Direct Hair Implantation (Choi Method)
DHI is the newest and most advanced hair transplantation technique. In this technique ; creating the site and implanting the grafts are performed together.

Surgeon uses this implanter pen to collect grafts from the donor area, after they are collected into the hollow needle, the needle inserted into the scalp creating the incision site where the grafts will be implanted.
