Quick answer: PRP (platelet-rich plasma) can help support hair-follicle health and slow thinning in appropriate candidates, especially in earlier-stage loss. It uses growth factors from your own blood and is typically done as a series. It’s not a cure or a replacement for a transplant in advanced loss — candidacy and realistic expectations are set at consultation.
What PRP is
PRP concentrates the growth-factor-rich platelets from a small sample of your own blood, which is then applied to the scalp to support follicle health. Because it uses your own blood, it’s a natural, in-office treatment.
Who it helps most
PRP tends to help most in earlier-stage thinning where follicles are still active. It can support and strengthen existing hair, but it won’t regrow hair where follicles are gone — that’s where a transplant comes in.
What to expect
PRP is typically done as a series of sessions with maintenance over time. Results vary and build gradually. An honest evaluation sets realistic expectations and confirms whether PRP, a transplant, or both fits your situation.
