DHI (Direct Hair Implantation) means “Direct Hair Transplantation”. In this method, a medical pen called an implanter is used by experts in the field. After the grafts (Hair Roots) are placed into the implanter pen, which has a sharp, very thin and cylindrical tip, they are planted in the area where the shedding occurs in one step, thanks to the pushing feature of the pen. In this method, there is no need to open channels on the scalp and thus comfort is provided to the patient. In the FUE DHI technique, the grafts are collected using the FUE method, as in other techniques.
