hair restoration treatment performed with a Choi implanter pen to treat hair loss in men and women painlessly and in a short time. DHI technique is developed upon the basis of graft extraction – transplantation technique (such as in Follicular Unit Extraction) in which hair follicles are harvested from a donor area (a place in the body where hair is extracted, usually the back of the head) and implanted to the recipient area where balding is experienced.DHI technique is regarded as a breakthrough in hair transplant procedures to achieve the most natural-looking results. The use of the Choi pen makes it possible to implant hair more densely, with very little impact on the integrity of the skin and perform hair transplant without shaving the head completely
