PRP Versus Intralesional Triamcinolone for Alopecia Areata: Comparative Study

This study compared the effectiveness of platelet-rich plasma (PRP) injections versus intralesional triamcinolone acetonide in treating alopecia areata in 50 patients. Conducted over 12 weeks, the study found that PRP therapy was more effective, as indicated by consistently lower mean SALT scores, suggesting better hair regrowth. The patient group was predominantly male, with a mean age of onset at 26.87 years, and most cases involved the scalp. The study highlights PRP as a superior treatment option for alopecia areata compared to triamcinolone acetonide.
