PRP Vs Mesotherapy: How They Compare For Hair Loss
Last reviewed on 26 September 2026. We review our treatment guides every six months to keep them accurate.
Key points
Both are scalp injections. PRP (platelet-rich plasma) and mesotherapy are both given as a course of tiny injections into the scalp to try to stimulate the follicles, and both are minimally invasive in-clinic treatments.
The big difference is what is injected. PRP is made from a small sample of your own blood, spun to concentrate the platelets and their growth factors. Mesotherapy injects a manufactured "cocktail" of vitamins, minerals, amino acids and sometimes medicines, which does not come from your body.
Mesotherapy has no standard recipe. There is no single agreed formula, dose or schedule for mesotherapy, so what is in the injection varies widely from clinic to clinic, which makes it hard to compare or to be sure what is doing the work.
Neither adds hair or reliably treats the cause. Both stimulate follicles that are still there, so they can support thinning areas but cannot regrow a truly bald patch. PRP does not lower the hormone (DHT) behind male pattern loss, and mesotherapy only does so if its cocktail happens to include an anti-androgen drug.
The evidence for both is limited, and thinner for mesotherapy. PRP has more studies behind it, though they are mixed; mesotherapy has fewer and smaller studies, and reviewers repeatedly call for larger, longer trials.
Both need repeated sessions and upkeep, and both are private, cosmetic treatments you would pay for yourself.
Which, if either, suits you is best decided with a clinician, and both are usually combined with proven medication or used around a hair transplant rather than instead of them.
PRP and mesotherapy are both offered as injectable "boosters" for thinning hair, and because both involve a course of scalp injections they are easy to confuse. The key difference is what goes into the needle: PRP uses a concentrate made from your own blood, while mesotherapy injects a manufactured mix of vitamins, minerals and other ingredients. PRP has the larger, if still mixed, evidence base; mesotherapy is less standardised and less well studied.
This guide compares PRP and mesotherapy neutrally: what each is, how they differ, how effective they are, what they cost you in sessions and money, who each suits, and how they fit with other treatments. It is general information and not a substitute for advice from a doctor.
The short answer
PRP and mesotherapy both deliver a course of scalp injections meant to stimulate the follicles you still have, but they differ in what is injected and how well it is backed by evidence. PRP is autologous: it is made from your own blood, so it is a single, consistent preparation, and it has the larger body of research, even if that research is mixed. Mesotherapy injects a manufactured cocktail that varies from clinic to clinic, with no agreed recipe, and its evidence base is smaller and weaker. So PRP is the more standardised and better-studied of the two, while mesotherapy is more variable and less proven, and neither is a cure or a substitute for the treatments that tackle the cause of hair loss.
What is PRP?
PRP, platelet-rich plasma, is made by taking a small sample of your blood and spinning it in a centrifuge to concentrate the platelets, which is then injected into the scalp. As a review of PRP for hair loss describes, its "composition encompasses a rich variety of biological components such as platelets, growth factors, cytokines, and other bioactive proteins", and those growth factors stimulate the dermal papilla cells that drive the hair follicle. The evidence is encouraging but mixed: the review found that "the majority of studies demonstrated that PRP is effective in increasing hair density and thickness in patients with" androgenetic alopecia, while cautioning that "results varied due to differences in preparation protocols, platelet concentration, and delivery methods". Because it is made from your own blood, PRP is autologous and a single, consistent preparation. Our guide on PRP injections for hair loss covers it in detail.
What is mesotherapy?
Mesotherapy is a technique of injecting a mixture of substances into the skin of the scalp. As a systematic review of mesotherapy for hair loss explains, "it involves the microinjection of medications, pharmaceuticals, and vitamins into the mesoderm", and "mesotherapy involves the direct injection of the solution into the scalp, causing multiple trauma induced by the microinjection, which increases the release of cytokines and growth factors into the scalp". So it is thought to work in two ways at once: through the ingredients in the cocktail, and through the mild injury of the injections themselves. The cocktails can be complex; the review notes one "mesohair solution had 56 constituents, which included 24 amino acids, 13 vitamins, four coenzymes, four nucleic acids, five minerals, and two reducing agents", and some formulas also contain hair-loss drugs. The catch is that there is no single agreed recipe. Our guide on mesotherapy for hair loss explains it further.
Which is more effective for hair loss?
Neither has strong, settled evidence, but PRP has more studies behind it. The PRP review found that most studies show PRP improves hair density and thickness in pattern hair loss, while stressing that results vary with how it is prepared and delivered. Mesotherapy has been studied less: the mesotherapy review pulls together a smaller set of trials and repeatedly flags their limits, noting "these studies have some limitations, including smaller sample sizes, patients being lost during follow-up, and shorter follow-up periods", and concluding that "more extensive studies need to be established to determine the safety and efficacy of mesotherapy for AGA treatment".
Where mesotherapy has been compared with the proven topical minoxidil, the results are mixed rather than clearly better: the review cites one study finding "no statistically significant difference between mesotherapy and minoxidil", and another suggesting that in female pattern loss "mesotherapy with vitamins and minerals alone is more successful, patient-acceptable, and bearable than topical minoxidil 5%". So the fair summary is that both PRP and mesotherapy have limited evidence, PRP has rather more of it, and mesotherapy in particular is held back by small studies and the lack of a standard formula.
