We call the hair border where the forehead is combined with the hair area “hair line”. Obtaining a naturally appearing hair line: requires the operator to have hand skill as well as a kind of artistic skill. The hair line should be compatible with related limits in the face and therefore should be evaluated in certain mathematical rules aesthetically. In İstanbul Hair Club, the hair line is determined with a special laser device providing full symmetry. The naturality of the hair line is completely related to the natural appearance of the procedure performed. Therefore, İSTANBUL HAIR CLUB works with a special geometric transplantation method developed by its own and only with anatomic single follicular units.
