Microneedling With Triamcinolone Acetonide Versus Intralesional Triamcinolone Acetonide in Treatment of Alopecia Areata

The study compared the effectiveness of intralesional triamcinolone acetonide versus microneedling with triamcinolone acetonide for alopecia areata treatment in 50 patients. The results showed a statistically significant reduction of the SALT score and all dystrophic hair markers of alopecia areata by dermoscopy at the end of the study versus baseline in both groups. However, the difference between the microneedling group and the intralesional group concerning clinical response was statistically insignificant. The study concluded that microneedling, especially when combined with Triamcinolone acetonide, is an effective treatment for alopecia areata, providing a comparatively inexpensive, safe, less painful, less invasive tool with no serious complications.
