PRP with low platelets: who can still have it, and who should wait

Reviewed by The Wellness Team. Last reviewed October 2026.

Short answer: a mildly low platelet count does not automatically rule out PRP. The clearest guidance comes from a 2025 international consensus by the GRIIP (International Research Group on Platelet Injections), which rated the evidence across 31 experts. It states that a significant blood count abnormality should be investigated before PRP, but that previously investigated thrombocytopenia above 50,000/mm3, excluding blood cancers, is not a contraindication. Blood cancers that are active or not stabilised are a contraindication unless a haematologist specifically agrees.

Why platelet count matters for PRP

PRP is made from your own blood. A sample is spun in a centrifuge to concentrate the platelets, and that concentrate is injected back into the scalp or joint. The platelets are the active ingredient, so the starting count affects the dose in the final injection. A lower baseline count can mean a weaker concentrate, which is one reason a proper clinic checks your blood before treating you, rather than after.

What the 2025 consensus actually says

The GRIIP panel, which included haematologists, oncologists and musculoskeletal specialists, rated 23 recommendations. The relevant ones for platelet counts:

1. Investigate first. Any significant abnormality in the blood count should be investigated before a PRP injection. A low count that has never been explained is a reason to pause, not a reason to inject.
2. Mild, investigated thrombocytopenia is not a barrier. A platelet count above 50,000/mm3 that has been investigated and is not linked to a blood cancer is not a contraindication, in the panel's strong agreement.
3. Active or unstabilised blood cancers are a barrier. PRP should not be performed while a haematological malignancy is under diagnosis or not considered stabilised, except in exceptional situations agreed with the haematologist.
4. Remission changes the picture. For people in remission after treatment, or whose haematologist considers the condition cured, PRP may be performed if the platelet count is normal. For stabilised chronic myeloid conditions, the panel requires the haematologist's agreement first.

The panel graded most of these recommendations Grade D, meaning they rest on expert opinion rather than large trials, because almost no trial data exists for these groups. That is the honest state of the science.

What this means in practice

• A mildly low count that your GP already knows about, with a normal explanation, usually does not stop treatment, though we would still confirm it on a fresh blood count.
• A newly discovered low count means we investigate first. We would rather delay an injection than treat through an unexplained result.
• A history of blood cancer means a conversation with your haematologist before any booking, and we will not proceed without it.

What we check before treating anyone

Every PRP treatment at our clinic starts with a consultation and, where indicated, blood tests, because eligibility is a medical question, not a sales question. If you have a known platelet or blood condition, tell us at the enquiry stage and we will say plainly what the next step is, including when the answer is "not yet" or "not at all".

A hair consultation with trichoscopy is £150. If PRP follows, hair PRP is £450 per session or £1,215 for a course of three, and joint PRP is £750 per session, ultrasound guided. Our PRP joint injection cost and booking guide sets out what is included.

Frequently asked questions

Can I have PRP with low platelets? Often, yes. The 2025 GRIIP consensus says previously investigated thrombocytopenia above 50,000/mm3, excluding blood cancers, is not a contraindication. An unexplained low count should be investigated first.

Will low platelets make PRP less effective? Possibly. PRP works by concentrating your platelets, so a lower starting count can mean a lower final dose. That is worth an honest conversation before you pay for treatment, and it is one reason we check bloods first.

I have had a blood cancer. Can I ever have PRP? Sometimes. The consensus says PRP may be performed when a haematologist considers the condition cured or in remission and the platelet count is normal, with specialist agreement for stabilised myeloid conditions. Active or unstabilised disease is a contraindication.

Do you test platelets before treatment? Where indicated, yes. A consultation plus targeted blood tests comes before any injection, so eligibility is settled before money changes hands.
