DHI Hair Transplant Technique Operation Process

The similarities of DHI and FUE techniques are striking, but the most important difference that separates the two techniques from each other is that hair transplantation is performed in the area where the hair follicles will be transplanted with the implanter pen without opening the channel in the DHI Technique.
