The DHI® (Direct Hair Implantation) is a minimally invasive procedure of hair transplantation with the use of advanced follicular unit extraction procedure. Hair follicles are first selected and extracted one by one from the back of the head. Then, they are implanted directly into the designated region. Healthy growth rate of the hair implanted reaches 95%. In addition, the results are far more natural than that of the traditional skin-cutting method. Less pain and inconspicuous scar will also be resulted.
