Finasteride Vs Mesotherapy: How They Compare For Hair Loss
Last reviewed on 2 October 2026. We review our treatment guides every six months to keep them accurate.
Key points
One is a tablet, the other an injection. Finasteride is a daily tablet that lowers the hormone (DHT) driving male pattern hair loss. Mesotherapy is an in-clinic injection of a cocktail into the scalp, and there is no single agreed recipe.
Finasteride is a proven, first-line, licensed treatment. It reliably lowers the DHT behind the loss, is cheap, and is especially good at stopping or slowing further thinning.
Mesotherapy is really two different things. A vitamin-and-mineral cocktail only stimulates the follicles and does nothing to DHT; a drug cocktail injects a DHT-blocker such as dutasteride or finasteride directly into the scalp.
Even the drug form is unlicensed and less proven. Injecting finasteride or dutasteride into the scalp uses the same kind of DHT-blocker as the tablet, but by an unlicensed route, and the evidence behind it is far smaller than for the oral tablet.
Finasteride has the far larger and more consistent evidence base, and it is much cheaper than a course of clinic injections.
Neither adds hair or restores a bald scalp. Both work on hair that is still there, so neither can regrow a genuinely bald area, and for that a hair transplant is the only option that adds hair.
Both are ongoing commitments, and oral finasteride is usually the sensible first step. Which suits you is best decided with a clinician.
Finasteride and mesotherapy are both used for male pattern hair loss, but they are very different, and the comparison has a twist. Finasteride is a proven, licensed tablet that lowers DHT. Mesotherapy is a non-standardised scalp injection that, depending on the cocktail, either just stimulates the follicles or injects a DHT-blocking drug directly into the scalp. So part of this comparison is tablet versus injection, and part of it is the proven oral drug versus an unlicensed injected version of the same idea.
This guide compares finasteride and mesotherapy neutrally: what each is, how they differ, how effective they are, what they cost you in commitment 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
Finasteride is an oral tablet that lowers DHT, the hormone that causes male pattern loss, so it treats the underlying cause; it is first-line, licensed, proven and cheap. Mesotherapy is an in-clinic injection with no agreed recipe: a vitamin cocktail that only stimulates the follicles and does nothing to DHT, or a drug cocktail that injects a DHT-blocker such as dutasteride or finasteride into the scalp by an unlicensed route. The drug form is sometimes pitched as lowering DHT with less exposure to the rest of the body than a tablet, but it is unlicensed and far less studied. If you had to choose one, oral finasteride is the proven, licensed and much cheaper option, and the sensible first step; mesotherapy is a clinic alternative mainly for those who cannot or would rather not take oral medication. Neither, though, can regrow a scalp that is already bald.
What is finasteride?
Finasteride is a daily tablet that treats male pattern hair loss by lowering DHT, the hormone that shrinks genetically sensitive follicles. It blocks the enzyme 5-alpha reductase, which, as a review of these drugs in dermatology explains, "converts testosterone to dihydrotestosterone (DHT), which amplifies androgen effects in certain tissues". By blocking it, finasteride produces "a substantial reduction in serum (around 70%)" DHT, and the review notes that "long-term use of finasteride at a 1-mg dose proved to be safe and effective in treating male-pattern" hair loss. It works on the cause of the loss rather than just the symptoms, which is why it is a first-line treatment, and it is licensed for male pattern hair loss. Our guide on finasteride for hair loss covers it in detail, including the possible side effects.
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". The important point for this comparison is that the cocktail varies hugely: some are vitamins and minerals, which only stimulate the follicles, while others contain hair-loss drugs such as dutasteride or finasteride, which inject a DHT-blocker directly into the scalp. There is no single agreed recipe, and the injected drug forms are not licensed medicines. Our guide on mesotherapy for hair loss explains this in detail.
Which is more effective for hair loss?
For tackling the cause of male pattern loss, oral finasteride is much the more proven option. It is a first-line, licensed medicine that reliably lowers the DHT driving the loss, with a large evidence base behind it. Mesotherapy is far less established: the mesotherapy review is candid that its studies "have some limitations, including smaller sample sizes, patients being lost during follow-up, and shorter follow-up periods", and concludes that "more extensive studies need to be established to determine the safety and efficacy of mesotherapy for AGA treatment".
There is an interesting wrinkle, though. A vitamin mesotherapy cocktail only stimulates the follicles and does nothing to DHT, so against the hormonal cause it is weaker than finasteride. A drug mesotherapy, injecting finasteride or dutasteride into the scalp, is aimed at the same target as the tablet, the idea being to lower DHT at the scalp with less of the drug reaching the rest of the body. That is a reasonable theory, and injected dutasteride in particular has some real-world data, but it is an unlicensed route with far less evidence than the oral tablet, and the systemic effects of the injected form are not well established. So the fair summary is that oral finasteride is the proven, licensed way to lower DHT, while mesotherapy, whether a vitamin cocktail or an injected drug, is less proven and not standardised.
Finasteride vs mesotherapy: how do they compare?
The two differ in almost every practical way:
What they are: finasteride is a daily prescription tablet (a drug); mesotherapy is a course of in-clinic injections of a cocktail that varies from clinic to clinic.
How they work: finasteride lowers DHT, the hormonal cause of male pattern loss; mesotherapy either only stimulates the follicles (a vitamin cocktail) or injects a DHT-blocker into the scalp (a drug cocktail).
