: A Within-Patient Randomized Controlled Trial

The study compared the effectiveness of intralesional betamethasone versus triamcinolone acetonide in treating localized alopecia areata through a within-patient randomized controlled trial. The results indicated that both treatments were effective in promoting hair regrowth, but triamcinolone acetonide showed a slightly higher efficacy. The trial involved a significant number of participants, enhancing the reliability of the findings. The study concluded that while both treatments are viable options, triamcinolone acetonide may be preferred for slightly better outcomes in hair regrowth.
