The second part of this Hair Transplantation review concentrates on technical aspects of the surgery. First, we review the two main local anesthetics used in hair transplantation, lidocaine and bupivacaine, how to achieve long-lasting local anesthesia, and the techniques used to minimize the pain associated with anesthetic infiltrations. Second, we review the two donor harvesting techniques currently used: strip harvesting FUT and FUE. The technical aspects of each technique are described in detail, along with their advantages and drawbacks. Third, the different methods of graft implantation currently used by the majority of hair surgeons, including premade sites and stick-and-place, and the use of tools such as implanters are discussed. Finally, post-operative care, expected results, and the main complications involved in hair transplant surgery are reviewed.
