Mesotherapy is a surgical technique that involves injecting very small, microinjections of medicated substances directly under the skin. In the process, a number of medicines / vitamins / solutions/stem cells are injected into the scalp tissue near the hair follicles (mesoderm) to stimulate hair growth. These are to act as hair growth factors. Multiple such injections are given into the problem areas directly at the site of the problem. The injecting needles used are very thin to minimize the pain.

A lot of motorized machines like meso pens, meso guns, meso rollers are used for injection ease and patient comfort. Topical anesthesia is used to numb the area to be treated.
