DHI (with CHOI Pens)DHI Technique is an avant-garde hair implantation technique that uses a CHOI Pen to implant grafts on the receding and bald areas. While the extraction phase is the same as in the FUE and FUE Sapphire techniques, however, DHI technique is different at the implantation step of the procedure: channel opening and implantation take place simultaneously. Specialists use the CHOI Pen to implant grafts one by one, to achieve the best and most natural hair transplant results. In the DHI method, patients do not have to shave all of their hair, but just the donor area, making it a preferred technique for female hair transplant. The Main Advantages of DHI are: A higher density of hair follicles is achieved on a specific area, such as the hairline, compared to other hair transplant methods. More natural results are achieved, as it is easier to give the right angle and depth to the canals and grafts with the CHOI pen compared to the FUE method. There is no need to shave your whole head. DHI Hair transplant is the best option for patients who do not want to shave their head completely.
