Role of Growth Factors-Rich Plasma (Activated Platelet-Rich Plasma) in Androgenic Alopecia: Literature Review and Suggested Treatment Protocol

The review discussed the potential of Platelet-rich Plasma (PRP) as a treatment for androgenic alopecia (AGA), highlighting its ability to promote hair growth by enhancing angiogenesis and stimulating hair follicle activity. Despite the variability in PRP preparation methods affecting its efficacy, numerous studies, including those by Singhal et al. (2015), Ayatollahi et al. (2017), and Puig et al. (2016), demonstrated PRP's effectiveness in both male and female pattern baldness. The review proposed a treatment protocol involving multiple PRP injections over several months, showing promising results in hair regrowth and patient satisfaction. However, it concluded that further standardized research is needed to optimize treatment protocols and confirm long-term efficacy.
