DHI (Direct Hair Implantation) hair transplant is defined as the process where hair is taken from the donor area without shaving and directly implanted into the recipient area using special needles. Since the hair follicles are implanted shortly after being taken from the donor area, the risk of damage is minimal. The DHI method, which facilitates implantation between existing hair, is also preferred in small areas.
Unlike the classic FUE method, after each hair follicle is taken, it is transferred to the recipient area without being stored, with an equal angle and direction. This method, also known as the “pen technique,” is performed using special pens called “choi” or “implanter.”
