It is a method that has become widespread in recent years and makes hair transplantation easier.
It is technically similar to the FUE hair transplantation method, it can be applied without cutting all of the hair by shaving a certain section from the hairy area. The DHI hair transplantation (Unshaved Hair Transplantation) method, also known as direct hair transplantation and pen technique, is the process of transplanting individual hairs to the scalp with a pen-like implanter device (Choi implanter). As in the FUE method, without opening a channel, the grafts are placed in the area to be transplanted directly with the pen (Choi implanter) and thus there is no risk of infection when transplanting between long hair.
