What is CHOI (DHI) Hair Transplantation?

CHOI (DHI) hair transplantation technique is one of the most commonly used methods. CHOI DHI (Direct Hair Implantation) is also known as pen technique. During the procedure, follicles are taken from the donor area using Choi pen and are implanted in the transplanted area.

The difference of DHI hair transplantation technique from the others is that channel opening and hair transplantation are performed at the same time. The collected hair follicles are placed in the CHOI pen. Thanks to the CHOI pen, both the channels are opened and the hair follicles are placed in the area to be transplanted at the same time.
