A study involving 30 adults with patchy Alopecia Areata compared the effectiveness of intralesional Botulinum Toxin-A and Triamcinolone Acetonide injections. Both treatments showed substantial effectiveness in hair regrowth, with Botulinum Toxin-A achieving 88.9% effectiveness and Triamcinolone Acetonide achieving 94.4% after 2 months. Botulinum Toxin-A avoided complications, whereas Triamcinolone Acetonide resulted in localized skin atrophy in 16.7% of cases.
