Background and objective: As a minimally invasive procedure, mesotherapy has been used in the cosmetic field for half a century and gets favorable results in fat reduction, facial rejuvenation, and hair regrowth. So far, it has achieved some exciting progression in pattern hair loss (PHL), which bothers plenty of people and has cost billion dollars searching for more effective treatment. The aim of this study is to summarize the efficacy of mesotherapy treating PHL.
Methods: Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and Web of Science were searched until January 2021. All literature was evaluated according to established criteria.
Results: We got 336 studies from searched databases, and 12 studies were included after selection process. A total of 253 males and 274 females participated in 6 randomized control trials, 2 nonrandomized controlled trials, and 3 observational studies. Mesotherapy showed positive efficacy in all studies to a certain extent, and no significant side effect occurred.
Conclusion: Mesotherapy demonstrated as an effective treatment for PHL. However, the sample size is not big enough, and studies about mesotherapy compared to other treatments are insufficient. Future research is required to claim more evidence.
