Mesotherapy (from Greek mesos, "middle", and therapy from Greek therapeia, "to treat medically") is a non-surgical cosmetic medicine treatment. Mesotherapy employs multiple injections of pharmaceutical and homeopathic medications, plant extracts, vitamins, and other ingredients into subcutaneous fat. Depending on the indications, it can be used for hair loss prevention and hair re-growth. It is highly recommended to opt for mesoscalp in combination with Derma roller or an Insulin syringe.