Evidence and status: finasteride is first-line, licensed and backed by a large evidence base; mesotherapy has smaller, mixed studies and is not standardised, and its injected drug forms are unlicensed.
Cost and routine: finasteride is a cheap daily tablet; mesotherapy is a much more expensive course of clinic injections with maintenance top-ups.
Side effects: finasteride is a systemic hormonal medicine that can cause side effects in a minority; mesotherapy can cause local reactions and, with a drug-containing cocktail, has even been linked rarely to paradoxical hair shedding.
The same drug, a different route: a finasteride or dutasteride mesotherapy injects the same kind of DHT-blocker as the tablet, but by an unlicensed scalp route pitched as reducing whole-body exposure, with much weaker evidence.
What neither does: neither adds new hair or restores a bald area, so both are for keeping and supporting the hair you still have rather than replacing hair that is gone.
Which is right for you?
If your aim is to tackle male pattern loss at its source with the best-evidenced option, oral finasteride is the logical first step: it treats the cause, is proven and licensed, and is cheap. Mesotherapy is a choice mainly for those who cannot or would prefer not to take oral medication, or who want a clinic-based treatment, accepting that the vitamin form does not treat the cause, the drug form is unlicensed and less proven, the recipe is not standardised, and it costs a great deal more. Some people are specifically drawn to injected finasteride or dutasteride in the hope of lowering DHT with fewer systemic effects, but that trade-off is not well established, and it remains an unlicensed route. 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 varies so much between clinics, it matters to ask exactly what is in the cocktail, whether it contains prescription drugs, and what evidence supports that specific mixture. A clinician can help you weigh a proven, cheap tablet against a non-standardised, more expensive injection.
Can they be combined with other treatments?
Yes, though with finasteride and mesotherapy there is an obvious overlap to watch: if a mesotherapy cocktail contains finasteride or dutasteride, it is doing a similar job to the tablet, so combining them would need care and a clinician’s advice. More usually, finasteride is paired with a follicle stimulant such as minoxidil, which we compare in our guide on finasteride versus minoxidil, and mesotherapy sits among the injectable options compared in our guides on minoxidil versus mesotherapy and PRP versus mesotherapy.
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 a proven treatment like finasteride is often used around a transplant to protect and support the result; our guide on finasteride versus PRP looks at how a tablet and a scalp treatment fit together. The key point is that finasteride and mesotherapy are usually part of a wider plan, with the proven treatment the foundation.
The bottom line
Finasteride and mesotherapy are very different, and the comparison has a twist. Finasteride is a cheap, licensed, first-line daily tablet that lowers DHT and treats the cause, with strong evidence behind it. Mesotherapy is a non-standardised clinic injection that, depending on the cocktail, either only stimulates the follicles (a vitamin mix, which does nothing to DHT) or injects a DHT-blocking drug into the scalp by an unlicensed route (a drug mix, pitched as lower whole-body exposure but far less proven). Neither adds hair or restores a bald area.
If you had to choose one, oral finasteride has far the stronger evidence, treats the cause, and costs a fraction of a course of injections, while mesotherapy is a non-standardised clinic alternative mainly for those who cannot or will not take oral medication. A clinician can help you decide which, including exactly what any mesotherapy cocktail would contain, and how it might fit alongside other treatments or a hair transplant.
Frequently asked questions
Is finasteride or mesotherapy better for hair loss?
For tackling the cause of male pattern loss, oral finasteride is much the more proven and far cheaper option, because it is a first-line, licensed medicine that reliably lowers DHT. Mesotherapy is less established: a vitamin cocktail only stimulates the follicles, and even a drug cocktail that injects finasteride or dutasteride is an unlicensed route with far less evidence than the tablet. So finasteride is usually the sensible first choice, with mesotherapy more of a clinic alternative for those who cannot or will not take oral medication.
Is injecting finasteride into the scalp better than taking the tablet?
It is not proven to be. Injecting finasteride or dutasteride into the scalp, a form of mesotherapy, aims to lower DHT at the scalp with less of the drug reaching the rest of the body, which is a reasonable theory and appeals to people worried about systemic side effects. But it is an unlicensed route with far less evidence than the oral tablet, the recipe and dose are not standardised, and whether it really reduces whole-body effects is not well established. The oral tablet remains the proven, licensed option.
What is the difference between finasteride and mesotherapy?
Finasteride is a daily tablet, a drug that lowers DHT, the hormone behind male pattern hair loss, so it treats the underlying cause. Mesotherapy is a course of in-clinic injections of a cocktail that varies between clinics: a vitamin-and-mineral mix that only stimulates the follicles, or a drug mix that injects a DHT-blocker such as dutasteride or finasteride into the scalp. So finasteride is a proven, licensed oral drug, while mesotherapy is a non-standardised injection that may or may not target DHT, and whose injected drug forms are unlicensed.
Do finasteride or mesotherapy regrow hair on a bald scalp?
No. Both work on follicles that are still present: finasteride by cutting the hormone that shrinks them, mesotherapy by stimulating them or, in its drug form, by blocking DHT at the scalp. Neither can grow hair where the follicles have already been lost, so neither will restore a genuinely bald or fully receded area. For that, a hair transplant is the only option that adds hair to bare scalp. Finasteride and mesotherapy are best used earlier, to keep and support the hair you still have, rather than as a cure for baldness.
