Patient Satisfaction and Clinical Effects of Platelet-Rich Plasma on Pattern Hair Loss in Male and Female Patients.

Introduction Hair loss is a widespread condition in both genders. Over the past decade, platelet-rich plasma (PRP) has become a common treatment for hair loss. Our goal was to analyze patient satisfaction and the clinical effects of PRP on male and female pattern hair loss. Methods Over a period of 12 months, we treated a total of 56 patients for androgenetic alopecia with PRP. All of these patients were included in this study; 15 cc of whole blood was spun in an ACP double syringe (Arthrex Inc., Naples, Forida) for five minutes. The yielded 5 to 6 cc of PRP were then injected into the scalp. Forty-nine patients were treated with a series of three injections at monthly intervals, three patients with a series of four injections, two patients with a series of five injections, one patient was treated with a series of seven injections, and one patient with a series of eight injections. Follow-ups were conducted one month after the last treatment. A self-drawn questionnaire was used to assess the satisfaction and clinical results from the patient's and the clinician's perspectives. Results The average age was 41 years (20-68 years). Fifty-seven percent of all patients were male and 43% female. In total, the patients were satisfied with the treatment results. The average score was 7.29 on a scale from 0 to 10. The clinician's rating was similar (6.46). Moreover, with an average score of 8 on a scale from 0 to 10, it is very likely that the patients will recommend PRP treatments to friends. The probability of occurrence of clinical effects among the entire study population was reported as follows: improvement in hair density (patient's rating: 64%; clinician's rating: 46%), thickness (38%; 45%), quality (46%; 54%), sheen/lustre (27%; 21%), new hair growth (57%; 68%), less hair loss (48%; 20%), other positive effects (5%, 2%), no effects (4%; 4%), negative effects (0%; 0%). Conclusion Our study revealed encouraging results for the treatment of male and female pattern hair loss with PRP. The autologous treatment was rated with high satisfaction scores and can be considered a safe and effective treatment modality.
