PRP — Platelet-Rich Plasma — is often described as a 'natural' hair loss treatment, but the term hides a lot of specifics. Here's what actually happens in a PRP session, what the evidence says, and who it genuinely works for.
The process: a small sample of your blood is drawn from your arm, then spun in a centrifuge to separate the platelet-rich plasma from the rest of the blood. Platelets naturally contain growth factors that trigger cell regeneration and repair. This concentrated plasma is then reinjected — via a series of tiny injections — into the scalp (for hair loss) or face (for skin regeneration).
For hair loss, the growth factors stimulate dormant hair follicles, extend the growth phase of active hairs, and encourage thicker, healthier regrowth. The clinical evidence is strongest for early-to-moderate androgenetic alopecia (male and female pattern hair loss) and for post-partum shedding. It also helps with hair thinning caused by stress, iron deficiency, or hormonal shifts.
Where PRP is less effective: advanced hair loss where follicles are no longer active — no treatment can regrow hair from a follicle that has completely died. If large sections of your scalp are already bald, PRP is unlikely to restore density there, though it can protect the surrounding hair.
Timeline: results are gradual. Most patients see reduced shedding within 4–6 weeks, thicker hair in existing areas by month 3, and new growth developing over 3–6 months. A course of 3 sessions spaced 4–6 weeks apart is typically recommended, with a maintenance session every 6–12 months after that.
Because PRP requires an accurate diagnosis of your specific hair loss pattern to work well, we always start with a consultation. Book one at ANNS and we'll give you an honest assessment — including whether PRP is right for your situation or whether another approach would serve you better.
