The study evaluated the effectiveness of microneedling for treating alopecia areata in 20 participants aged 11 to 45 years. Weekly sessions over 8 weeks, with a 12-week follow-up, showed significant hair density and growth improvements. Specifically, 55% of patients experienced 75-100% hair regrowth, and 25% had 50-74% regrowth. Dermoscopic analysis indicated a reduction in alopecia markers and an increase in terminal hair. No significant adverse effects were noted, except for temporary discomfort. The study concludes that microneedling is a promising treatment for hair regrowth in alopecia areata, though further research with larger sample sizes is advised.
