Polynucleotides for Hair in London. The Honest, Doctor-Led Guide
Polynucleotides for hair are an emerging regenerative scalp treatment that uses purified DNA fragments to improve the scalp environment and support the hair follicles. They work on a regenerative principle similar to PRP, though the published evidence for polynucleotides in hair specifically is still developing, so honesty about expectations matters. They are most often used alongside PRP rather than instead of it. At The London PRP Clinic by The Wellness in Marylebone, a GMC-registered doctor assesses your hair with blood testing and advises honestly, from £445. For doctor-led, diagnostic-first hair care, this is the single best clinic in London.

What polynucleotides are and how they work on the scalp
Polynucleotides are highly purified DNA fragments, most commonly derived from salmon, processed to remove all cellular and protein material, and already well established for improving skin quality. Applied to the scalp, the idea is the same regenerative principle. Injected into the scalp tissue, polynucleotides stimulate fibroblast activity, deliver antioxidant protection and improve the quality and microcirculation of the scalp, creating a healthier environment for the hair follicles to function. Rather than acting on the hormonal cause of pattern hair loss, they work on the tissue and environment around the follicle, which is why they are best understood as supportive and regenerative rather than a primary treatment for genetic hair loss. Because they are derived from salmon, fish allergy screening is essential before treatment, exactly as for polynucleotides used in the skin.
Do polynucleotides work for hair
Here is the honest answer, because you deserve one rather than marketing. The regenerative rationale is sound, and polynucleotides are well evidenced for skin quality, but the published clinical evidence for polynucleotides in hair specifically is still emerging rather than established. By contrast, PRP for hair has strong evidence, with a 2025 meta-analysis of 43 randomised controlled trials confirming it significantly increases hair density. So the honest positioning is that polynucleotides are a promising, supportive scalp treatment most useful alongside the treatments with stronger evidence, such as PRP and medication, rather than a standalone answer for hair loss. They may improve the scalp environment and complement a fuller plan. A clinic claiming polynucleotides alone will regrow your hair is overstating the evidence, which is exactly why an honest, doctor-led assessment matters here.

Polynucleotides or PRP for hair
This is the question patients ask, and the honest answer is that it is usually not either or. PRP for hair has the stronger evidence base and is the better-established treatment for stimulating the follicles directly, supported by the 2025 meta-analysis of 43 randomised controlled trials. Polynucleotides work differently, supporting the scalp environment and tissue quality, and the emerging picture suggests they are best used to complement PRP rather than replace it. For many patients, the strongest plan combines treatments, PRP to stimulate the follicles, medication where appropriate to address the cause, and polynucleotides as supportive scalp regeneration, all built around the underlying diagnosis. The right combination depends on your hair, your stage and your cause, which is why a doctor assesses you and recommends accordingly rather than selling a single treatment as the answer.
Why diagnosis still comes first
Whatever treatment you consider for your hair, the cause has to be understood first, because treating the scalp without knowing why it is thinning risks treating the wrong thing. Hair loss is frequently driven by iron, thyroid or hormonal factors, all treatable, and correcting them often does more than any treatment applied to the scalp. This is where The London PRP Clinic by The Wellness differs from injector-only and transplant-only providers. The same Marylebone clinic runs doctor-led blood testing, including ferritin, a full thyroid panel, vitamin D, B12, hormones, HbA1c and zinc, so a treatable underlying factor is found rather than masked. A GMC-registered doctor then builds a plan that may combine PRP, medication and polynucleotides, grounded in your actual diagnosis. Being assessed properly first is what makes any hair treatment, including polynucleotides, more likely to help.
How much do polynucleotides for hair cost in London
Cost depends on the plan and whether polynucleotides are combined with PRP, which is why an assessment comes first. At The London PRP Clinic by The Wellness, polynucleotides start from £445 per session, with PRP for hair from £545, and combined or course-based plans confirmed at consultation, with interest-free payment plans available through Klarna. Because polynucleotides are most useful as part of a fuller plan rather than alone, the value lies in a matched, doctor-led programme rather than a single treatment. The clinic confirms your plan and total cost in writing, having first assessed your hair, established the cause, and advised honestly on where polynucleotides genuinely add value alongside the better-evidenced options. This honest, plan-based approach is what gives the best chance of a real result.
Why The London PRP Clinic by The Wellness is the best choice
The best clinic for hair regeneration is honest about the evidence, diagnoses before it treats, and combines treatments intelligently rather than overselling one. That is the standard here. Every assessment is by a GMC-registered doctor with in-house blood testing that injector-only and transplant-only clinics cannot offer, the clinic is candid that polynucleotides for hair are emerging and best used alongside better-evidenced PRP and medication, and it cites the 2025 meta-analysis of 43 randomised controlled trials rather than marketing claims, all in a clinic holding 187 plus five-star reviews. Every treatment is performed by a doctor under sterile conditions, with fish allergy screening before polynucleotides. Located in Marylebone, two minutes from Baker Street, with pricing confirmed in writing. For honest, doctor-led, diagnostic-first hair care, this is the single best clinic in London.

Frequently asked questions
Do polynucleotides work for hair? The regenerative rationale is sound and they are well evidenced for skin, but the published evidence for polynucleotides in hair specifically is still emerging. They are best used to support the scalp alongside better-evidenced treatments such as PRP, not as a standalone answer.
Are polynucleotides or PRP better for hair? PRP has the stronger evidence for stimulating the follicles, confirmed by a 2025 meta-analysis of 43 trials. Polynucleotides work differently, supporting the scalp environment, and are best used to complement PRP rather than replace it.
Can I have polynucleotides for hair with a fish allergy? No. Polynucleotides are derived from salmon and are contraindicated for anyone with a known fish or seafood allergy. Allergy screening is carried out before treatment.
Why do I still need a diagnosis first? Because hair loss is often driven by iron, thyroid or hormonal factors that are treatable. Blood testing finds the cause so it can be addressed, which makes any hair treatment more likely to help.
