TLDR Platelet-rich plasma (PRP) can help restore hair, but the best method for preparing and using it is still unclear.
The document reviews the therapeutic role of Platelet-rich plasma (PRP) in hair restoration. PRP is an autologous substance created from the centrifugation of patients' own blood, and it has gained popularity as a minimally invasive hair restoration technique. The review includes 56 unique original studies with 2,114 unique patients. The studies show that PRP has a therapeutic role in hair restoration, with multiple treatments at 4-week intervals being recommended. Most studies used an activator and found some benefit to double-centrifugation. However, there is still a significant gap in knowledge regarding a defined, evidence-based, and standardized preparation technique for PRP use in hair restoration. All of the included studies called for the need for further rigorous, randomized double-blinded trials assessing PRP and hair restoration.
