PRP stands for platelet-rich plasma. It is a procedure, not a medicine: a nurse or doctor draws some of your blood, spins it in a centrifuge to concentrate the platelets, and injects that concentrate into your scalp in a clinic. PRP therapy has no EU marketing authorisation for hair loss. No doctor in the EU — including ours — can prescribe it, and it cannot be arranged online: you would need to attend a clinic in person. ## Can I get it? We don't offer PRP today, but our doctors can review your case and propose an equivalent hair-growth treatment with EU authorisation. **What can I take instead?** Minoxidil is approved in the EU, has published peer-reviewed trial results, and can be prescribed today if a doctor decides it suits you. See [the minoxidil page](/library/medicines/minoxidil). ## What it is A small amount of your own blood is taken and spun in a machine to concentrate the platelets, and that concentrate is then injected into the scalp in the hope that the growth factors platelets release will act on the hair follicles. Because it is a procedure using your own blood rather than a manufactured medicine, no medicines regulator has authorised it and there is no approved product information — what is injected depends on the individual clinic's equipment and protocol. ## What the studies reported Every study behind PRP for hair loss is listed here with how many people took part and whether the results are peer-reviewed or a company announcement. | Source | What it found | | ------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | *Journal of Cosmetic Dermatology* 2024 — systematic review | Covered 9 studies, 291 participants in total; 7 of the 9 were judged at moderate risk of bias. Authors describe the overall evidence as low quality with high variation between studies, and note there is no standard PRP preparation or injection protocol. | | Zhang et al., *Journal of Cutaneous Medicine and Surgery* 2023 — meta-analysis | 9 randomised trials, 238 patients. Two of the studies reported adverse reactions; none reported a serious adverse reaction. | The published evidence is mixed: several trials report an increase in hair density, but reviewers judge the studies to be small, inconsistent and at risk of bias, and the review's own conclusion is that more standardised, better-controlled trials are still needed. ## What has been reported Reaction data is limited to what the meta-analysis above recorded: 2 of the 9 randomised trials it covered reported adverse reactions after injection, and none reported a serious adverse reaction. ## Available hair-growth treatments A licensed doctor decides case by case. We never prescribe without evaluation. A 5-alpha-reductase inhibitor taken daily. A doctor may prescribe it after reviewing your history and ruling out contraindications. Low-dose oral minoxidil, used off-label by some dermatologists. Requires close medical supervision for potential cardiovascular effects. Solution or foam applied directly to the scalp. Can be combined with other actives in a compounded formulation. A more potent 5-alpha-reductase inhibitor. Reserved for specific cases, always under medical evaluation. ## How Hi-Doctor handles it A licensed doctor reviews your hair-growth questionnaire and proposes one of the EU-authorised options above if it fits your case. See [how the consultation works](/essentials/how-it-works) and [how we handle safety and eligibility](/essentials/safety). Pricing is on [the pricing page](/essentials/pricing). ## Start a consultation Answer the hair-growth questionnaire and a registered doctor reviews it. They decide whether treatment is appropriate, which one, and at what dose — and declining is a normal outcome. See [what it costs](/essentials/pricing) and [how the review works](/essentials/how-it-works). This page is reference information, not medical advice and not a prescription. Whether a medicine is appropriate for you is decided by a registered doctor after reviewing your consultation.
