Direct Hair Transplantation (DHI) is a painless hair transplant procedure that uses the most modern technology for treatments. There is no need to open any holes/channels in the area where they are used for the hair follicles taken for transplantation, and the hair follicles are planted directly with special pens. Since there is no need to open any channels in the area to be used, more roots can be planted and this allows for a more dense planting. The healing process using this technique is much shorter than other methods. The most important advantage of the DHI method is that it allows more intensive graft transfer to narrow areas.
