Hair loss affects a signicant portion of population with a prevalence cited as high as 85% among males and 40% among females [29]. It results in reduced self-esteem and is often a source of psychological distress in affected men and women. Medical treatment including nasteride and minoxidil are shown to only delay progression of hair loss and promote some partial growth. The recent advancements in surgical hair transplantation have made this procedure a safe and effective method to restore a more natural and youthful hair pattern in patients that meet candidacy. There are two hair transplantation techniques, the follicular unit transplantation (FUT) and follicular unit extraction (FUE) techniques. These techniques have largely sup­planted the historical surgical options in hair loss treatment of plug grafts, scalp reductions, and transposition aps. The FUE technique is the more commonly applied approach due to its cited advantages that include increased number of har­vestable grafts, ability to target follicles of a specic size, diameter or pigmentation, increased freedom to adopt any hairstyle due to minimal scarring, reduced postop­erative pain, and faster postoperative healing. The use of additional modalities such as platelet-rich plasma injections, lasers, and stem cells are considered to further enhance the survival and appearance of hair transplants. Another recent innovation in the eld of hair restoration is introduction of robotic technology to maximize patient outcomes. There is a FDA-approved robotic device developed specically for the FUE procedure in male patients. The robot scans and digitizes the visual characteristics of the donor area and analyzes each follicular unit including the fol­licular unit density and hair angulation. The robotic arm has a dual-chamber needle for harvest of the selected follicular units that includes a sharp tip to enter the skin and a surrounding coring blunt punch that then goes deeper into the tissue to limit the chance of transection [30]. Studies comparing the robotic versus manual tech­niques are lacking; however, the proposed advantages of the robotic system include a more accurate and faster graft harvest, decreased follicular transection rate, and increased implantation accuracy at the recipient site [29]. More recently, advance­ments in the FUE techniques have allowed expansion of hair transplantation to the non-scalp hair-bearing regions of the face including beard, eyebrows, and sideburns.
