Abstract

OBJECTIVE: Platelet-rich plasma (PRP) is widely known as an alternative therapy for androgenetic alopecia (AGA); however, there is no standardized method for its preparation and application. This study aims to compare the thrombocyte count elevation and clinical AGA improvements between single- and double-spin PRP preparation methods. METHODS: This preliminary, double-blind, randomized clinical trial included 30 male subjects with AGA aged 25 to 59 years with Hamilton-Norwood stages III to VI. Subjects were divided into a single-spin group (3,000rpm for 15 minutes) and a double-spin group (first spinning at 1,500rpm for 6 minutes, continuing at 2,500rpm for 15 minutes). The study was conducted for six weeks, with a two-week visit interval. Baseline and PRP thrombocyte counts were assessed on the initial appointment. A total of 1cc of PRP was intradermally injected into a 6×4cm predetermined area, administered at Weeks 0, 2, and 4. At every visit, clinical progress was assessed by overall hair appearance, photography, trichoscopy, and trichoscan. All subjects were instructed to use minoxidil twice daily during the study. This study has been registered at clinicaltrials.gov (ID No. NCT05681897). RESULTS: Both groups increased thrombocyte counts by 4 to 5 times from their initial levels; however, the increase in the single-spin group was more significant. Significant improvements were observed in both groups, including hair density, hair rate, and hair count of anagen, telogen, vellus, and terminal hair. LIMITATIONS: Limitations include lack of placebo or vehicle control. CONCLUSION: Both PRP preparation methods significantly raise thrombocyte counts, substantially improve nearly all hair parameters, and have tremendous therapeutic promise for treating AGA. Clinicians may designate one of the two techniques.
