A doctor-led guide to PRP for hair loss at L'eto Clinic (Leto Clinic) Fulham (SW6, Parsons Green) and Ealing (W5). Rebuild density naturally.
Hair loss can be one of the most emotionally difficult things to notice happening. Whether it's a receding hairline, a widening parting, thinning at the crown, or more hair than usual in the shower drain, the impact on confidence rarely matches the size of the physical change. The good news: there are now several genuinely effective non-surgical treatments — and PRP is one of the most consistent. At L'eto Clinic, PRP hair loss treatment is one of our most requested treatments, chosen by patients across Fulham, Chelsea, Parsons Green, Sands End, Hurlingham, Ealing, Park Royal, Acton and Chiswick.
Here's an honest guide to what PRP actually does for hair loss, who it works for, and what results to realistically expect. You can also explore our full range of injectable treatments.
PRP stands for Platelet-Rich Plasma. It is a treatment that uses your own blood — specifically, a concentrated dose of platelets and their growth factors — to stimulate healing and regeneration. In the context of hair loss, PRP is injected directly into the scalp to reactivate weakened hair follicles and encourage new growth.
Because PRP is derived from your own body, it is autologous — there is no foreign product, no synthetic ingredient, and virtually no risk of allergic reaction. This is one of the reasons PRP has become such a well-established treatment in modern trichology.
Hair follicles do not simply die overnight. In androgenetic (pattern) hair loss, they gradually miniaturise — producing progressively finer, shorter, weaker hairs before eventually stopping altogether. PRP works by delivering a high concentration of growth factors directly to these struggling follicles, which:
PRP does not create new follicles. What it does is give the follicles you still have the best possible environment to produce healthy hair.
PRP is most effective for people in the earlier and mid stages of hair loss, where miniaturised follicles are still present. It is a strong option for:
Honest expectations are half the treatment. PRP is not appropriate — or realistic — for:
If PRP is unlikely to help you, we will say so at your consultation and either recommend an alternative or a combination approach.
Your PRP appointment usually takes 45 to 60 minutes. It follows a straightforward three-step process.
A small amount of blood — usually 20 to 40 ml — is drawn from your arm, just like a routine blood test. There is no fasting requirement and no preparation beyond good hydration.
Your blood is placed in a medical-grade centrifuge that separates it into layers. The platelet-rich plasma layer, containing 3 to 7 times the normal concentration of platelets and growth factors, is carefully collected.
The PRP is injected across the areas of thinning using very fine needles, at a depth that targets the follicle base. Numbing cream is applied beforehand and cold air or vibration devices are used to minimise discomfort. Most patients describe the injections as tolerable rather than painful.
PRP works gradually. Realistic expectations look like this:
Results are not permanent. Hair loss is an ongoing biological process, so we typically recommend a maintenance session every 6 to 12 months once the initial course is complete.
For most patients we recommend an initial course of 3 to 4 sessions, spaced 4 to 6 weeks apart. This gives the growth factors time to compound across the hair cycle. After that, maintenance sessions every 6 to 12 months keep results consistent.
The exact number depends on your stage of hair loss, response to the first sessions, hormonal factors, and whether we combine PRP with other treatments like microneedling or medication.
PRP works well on its own but can be significantly more effective when combined with:
Microneedling before or during PRP creates micro-channels that improve absorption and independently stimulate follicles through controlled micro-injury. See our microneedling guide for more detail.
Medications remain the strongest evidence-based treatments for male pattern hair loss. PRP works well alongside them — it is not a replacement, but a complement that can improve density beyond what medication alone achieves.
Exosome-based scalp treatments are the newer generation of regenerative therapy and can be used alongside or instead of PRP for some patients.
Hair loss often has underlying drivers — iron deficiency, low ferritin, thyroid issues, low vitamin D, and hormonal imbalance are common contributors. We will always recommend appropriate blood work at your consultation to identify factors that need addressing alongside the treatment itself.
For patients who have had or are considering a hair transplant, PRP significantly improves graft survival and post-transplant density. It is now considered standard practice around transplant surgery.
For the first 24 to 48 hours after PRP:
Mild scalp tenderness, redness or tightness is normal for 24 hours. Bruising at injection sites can occur occasionally and resolves within a few days.
PRP has an excellent safety profile because the treatment uses your own biological material. There is no risk of allergic reaction to the plasma itself. When performed in a doctor-led clinical setting with medical-grade centrifuge equipment and sterile technique, complications are rare.
The main safety risks are related to injection technique and hygiene, which is why we advise strongly against PRP at non-medical premises, salons, or by untrained operators.
PRP is not appropriate if you:
A full consultation, including any recommended blood work, determines whether PRP is the right treatment for you.
PRP is one of the few hair loss treatments that is equally effective in men and women — because it addresses the biology of follicle miniaturisation rather than targeting hormones specifically. Around half of our PRP patients are women dealing with post-partum, perimenopausal, or telogen effluvium hair thinning, and half are men addressing male pattern hair loss. Both groups see significant improvement when treatment is started early enough.
Leto Clinic Fulham is at 291 New King's Road, Fulham, SW6 4RE, at the Parsons Green end of the King's Road — a short walk from Parsons Green and Fulham Broadway tube stations, and minutes from Chelsea along the King's Road. Patients travel to us for PRP hair loss treatment from Chelsea, Fulham, Parsons Green, Sands End, Hurlingham, South Kensington, Earl's Court, Putney, Wandsworth and Hammersmith.
Leto Clinic Ealing is a convenient choice for patients across West London — Ealing, Park Royal, Acton, West Ealing, Hanwell, Northfields, Brentford and Chiswick — a great option if you want to build a regular treatment course close to home.
Every PRP treatment at L'eto Clinic is delivered in a doctor-led environment using medical-grade centrifuges and sterile technique. Just as importantly, we take a whole-picture approach: we won't start you on a PRP course without discussing the underlying drivers of your hair loss, blood work where indicated, and other treatment options that may work alongside or instead of PRP. Read more about our clinic, or explore our wider range of injectable treatments.
Cost depends on the number of sessions in your course and whether we combine PRP with microneedling or other treatments. We provide a clear fixed quote at your consultation, and a course is significantly better value than paying per session.
The blood draw is a routine needle stick. The scalp injections feel like short pricks with mild pressure. Numbing cream and cooling devices make the experience comfortable for the vast majority of patients. Most describe it as tolerable rather than painful.
A hair transplant physically relocates your existing hair follicles to areas of loss. PRP does not add new follicles — it improves the health and output of the follicles you still have. Many patients combine both: PRP to keep the surrounding hair as healthy as possible, and a transplant to fill in areas already lost.
PRP uses your own blood-derived platelets. Exosomes are laboratory-produced regenerative signalling molecules (typically from stem cells) that can deliver more concentrated growth signalling but are more expensive. Both are effective; the right choice depends on your hair loss stage, budget and clinical picture.
Hair loss is an ongoing condition, so maintaining results does require occasional maintenance sessions — typically once every 6 to 12 months. Stopping treatment entirely will eventually see hair loss resume its natural course.
Yes — combining PRP with medication is often the most effective approach. We'll ask about your current regimen at your consultation and design a plan that complements it.
Reduced shedding is often the first noticeable change, within 2 to 4 weeks. New hair growth becomes visible from 2 to 3 months, with peak density at 6 to 12 months.
Yes, PRP can be used to stimulate hair growth in eyebrows and patchy beards, though the treatment protocol is more targeted. This is discussed on a case-by-case basis.
