PRP Hair Treatment UK: Complete Guide to Platelet-Rich Plasma
What PRP actually does, who it works for, the protocol we use at Vinci, honest cost ranges, and what the clinical evidence says in 2026. Reviewed by our medical team.
Platelet-Rich Plasma (PRP) therapy is an in-clinic injectable treatment that uses the patient’s own blood to stimulate hair growth. It is non-surgical, takes 45–60 minutes per session, and has become one of Vinci’s most requested non-surgical treatments — particularly among women with diffuse thinning and men who want to delay or complement transplant surgery.
PRP is not a miracle cure. It does not re-grow hair in a fully bald scalp. But for the right patient — early-stage thinning with viable follicles still present — the published evidence supports meaningful density and thickness improvements.
What is PRP?
Platelet-Rich Plasma is a concentrated fraction of your own blood. A standard 15–20 ml venous draw is spun in a medical-grade centrifuge, which separates the blood into red cells, plasma, and a thin platelet-rich layer known as the “buffy coat.” That concentrated platelet layer is drawn into a fine needle and injected into the scalp at the level of the hair follicle.
Platelets are the body’s natural signalling cells. They contain growth factors — including PDGF, VEGF, FGF, and IGF-1 — which, when concentrated and delivered locally, stimulate follicular activity and extend the anagen (growth) phase of the hair cycle.
How PRP works on hair follicles
- Extends the anagen phase. Growth factors push follicles to remain in the active growing phase for longer, increasing total hair density over time.
- Stimulates dermal papilla cells. The “engine room” of each follicle becomes more metabolically active, producing thicker hair shafts.
- Improves local microcirculation. VEGF drives new capillary formation around follicles, improving oxygen and nutrient delivery.
- Reduces follicular inflammation. Chronic low-grade scalp inflammation (common in androgenetic alopecia) is modulated by PRP’s anti-inflammatory signalling.
Who is PRP for?
PRP works best when follicles are still alive — thinning, yes, but not gone. Strong candidates include:
| Candidate profile | Why PRP suits them |
|---|---|
| Early male pattern baldness (Norwood 2–3) | Preserves and thickens existing hair; delays need for surgery |
| Female diffuse thinning | Addresses the most common female pattern; improves parting density |
| Post-partum hair loss | Accelerates recovery once hormonal cycle restabilises |
| Post-transplant enhancement | Improves graft survival and stimulates neighbouring native hair |
| Early-stage telogen effluvium | Supports recovery from shedding episodes |
| Stable alopecia areata (non-active) | Supports regrowth once condition is quiescent |
PRP is not appropriate for patients on active chemotherapy, those with platelet disorders or anticoagulant use without medical clearance, scarring alopecias, or fully bald areas (Norwood 6–7) with no residual follicle activity.
Vinci’s PRP protocol
Vinci uses a calibrated double-spin centrifugation protocol that yields a platelet concentration of ~5× baseline. The protocol below is what the published literature most consistently supports.
Induction phase
Three sessions, one month apart. This is where the underlying follicle activation happens. Skipping induction sessions significantly reduces response rates.
Maintenance phase
One session every 3–4 months for 12–18 months. Holds gains and continues to build density.
Long-term schedule
One session every 6 months. Used by patients who have achieved their goal density and want to preserve it.
Combination protocols
PRP is commonly combined with oral finasteride / minoxidil, topical minoxidil, laser cap therapy, or scheduled around a hair transplant for enhanced graft survival.
What a PRP session actually looks like
| Stage | What happens | Duration |
|---|---|---|
| Check-in | Consent review, photos taken, blood pressure recorded | 10 minutes |
| Blood draw | 15–20 ml standard venous draw (like a GP blood test) | 5 minutes |
| Centrifugation | Double-spin separation — you wait in the treatment room | 12 minutes |
| Scalp prep | Cleansing, optional topical anaesthetic | 10 minutes |
| Injection | ~30 micro-injections delivered across thinning zones | 15 minutes |
| Aftercare | Post-treatment instructions, next session booked | 5 minutes |
How much does PRP cost in the UK?
| Package | What’s included | Typical UK price |
|---|---|---|
| Single session | One PRP treatment | £295 – £395 |
| Induction package (3 sessions) | Three monthly sessions with photographic review | £795 – £1,095 |
| 12-month programme | Induction + 3 maintenance sessions | £1,395 – £1,895 |
| Post-transplant PRP enhancement | Two sessions at month 3 and month 6 post-op | £495 – £695 |
What does the clinical evidence say?
PRP for androgenetic alopecia is supported by a growing body of randomised controlled trials. A 2023 systematic review in the Journal of the American Academy of Dermatology analysed 30 RCTs (n = 1,344) and found that PRP produced a statistically significant increase in hair count and hair diameter versus placebo at 3 and 6 months.
Response is not universal. Around 15–20% of patients in published studies are non-responders, which is why Vinci includes a formal 3-month review checkpoint with photographic comparison. If a patient is not responding, we adjust the protocol — or recommend a different treatment entirely.
Combining PRP with a hair transplant
Around 60% of Vinci’s transplant patients opt to add PRP to their surgical plan. The most common scheduling is:
- Intra-operative PRP: PRP is applied to the grafts in the holding solution and injected into the recipient area at the end of surgery. Supports graft survival in the critical first 72 hours.
- Month 3 post-op: First follow-up PRP. Coincides with the emergence of new growth. Reduces shock loss in surrounding native hair.
- Month 6 post-op: Second follow-up PRP. Supports density building as grafts mature.
PRP vs mesotherapy
| Criterion | PRP | Mesotherapy |
|---|---|---|
| Source material | Your own concentrated platelets | Cocktail of vitamins, amino acids, peptides, minerals |
| Session time | 45–60 minutes (includes blood draw) | 30 minutes |
| Evidence base | Stronger for androgenetic alopecia | Stronger for nutritional / stress-related shedding |
| Typical price | £295 – £395 per session | £125 – £195 per session |
| Combination potential | Often combined with mesotherapy on alternating months | Often combined with PRP on alternating months |
Frequently asked questions
Does PRP actually grow new hair?
PRP does not create new hair follicles. It reactivates dormant follicles and thickens miniaturising ones. In practical terms, this usually appears as improved density and shaft thickness in the first 3–6 months.
Is PRP painful?
The scalp is quite sensitive, but a topical anaesthetic is offered as standard at Vinci. Most patients rate discomfort as 3–4 out of 10 during the injection phase, resolving immediately after.
How many sessions do I need?
Three induction sessions (monthly) is the minimum. Patients who stop after one or two sessions usually report disappointing results. After induction, maintenance sessions are every 3–4 months.
When will I see results?
Objective improvement is typically measurable at 12 weeks on clinical photography. Subjective improvement (hair feels thicker, less shedding in the shower) often arrives earlier — sometimes from session 2.
Are there side effects?
PRP uses your own blood, so allergic reactions are extremely rare. Expected effects include mild scalp tenderness and pinpoint redness for 24–48 hours. Very rare: small bruises at injection sites.
Can I combine PRP with finasteride or minoxidil?
Yes — in fact, combination therapy outperforms either treatment alone in most studies. Vinci commonly prescribes finasteride and topical minoxidil alongside a PRP programme.
Is PRP available at every Vinci clinic?
Yes. All eight UK and Ireland clinics are equipped for in-house PRP. The protocol is identical regardless of location.
