Hair Mesotherapy: Vitamin and Drug Injections
Why mesotherapy is a delivery method rather than one treatment, with evidence and injection risks.
Not a single treatment
Mesotherapy is an injection route. Vitamin mixtures, peptides, dutasteride and other drugs do not have interchangeable efficacy.
Evidence
Strong evidence for vitamin or biotin injections in androgenetic alopecia without deficiency is lacking. Intradermal dutasteride studies are limited and heterogeneous.
Safety
Infection, allergy, nodules, scarring and systemic effects of injected drugs can occur. Sterility and product authorisation must be assessed.
Clinical selection
Diagnosis, ingredients, intended outcome, follow-up and consent should guide selection instead of a fixed session package for everyone.
Limits of the evidence
These are selected clinical sources and expert recommendations, not a new systematic review. Formulations, participants, controls, follow-up and adverse-event reporting differ. Positive findings do not establish identical benefit or local authorisation for every patient or product.
Topic-specific questions
Does the word mesotherapy identify one active ingredient?
No. The actual substance, concentration and evidence must be specified.
Does injection prove a vitamin works when no deficiency exists?
No. The delivery route does not establish a clinical benefit.
