Leukocyte-rich and leukocyte-poor PRP differ in white-blood-cell content. For hair treatment, current evidence is not strong enough to choose a universally better option from that label alone. The diagnosis, complete preparation, procedural care and review plan remain more useful than a simple rich-versus-poor ranking.

What are leukocytes doing in the discussion?
Leukocytes are white blood cells. Different PRP preparation methods retain different amounts of them alongside platelets and plasma. White cells are involved in immune and inflammatory processes, which makes their presence relevant to research. That does not make all white cells harmful or all low-white-cell preparations superior.
The 2025 alopecia meta-analysis found that inconsistent or missing reporting prevented a reliable assessment of leukocyte content on efficacy and safety. This is a gap in the evidence, not evidence that the choice never matters.
Why can joint PRP evidence not settle a hair question?
A knee joint and a scalp are different treatment settings, with different diseases and outcome measures. A recommendation developed for one tissue should not be transferred automatically to another. The phrase leukocyte-poor may appear in joint research without establishing the best hair protocol.
When comparing claims, ask which condition was studied and whether the preparation and outcomes match the proposed treatment. Evidence for pain in osteoarthritis does not answer a question about hair density in androgenetic alopecia.
What does the major hair review allow us to say?
The 2025 review found density benefit in relevant pooled comparisons, but substantial variation between trials. Reporting of composition was often incomplete, so the authors could not determine the effect of leukocyte inclusion. A pooled PRP benefit therefore cannot be assigned confidently to one white-cell label.
The 2026 preparation review also describes the lack of a standardised PRP protocol. These sources support asking for transparent documentation. They do not support claiming that one label guarantees less inflammation, better growth or a shorter course for every patient.
Discuss your priorities and the appropriate appointment. The team will confirm suitability, availability and the complete fee before booking.
Does leukocyte-poor mean inflammation-free?
No. An injection procedure can cause discomfort, redness, bruising or swelling even when the preparation contains fewer white cells. Tissue response depends on more than one component. A description of the sample cannot remove the need for consent, sterile technique and clear aftercare.
Ask the clinician which reactions are expected, which symptoms need advice and how to contact the service afterwards. Severe or worsening symptoms should not be dismissed because the treatment was described as natural or low-inflammatory.
What should a clinic be able to explain?
Ask what the preparation label means in its protocol, whether composition is measured or inferred and how the approach relates to evidence for your diagnosis. It is acceptable for a clinician to explain where evidence is limited. A confident-sounding answer is not a substitute for a relevant study.
Also ask about the baseline record, the review point and the practical alternatives. This article does not assert a particular white-cell composition for our preparation; individual procedural details should be confirmed at consultation.
How do I keep the decision focused on my goals?
Describe the change you want to address and what would make a course worthwhile. Discuss previous treatment, tolerance for procedures, uncertainty and the total cost. Agree how progress will be assessed using consistent records rather than changing the definition of success at each visit.
If the diagnosis is unclear, resolve that first. PRP evidence for pattern hair loss should not become a reason to inject an inflamed scalp or delay assessment of scarring disease. The useful decision is whether a documented plan fits you, not which preparation label sounds most advanced.
What makes a premium PRP consultation worthwhile?
The value is in a diagnosis that fits your hair loss, an explanation of the relevant evidence and a documented plan with a review point. Ask how the clinician records the baseline, what alternatives deserve consideration and how a disappointing response would be handled. A technical label should be explained in plain language, with a clear distinction between how a preparation is made and what it has been shown to achieve.
For published London market context, Harley Street Skin Clinic lists lead-doctor hair PRP at £900 for one session or £2,440 for three. Those are that clinic's prices, not The London PRP Clinic's fees, and the services are not assumed to be equivalent. Price does not prove clinical superiority. Ask our team for the complete individual quote, the proposed number of visits, review arrangements and any later maintenance decision before you commit. No treatment response is guaranteed.
What should I bring to an assessment?
Bring a timeline of hair changes, previous treatment, dated photographs and a list of medicines and supplements. Mention pain, redness, scale, sudden shedding or patchy loss, because these can change the diagnostic pathway. Do not stop prescribed treatment to prepare for an enquiry. The clinician should establish whether PRP is relevant before agreeing a course and explain when another type of care is more appropriate.
