Hair mesotherapy is also known as mesoplasty or mesohair. This involves injecting drugs directly into the scalp. This technique acts on the epidermis, connective tissue in the dermis, blood circulation, immune system and nervous system. It can help improve certain forms of alopecia such as telogen effluvium, androgenetic alopecia, alopecia areata and stress alopecia. The purpose of this treatment is to restore and increase microcirculation in the scalp, provide nutrients, slow the shrinking of follicles and stimulate hair growth.
