PRP Combined With Botulinum Toxin Type A Injection for the Treatment of Androgenetic Alopecia: A Study

Research Purpose The objective of this study is to determine the safety and efficacy of combined PRP and BTX-A injection therapy for Androgenetic Alopecia (AGA). Study Content This clinical trial is a randomized (1:1), multicenter, parallel-group, controlled study. AGA patients aged 18 to 60 years presenting to the participating centers will be recruited. After providing informed consent, eligible patients who meet the inclusion/exclusion criteria will be randomized in a 1:1 ratio, with separate randomization schedules for male and female patients, into either the experimental group (PRP combined with BTX-A injection) or the control group (PRP injection only). A total of 76 patients will be enrolled. Control Group: Subjects randomized to the control group will receive PRP injection therapy. The PRP will be administered intradermally (at a depth of approximately 1.5-2.5 mm, with injection points 1 cm apart) into the scalp area (defined as ≥12 cm from the lateral canthus and ≥9 cm from the top of the ear, encompassing the frontal, temporal, parietal, and occipital regions) at a dose of 0.1 ml/cm². The treatment regimen consists of monthly injections, 4 ml per session, for a total of 3 consecutive sessions. Experimental Group: Subjects randomized to the experimental group will receive injections using the same method and frequency as the control group. For the first session, the injection will consist of 100U of BTX-A reconstituted in 4 ml of PRP. The second and third sessi…
