hairlossWhat is hair mesotherapy?
Mesotherapy delivers substances into the middle layer of the skin through many shallow injections or a multi-needle device. For hair loss, the mixture may contain drugs used for pattern hair loss, vitamins, amino acids, growth factors or other compounds. There is no single standard recipe, which makes it hard to compare one clinic's treatment with another's, or with the published studies.
It is different from PRP (platelet-rich plasma), which uses a concentrate made from your own blood, and from a hair transplant, which moves your own follicles surgically.
What the research shows
A 2022 systematic review in the Journal of Cosmetic Dermatology found 12 studies of mesotherapy for pattern hair loss, involving 253 men and 274 women. All reported some positive effect and no significant side effects, but the authors flagged small sample sizes and too few head-to-head comparisons with other treatments (Tang et al., 2022).
A 2024 systematic review in Cureus reached a similar view: results are promising, but the evidence is limited by small samples, short follow-up and few studies, and larger trials are needed. It also notes that the US FDA has not approved mesotherapy as a procedure for hair loss (Aledani et al., 2024).
Side effects and safety
Most reported side effects are mild and short-lived: redness, pain at injection sites, itching and headache. The 2024 review also describes rarer, more serious reactions, including forehead swelling, allergic-type skin reactions and paradoxical patches of hair loss (Aledani et al., 2024). One published case describes a delayed allergic reaction to a steroid in a scalp mesotherapy mix that left scarring and permanent hair loss at the injection sites (Lee et al., 2019). Cases like these are uncommon, but they show why it matters who injects you and what is being injected.
Who might consider it
Mesotherapy is usually discussed as an add-on or an option when standard treatments are not suitable or have not worked. Because the evidence is still developing, it is best treated as part of a plan built with a doctor or dermatologist who has first confirmed what is causing your hair loss. Prescription ingredients in particular are a conversation to have with a doctor.
Questions to ask before you book
- What exactly is in the mixture, and why was each ingredient chosen for me?
- Who performs the injections, and what are their qualifications?
- How many sessions are planned, and how will we measure whether it is working?
- What side effects have you seen, and what happens if I react to an ingredient?
- How does this compare with evidence-based options such as approved medications, PRP or surgery for my pattern?

FAQ
Does mesotherapy work for hair loss?
Small studies suggest some benefit for pattern hair loss, but systematic reviews describe the evidence as limited, with small samples and short follow-up. Larger, well-designed trials are still needed.
Is hair mesotherapy FDA-approved?
A 2024 systematic review notes that the US FDA has not approved mesotherapy as a procedure for hair loss, even though some of the drugs used in the injections are approved for other uses.
What are the side effects of hair mesotherapy?
Reported side effects are mostly mild, such as redness, pain, itching and headache. Rarer reactions reported in the literature include swelling of the forehead, allergic reactions and, in some case reports, patches of hair loss at injection sites.
Is mesotherapy the same as PRP?
No. PRP uses a concentrate made from your own blood. Mesotherapy injects a mixture of drugs, vitamins or other substances into the scalp, and the mixture varies widely between clinics.
