DHI, or Direct Hair Implantation, is an advanced hair transplant technique that involves the extraction of individual hair follicles from the donor area and their direct implantation into the recipient area using a specialized tool called a Choi Implanter Pen. This method ensures precision and minimizes trauma to the scalp, resulting in faster recovery and natural-looking hair growth. DHI is known for its high graft survival rate and the ability to achieve dense and aesthetically pleasing hair restoration.
