A Prospective and Comparative Study to Explore the Effects of Platelet-Rich Plasma in Hair Transplantation for Patients With Androgenetic Alopecia.

[BACKGROUND] Androgenetic alopecia (AGA) is the most prevalent type of hair loss. Traditionally, treatment for AGA has primarily involved the topical application of minoxidil in conjunction with oral finasteride or spironolactone. Recently, platelet-rich plasma (PRP) has emerged as a significant focus of research in hair loss treatment. However, many studies on PRP-assisted hair transplantation have encountered various limitations.

[OBJECTIVE] This study aims to conduct a prospective, comparative clinical investigation to evaluate the therapeutic effects of combining PRP with minoxidil and finasteride/spironolactone as adjuncts to hair transplantation.

[METHOD] From August 2019 to December 2022, we enrolled 30 patients with AGA in the study, randomly assigning them to an experimental group and a control group. The experimental group received drug therapy alongside hair transplantation and underwent PRP injections, whereas the control group received only drug therapy to assist with hair transplantation.

[RESULTS] Prior to surgery, no significant differences in baseline data were observed between the two groups. Following treatment, the experimental group demonstrated significantly improved follicle survival rates, follicle growth rates, and hair strength compared with the control group.

[CONCLUSION] This prospective, comparative clinical study demonstrated that the application of PRP in conjunction with pharmacological support during FUE treatment for AGA resulted in improved follicle survival rates, hair growth rates, and hair strength.
