The process of hair transplantation is carried out using hairs taken from the nape of the head, referred as a donor area. Hair follicles present in this area are less susceptible to testosterone or other causes of hair loss and do not fall out throughout life during transplantation in the desired area.
The important point here is that these hair roots, extracted from the donor area, are gathered without damaging them, after they remain until transplanted to the desired area, and the grafts are inserted without harming.
The good result of hair transplantation determines the number of transplanted healthy and live grafts. However, under surveillance of these conditions, hair transplantation is permanent and guaranteed.
