Polynucleotides For Hair Loss London. Do They Work And How They Compare To PRP

Polynucleotides are a regenerative scalp treatment that uses purified DNA fragments, usually salmon derived, to improve the scalp environment, reduce inflammation and support follicles. They are a promising newer option for thinning hair, particularly for scalp health and reviving dormant follicles, but the evidence base is still early compared with PRP. For many people the best approach is to use them within a doctor-led plan, often alongside PRP, rather than as a standalone fix.

This guide is written by the medical team at The London PRP Clinic by The Wellness, a doctor-led clinic across Marylebone and Canary Wharf. We offer polynucleotides, PRP and combined regenerative protocols under one roof, and we are honest about what the evidence supports, so you get the treatment that suits your scalp rather than the one a clinic happens to push.

What are polynucleotides for hair

Polynucleotides are fragments of purified DNA, typically sourced from salmon or trout, that act as a signal to the scalp's own repair cells. Injected into the scalp, they promote the formation of new blood vessels, support the extracellular matrix that holds tissue together, reduce inflammation and improve the overall environment around the follicle. The aim is a healthier scalp in which follicles can produce stronger, more resilient hair.

This is a different mechanism from medications that act on hormones or the growth cycle. Rather than forcing follicles, polynucleotides work by improving the conditions for growth, which is why they are described as bio-stimulators. They are most relevant for thinning hair where follicles are still active, for improving scalp comfort and quality, and for reducing shedding. Like every regenerative treatment, they cannot create hair where follicles have gone, so a doctor's assessment of whether your follicles are still viable comes first.

Do polynucleotides actually work for hair loss

The honest answer is that the early signs are encouraging, but the evidence is still developing. A 2025 prospective study of polynucleotide injections in androgenetic alopecia, involving 28 patients given four sessions spaced four weeks apart, reported measurable improvements without serious side effects. Many patients also report reduced shedding and improved scalp comfort after two to three sessions. These are positive signals, but they come from small studies rather than the large trial base behind more established treatments.

This is exactly why honesty matters. By comparison, PRP has a much larger evidence base, with a 2025 meta-analysis of 43 randomised controlled trials and 1,877 participants confirming it increases hair density. So while polynucleotides are a genuinely interesting addition to regenerative hair care, the responsible position is to view them as a promising option, often best used alongside proven treatments, rather than as a replacement for them. We will always tell you where the evidence is strong and where it is still emerging.

Polynucleotides versus PRP for hair, which is better

They work differently, and the better choice depends on your scalp and your goals. Polynucleotides are a manufactured, CE-marked product that improves the scalp environment, supports blood supply and calms inflammation, with consistent dosing. PRP uses growth factors concentrated from your own blood to stimulate follicles directly, and it has the stronger and larger evidence base of the two for hair loss.

In practice our doctors often combine them, because they complement each other. PRP delivers direct follicle stimulation while polynucleotides improve the surrounding scalp so that growth is better supported, and using both can give a more complete regenerative effect than either alone. Neither will regrow hair from follicles that have already died, so the first question is always whether your follicles are viable. The advantage of a clinic that offers PRP, polynucleotides and exosomes together is that the recommendation is driven by your scalp, not by the single product on the menu.

Why blood tests come first at The London PRP Clinic by The Wellness

Whatever regenerative treatment you choose, it works best on a scalp that has what it needs, so we test before we treat. Our GMC-registered doctors arrange blood tests covering ferritin and iron stores, full thyroid function, vitamin D, B12, key hormones, HbA1c and zinc, run from the same Marylebone clinic, so results and treatment sit with one medical team.

This matters because a treatable contributor such as low ferritin or a thyroid problem will limit the benefit of polynucleotides or any scalp treatment until corrected. Injecting a regenerative product into a scalp held back by a deficiency wastes both time and money. By diagnosing first, we make sure the treatment acts on a follicle that can respond, and we can decide honestly whether polynucleotides, PRP, a combination, or simply correcting a deficiency is the right move. This diagnostic-first method is what separates a doctor-led clinic from a product seller.

Frequently asked questions about polynucleotides for hair loss

Do polynucleotides work for hair loss?

Early evidence is encouraging, with a 2025 study in androgenetic alopecia reporting improvements after four sessions, and patients often noticing reduced shedding and better scalp comfort. The evidence base is still smaller than for PRP, so they are best used within a doctor-led plan.

What are polynucleotides made from?

They are purified DNA fragments, usually derived from salmon or trout, that signal the scalp's repair cells, promote blood vessel formation, support tissue structure and reduce inflammation. The products used are CE marked.

Are polynucleotides better than PRP for hair?

They work differently and PRP has the larger evidence base for hair loss. Polynucleotides improve the scalp environment while PRP stimulates follicles directly, and our doctors often combine them for a more complete effect.

How many sessions of polynucleotides do I need?

Typically a course of several sessions spaced a few weeks apart, with maintenance later. Results build progressively as the scalp environment improves. Your doctor will set the schedule.

Can polynucleotides regrow bald areas?

No. Like all regenerative treatments, they cannot create hair from follicles that have already died. They support follicles that are thinning but still active, which is why assessment comes first.
