The most obvious difference between the dhi method (direct implantation of the FUE hair transplant hair cover and the fue method is that the hair roots are embedded in the skin by means of a pencil with a specialized edge without opening the channel. It is also common as a dhi pen method. Since there is no need to open a site in the donor area, an intensive appearance of the hair is also achieved due to an increase in the number of roots and the likelihood of implantation of more hair. At the same time, because the roots are placed directly into the area without opening the channels or incision, the survival rate of transplants is higher and there are more opportunities to stay healthy. The implantation procedure is longer and more modern than the fue method. However, the procedure for healing the skin of the hair, which is not damaged during transplantation by dhi, is shorter.
