DHI Hair Implantation (Direct Hair Implantation) means ‘Direct Hair Implantation’. In this method, grafts are collected with the help of a medical pen called choi, which should only be used by specialists, and then the hair taken with this pen is directly implanted into the skin without incisions and channels. In known hair transplantation methods, these two procedures are performed at separate times, but thanks to the special pen used, the procedure is reduced to one, providing comfort and convenience to the patient. In short, while the process is three-stage in the hair transplantation technique called FUE, it is two-stage in DHI. The aim of the application is to increase the quality of hair transplantation, to provide a dense appearance, to preserve the existing hairy appearance and to ensure that the person who has hair transplantation can quickly return to his daily life without shortening the hair. Thanks to this method, which has many advantages in many aspects, it is possible to have natural-looking, strong and healthy hair; It is possible to completely control the hair loss problem that occurs due to factors such as genetics or stress.
