Background: Androgenetic alopecia (AGA) is the most common form of hair loss in adults, which is generally progressive in the absence of treatment. As a head full of healthy hair adds to the cosmetic appeal of the individual, the consequences of AGA are predominantly psychological. Currently, topical minoxidil is the first-line treatment for AGA. Many adjuvant treatment modalities have been used synergistically with minoxidil. Microneedling is one among such adjuvant treatments, which works by various mechanisms to stimulate the dermal papillary cells that play a key role in hair growth. Aim: To compare the efficacy of microneedling along with topical minoxidil and topical minoxidil alone in the treatment of AGA in men. Materials and Methods: Sixty-eight men with Norwood–Hamilton grade III and IV AGA were recruited for the study. After randomization, one group was treated with weekly microneedling and twice daily application of 5% minoxidil solution and the other group was treated with twice daily application of 5% minoxidil solution alone. Global photographs were taken at baseline (pretreatment) and at end of the study duration. Trichoscopic images were taken from a targeted fixed area before treatment (baseline) and at end of the therapy from where hair count was also carried out. The two primary efficacy parameters were assessed: increase in the hair count from that of the baseline and patient self-assessment of hair growth at the end of the study. Results: The mean increase in hair count in the targeted area of one square inch at the end of the treatment was significantly greater for the combination treatment group (12.52/inch2) compared to that for the minoxidil alone group (1.89/inch2). Four patients in the "microneedling plus topical minoxidil" group reported a 50% improvement versus none in the "minoxidil alone" group. Conclusion: Our study showed that the combination of microneedling and topical minoxidil treatment was superior compared to topical minoxidil alone with regard to increase in the hair count and patient satisfaction, although the response achieved was not cosmetically significant.
