Comparative efficacy of injection triamcinolone acetonide given intralesionally and through microneedling in alopecia areata

Conclusions: ILCSs have been cornerstone in the treatment of limited AA, but depth of injecting drug cannot be controlled, microneedling whereas is an effective drug delivery system and also causes release of growth factors. In this study, injectable TA used intralesionally and topically with microneedling had nearly similar efficacy in causing regrowth of hair with microneedling resulting in a more uniform but less dense regrowth of hair with lesser adverse effects.
