Do PRP Hair Clinics Guarantee Regrowth? What an Honest Clinic Can and Cannot Promise
If you are weighing up PRP for thinning hair, you are probably asking one question before any other: will it work for me? Here is the straight answer. No reputable clinic can guarantee PRP regrowth, and a clinic that does is promising something the science cannot deliver. The good news is that PRP has real trial evidence behind it for the right person, and a well-run clinic can give you something better than a guarantee: a doctor-led assessment, a plan with measurable review points, and an honest answer on whether you are likely to benefit.

What the evidence says PRP can do
PRP (platelet-rich plasma) is made from a small sample of your own blood. It is concentrated and injected into the scalp to support miniaturised follicles. Systematic reviews and meta-analyses of randomised controlled trials in androgenetic alopecia, the common pattern of hair loss in men and women, report improvements in hair density and hair thickness compared with control treatments. The effect is moderate rather than dramatic, and it varies between people. That variation is exactly why a flat guarantee cannot be honest.
Three things shape your result: the type of hair loss (pattern loss responds best; scarring alopecias and some medical causes do not), how far it has progressed (follicles that are shrunken but alive can respond; follicles long gone cannot), and how closely the plan is followed (a course, then maintenance). A good clinic will tell you which group you are in before you pay.
Five signs of an honest PRP clinic
1. A doctor assesses you first. Your pattern of loss, history, medicines and, where needed, blood tests (thyroid, iron and vitamin D are common culprits) should be reviewed before any treatment is suggested.
2. They tell you who PRP will not help. If a clinic never says no, treat that as a red flag.
3. You get a defined course and review points. Typically an initial course of three sessions, then maintenance. Ask when you will be reviewed and what “working” looks like.
4. Baseline photographs are taken. Hair changes slowly, and memory is unreliable. Standardised photographs in the same light and angles let you and your doctor judge progress fairly.
5. The price is clear before you commit. At The London PRP Clinic a single session is £450 and a course of three is £1,215. No hidden extras, and no pressure to prepay for more than the plan you have agreed.

What a realistic timeline looks like
Hair grows slowly, so judge PRP over months rather than weeks. Many people notice reduced shedding first. Thicker, denser growth then builds across the course and the months that follow. Gains are usually held with maintenance sessions every three to six months, because the effect fades without them. If a clinic promises visible results in a fortnight, be cautious.
Free checklist: questions to ask any PRP clinic
Who will inject me, and what are their qualifications? Will a doctor see me before I pay? How is the blood processed, and is the kit single-use? What results are realistic for my type of hair loss? What happens at review if I am not responding? What does the whole course cost, in writing? What numbing and aftercare are included? A clinic confident in its care will answer all of these plainly.
How PRP fits with other treatments
PRP is often combined with minoxidil or finasteride, and it pairs well with hair transplant surgery before and after. Your doctor can explain the benefits and side effects of each so you choose with full information. If another cause is behind your hair loss, treating that first is usually the quickest route to improvement.

Frequently asked questions
Do PRP hair clinics guarantee regrowth?
Reputable clinics do not. Results vary with your type and stage of hair loss. What a good clinic offers instead is a doctor-led assessment, a defined plan, baseline photographs and review points so progress is measured rather than promised.
How do I know if PRP will work for me?
A doctor can judge from your pattern of loss, history and sometimes blood tests. PRP tends to suit early to moderate pattern loss where follicles are miniaturised but still alive.
How many sessions are needed?
An initial course is commonly three sessions, followed by maintenance every three to six months. Your doctor will tailor this to you.
How much does PRP for hair cost at The London PRP Clinic?
£450 per session or £1,215 for a course of three. Consultations are £59 by phone, £150 by video or £220 in person.
What if PRP does not work for me?
It is better to find out early. Baseline photographs and review points show whether you are responding, and your doctor can adjust the plan or discuss alternatives.
Is PRP safe?
PRP uses your own blood, so allergic reactions are rare. Expect scalp tenderness and mild swelling for a day or two. Sterile single-use kit and a medical injector matter.
