PRP (platelet-rich plasma) therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed, and then injected into the scalp.
Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
PRP therapy is a three-step process. Most PRP therapy requires three treatments 4–6 weeks apart.
Maintenance treatments are required every 4–6 months.