PRP vs mesotherapy: how do they compare?
Both are courses of scalp injections, but they differ in some important ways:
What is injected: PRP is made from your own blood, so it is a single, consistent concentrate of your own platelets and growth factors; mesotherapy injects a manufactured cocktail of vitamins, minerals, amino acids and sometimes drugs, which does not come from your body.
Standardisation: PRP is one defined preparation (though methods vary between clinics); mesotherapy has no agreed recipe, dose or schedule, so what you receive varies widely.
Evidence: PRP has more studies (mixed but generally positive); mesotherapy has fewer and smaller studies, with reviewers calling for larger, longer trials.
Effect on the cause: neither PRP nor a vitamin mesotherapy cocktail lowers the hormone (DHT) behind male pattern loss; only a mesotherapy mix that contains an anti-androgen drug would act on the cause, and that carries its own risks.
Safety: PRP uses only your own blood, so its safety picture is generally good; mesotherapy can cause more local reactions, and rare problems have been reported, including, with a drug-containing cocktail, paradoxical hair shedding.
Sessions and cost: both are given as an initial course with maintenance top-ups, so both are an ongoing, private cost.
What neither does: neither adds new hair or restores a bald area, so both are for supporting hair that is still there rather than replacing hair that is gone.
Which is right for you?
If you want the better-studied and more consistent of the two, PRP is the stronger choice: it is a single preparation made from your own blood, with the larger evidence base and a good safety record. Mesotherapy may appeal if a clinic offers a specific, well-explained formula and you understand that the evidence is thinner and the recipe is not standardised, but it is worth asking exactly what is in the cocktail and why. Neither, though, suits someone whose loss is advanced or whose follicles are already gone, because both only support hair that is still there.
Because mesotherapy in particular varies so much between clinics, it matters to choose a reputable provider, to ask what is being injected and what evidence supports it, and to be wary of any cocktail containing prescription drugs used off-label. As with any treatment where the evidence is still developing, keep your expectations realistic and discuss with a clinician whether an injectable treatment is the right step for your pattern of loss at all.
Can they be combined with other treatments?
Yes, and in practice both PRP and mesotherapy are usually part of a wider plan rather than a treatment on their own. Because neither reliably addresses the hormonal cause of male pattern loss, they are often used alongside the medical mainstays, which we compare in our guides on finasteride versus minoxidil and minoxidil. They also sit within the wider set of injectable and regenerative options, and our guides on PRP versus PRF and PRP versus exosomes compare the other blood-derived and lab-derived injections.
Neither can restore hair that is already gone. Where loss is more advanced, a hair transplant is a separate option that redistributes your own permanent hair, and an injectable treatment is sometimes used as an add-on around the surgery; our guide on hair transplant versus PRP looks at that. The key point is that PRP and mesotherapy are companions to a treatment plan, not a cure on their own.
The bottom line
PRP and mesotherapy are both courses of scalp injections meant to stimulate the follicles you still have, and neither adds hair or restores a bald area. The difference is what goes in: PRP is a single, consistent concentrate made from your own blood, with the larger (if mixed) evidence base and a good safety record; mesotherapy injects a manufactured cocktail that varies from clinic to clinic, with no agreed recipe, weaker evidence and more possible local side effects. Both need repeated sessions, both are private costs, and both are best seen as part of a wider plan rather than a cure.
If you are weighing them up, a clinician can advise which, if either, suits your hair loss, and how it might fit alongside proven medication or a hair transplant. Whichever you consider, keep expectations realistic, ask exactly what is being injected, and pick a reputable provider.
Frequently asked questions
Is PRP better than mesotherapy for hair loss?
On the current evidence, PRP is the better-studied and more consistent option. It is a single preparation made from your own blood, and most studies show it can improve hair density and thickness in pattern hair loss, though the research is mixed. Mesotherapy has fewer and smaller studies, and reviewers repeatedly call for larger, longer trials, partly because there is no standard cocktail. Neither is a proven cure, but PRP has more behind it and a simpler safety picture.
What is the difference between PRP and mesotherapy?
Both are scalp injections, but they inject different things. PRP is made from a sample of your own blood, spun to concentrate the platelets and their growth factors, so it is entirely your own material and a single consistent preparation. Mesotherapy injects a manufactured cocktail of vitamins, minerals, amino acids and sometimes drugs, which does not come from your body and has no agreed recipe. In short, PRP is autologous and standardised; mesotherapy is a variable, manufactured mix.
Do PRP or mesotherapy regrow hair on a bald scalp?
No. Both work by stimulating follicles that are still present but underperforming, so they can support thinning areas but cannot grow hair where the follicles have already been lost. Neither will restore a bald or fully receded area; for that, a hair transplant is the only option that adds hair to bare scalp. PRP and mesotherapy are best used for early or diffuse thinning, or as a support around other treatments, rather than as a cure for baldness.
Is mesotherapy for hair loss safe?
It is usually well tolerated, but it carries more possible local side effects than PRP, and its safety is less well established. Reported effects include redness, pain, itching, swelling and, rarely, more serious local reactions; there have even been reports of paradoxical hair shedding after a cocktail containing a hair-loss drug. Because there is no standard formula, it is especially important to choose a reputable clinic, ask exactly what is being injected, and be cautious about cocktails containing prescription medicines used off-label.
