Response to Microneedling Treatment in Men with Androgenetic Alopecia Who Failed to Respond to Conventional Therapy

This document is a case series that examines the use of microneedling as a treatment for androgenetic alopecia (AGA) in men who did not respond to conventional therapy. The study included four men who had been on finasteride and minoxidil for 2 to 5 years without experiencing new hair growth. These men underwent microneedling treatment in addition to their ongoing therapy for 6 months. The results showed that all patients had a positive response, with new hair growth starting after 8-10 sessions. Three patients reported more than 75% satisfaction with their hair growth, while one patient reported more than 50% satisfaction. These results were sustained during the 18-month follow-up period. The study concludes that microneedling can be an effective treatment for promoting new hair growth in men with AGA who do not respond well to conventional therapy.
