Direct Hair Implantation (DHI) is an advanced type of FUE (Follicular Unit Extraction) technology. In traditional FUE, the surgeon first manually prepares channels in the scalp, after which hair follicles are transplanted. DHI, however, employs a specialized tool called the Choi Implanter Pen, allowing for the simultaneous creation of channels and the implantation of hair follicles. This pen-like tool has a hollow needle measuring 0.5-1.5 mm in diameter.
DHI is a modification of the FUE technique of hair transplantation and follows the same process. Hair follicles are extracted from a donor area, typically the back of the head, and then transplanted to the balding area. These transplanted follicles will eventually grow new hair. The typical steps of the procedure include: The shaving of the patient's head and administering a local anesthetic. With a fine-tipped instrument, the hair follicles are removed from the donor area. The hair follicles are loaded into the Choi Implanter Pen and transplanted to the recipient area. The application of antibiotic cream and bandages to the treated area. The procedure takes approximately 8 hours, depending on the number of follicles being transplanted. Full results can take between 12 to 18 months to appear.
The technique is at the forefront of science in hair transplant and restoration.
The technique is minimally invasive.
The micro-instruments used have a diameter of 1 mm or less.
The procedure is painless, with a shorter recovery time.
The technique allows for full control in terms of the depth, direction, and angle of placement to achieve the most natural results.
DHI Hair Transplantation is best suited for patients with minimal loss of hair. It is difficult to perform the procedure for more than 4000 grafts using the DHI method.
