DHI (direct hair implantation) method is a very preferred transplantation method that is beneficial in protecting the existing hair, as the grooving and transplantation process is performed at the same time, using thin-tip special medical pens named choi, and the hair follicles are planted without any damage, and it allows the planting between the hairs. Since there is no need to inject liquid under the skin during planting, the possibility of edema after the operation is minimized. The recovery process is very fast since there is no cut in the DHI method. Since the transplantation and grooving process takes place at the same time, the grafts do not wait for a long time in the external environment and the transfer of the hair follicles is faster and healthier.
