Briefly, mesotherapy can be defined as complementary and alternative treatment which is applied to the middle layer of the skin as a drug injection. Minerals, vitamins, antioxidants and some nutrients such as protein which are needed by the hair cells, are injected via sterilized slim needle and disposable injectors, in the middle layer of the skin where the hair follicles are located, and this process is called hair mesotherapy. With this method, the nutrients are injected directly to the hair roots. This easy applicable method prevents hair loss by providing nutrition of the hair cells.
