Background: Platelet-rich plasma (PRP) is a simple and safe procedure, which has been used for soft tissue and wound healing. PRP has been used in dermatology for skin rejuvenation and alopecia. Objective: The objective of our study was to study efficacy of PRP with microneedling in patients with androgenetic alopecia (AGA) and to assess number of sessions required for a patient. Materials and Methods: Sixty patients diagnosed with AGA were studied between August 2016 and October 2018 who did not respond to minoxidil and finasteride. PRP was prepared by centrifugation of patients’ blood. PRP with microneedling was done for all patients under aseptic conditions. Four to six sessions were done at an interval of 4 weeks. Subjective and objective scores were assessed based on a visual analog global score. Assessment was done at the first session, every next sitting, and 4 weeks after the last sitting. Follow-up was done at 3rd and 6th month after the last sitting. Results: According to subjective scores, two patients (3.33%) had excellent results, 24 (40%) very good, 22 (36.6%) good, 6 (10%) fair results, and 6 (10%) did not have any response. Objective assessment scores showed that two patients (3.33%) had excellent results, 26 (43.3%) very good, 21 (35%) good, 7 (11.6%) had fair results, and 4 (6.7%) did not have any response. Fifty patients underwent four sessions out of which 40 (i.e. 66%) patients had very good results. Only 10 patients required more than four sessions to achieve good results. Patients were happy with four sessions. There were no side effects noted either during or after the treatment. Conclusion: This study shows PRP with microneedling as an efficacious treatment for AGA and augments the effects of conventional treatment. This study sets example for assessing the number of PRP sessions. A minimum of four sessions is required to achieve very good results.
