Mesotherapy as a Promising Alternative to Minoxidil for Androgenetic Alopecia: A Systematic Review.

Patterned hair loss (PHL) is a severe hair condition that affects both sexes. Mesotherapy is a treatment that involves microinjecting medications and/or vitamins into the middle layer of the skin. Mesotherapy reduces systemic adverse effects by delivering drugs directly to the hair follicle, increasing local bioavailability while lowering systemic exposure. Local side effects and reactions may develop due to mesotherapy. This study systematically evaluated the safety and efficacy of mesotherapy to minoxidil 5%, as well as addressing its limitations, dosing, and technique, with the intent of providing valuable trials and insights for clinicians and patients considering mesotherapy for improved androgenetic alopecia (AGA) outcomes. The literature search carried out by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria yielded 11 relevant studies from an initial pool of 18 articles. These studies covered various aspects of the role of mesotherapy and minoxidil in AGA, including techniques, complications, limitations, and outcomes. In conclusion, available trials and research on mesotherapy and minoxidil demonstrated excellent statistical significance and a high patient satisfaction rate, with the exception of two publications that took into account certain uncommon adverse effects of mesotherapy. However, recent research suggests that a mesotherapy method for alopecia with a low risk of side effects is effective.
