TLDR All types of Platelet-Rich Plasma (PRP) can treat hair loss, but homologous PRP works best due to its higher platelet count and growth factors from multiple donors.
The study conducted between 2014 and 2015 compared the effectiveness of nonactivated platelet-rich plasma (n-PRP), activated autologous PRP (a-PRP), and homologous PRP (h-PRP) in treating androgenic alopecia in male patients. The results showed that all types of PRP were effective, but h-PRP led to a greater increase in hair density than a-PRP. This was attributed to h-PRP having a higher platelet count and containing growth factors from multiple donors, potentially creating a synergistic effect. The study suggested that the efficacy of PRP in treating androgenic alopecia is primarily due to the growth factors it contains, rather than the number of injections.
