Does mesotherapy actually help with pattern hair loss, and does it work for women as well as men? A 2022 systematic review pulled together every eligible study on the question. Across 12 studies covering 253 men and 274 women, every single one reported some degree of positive effect, and none reported a significant side effect. That is an encouraging picture, but the reviewers were careful with their wording, and this article is careful with it too: the evidence is consistently positive, and consistently modest in scale.

Quick answer
-
All 12 included studies reported positive results for mesotherapy in pattern hair loss, though the reviewers hedged with the phrase "to a certain extent", and so should you.
-
It covered both sexes almost equally: 253 men and 274 women, which is unusual in hair loss research, where women are often an afterthought.
-
The safety record was clean: no significant side effects occurred in any of the 12 studies.
-
The main caveat is size: the individual studies were small, and the reviewers concluded that larger trials and head-to-head comparisons with standard treatments are still needed.

Why does this review matter?
Individual hair loss studies are easy to cherry-pick: a single positive trial may hide a design flaw or a tiny sample. A systematic review is the antidote. The authors define search criteria in advance, sweep the major medical databases, and include every study that meets the bar, whether its result is flattering or not.
That is what Tang and colleagues did for mesotherapy, the technique of delivering active ingredients into the mesoderm layer of the scalp through shallow microinjections. Mesotherapy has been used in cosmetic medicine for roughly half a century, but its evidence base for pattern hair loss had never been formally summarised. This review was one of the first to do it, and a 2023 review by Gupta and colleagues later extended the picture with a closer look at the individual ingredients used.
What did the review cover?
The team searched four major databases (the Cochrane Central Register of Controlled Trials, PubMed, EMBASE and Web of Science) up to January 2021. The search returned 336 studies; after screening, 12 made the cut.
Those 12 studies enrolled 527 people in total: 253 men and 274 women with pattern hair loss. Six of the studies were randomised controlled trials, the strongest design available, and the remainder were non-randomised controlled trials and observational studies. The near-even split between men and women matters: female pattern hair loss is common but chronically under-studied, and a body of evidence in which women are actually the slight majority is genuinely rare.
What did the review find?
| Measure |
Result |
| Studies included |
12 (six randomised controlled trials) |
| Participants |
527 in total: 253 men, 274 women |
| Efficacy |
Positive in all 12 studies, to varying degrees |
| Significant side effects |
None reported in any study |
The headline sentence from the results is worth quoting exactly: "Mesotherapy showed positive efficacy in all studies to a certain extent, and no significant side effect occurred." Both halves matter. A 12 for 12 positive record is unusual in hair loss research, where null results are common, and a clean safety record across 527 participants is a meaningful data point for a technique that involves repeatedly puncturing the scalp.
The authors' overall conclusion was that mesotherapy "demonstrated as an effective treatment" for pattern hair loss. Larger real-world data points the same way: a clinic series of 541 patients treated with mesotherapy, published the same year, reported encouraging outcomes outside the controlled trial setting.
What does "to a certain extent" actually mean?
This is where an honest summary has to slow down. The reviewers did not write that mesotherapy showed strong efficacy; they wrote that it showed positive efficacy "to a certain extent". That hedge is doing real work: the size of the benefit varied from study to study, and some of the reported gains were real but modest.
The authors were equally direct about the two structural weaknesses in the evidence. First, sample size: 527 people across 12 studies means the average study enrolled around 44 participants, and small studies are more prone to flattering results. Second, comparisons: they judged that studies pitting mesotherapy against established treatments were insufficient, so the review cannot tell you whether mesotherapy beats, matches or trails the standard options. Their closing line was a call for more research, not a victory lap. Twelve positive studies with those caveats attached amount to promising evidence rather than proof.
What does this mean for your routine?
Three practical points follow. First, mesotherapy has a consistent, all-positive evidence base for pattern hair loss in both men and women, which earns it a legitimate place in a hair care routine. Second, its clean safety record across all 12 studies makes it a reasonable option to try before more invasive or systemic treatments. Third, keep your expectations calibrated: the evidence supports a real but variable benefit, not a guaranteed transformation.
Clinical mesotherapy means injections at a clinic, but the same delivery principle, getting active ingredients through the skin barrier to the follicle, is what our At-Home Hair Mesotherapy Kit is built around for home use. Whichever route you take, our hair mesotherapy guide walks through how the technique works and how to think about frequency.

Frequently asked questions
Does mesotherapy work for female pattern hair loss?
The evidence in this review suggests yes. Women were actually the slight majority of participants, 274 of the 527 people studied, and every included study reported some degree of positive effect.
Is mesotherapy safe for the scalp?
In this review, no significant side effects occurred in any of the 12 included studies, across 527 men and women. It is still a procedure that punctures the skin, so hygiene and technique matter, but the published record here is clean.
How strong is the evidence overall?
Consistent but limited. All 12 studies were positive, and 6 were randomised controlled trials, yet the reviewers stressed that the individual studies were small and that mesotherapy has rarely been tested head to head against standard treatments. Treat it as promising evidence, not settled science.
Is mesotherapy better than minoxidil or finasteride?
This review cannot answer that. The authors explicitly noted that studies comparing mesotherapy with other treatments are insufficient, and they called for future research to fill that gap. What the review does show is that mesotherapy has its own positive evidence base, not that it outperforms the established options.
How many studies and people did the review include?
The authors screened 336 studies and included 12, six of them randomised controlled trials, with 527 total participants: 253 men and 274 women.
