The goal in hair restoration is natural-appearing results. Improvements in the field of hair transplantation have developed with this goal in mind. The most recent development is the follicular-unit grafting technique, which relies on microscopic dissection to produce grafts, each containing a follicular unit, the natural bundling of 1 to 4 hairs, with a minimum amount of non–hair-bearing surrounding skin. For patients desiring surgical hair restoration, proponents of follicular-unit grafting advocate the technique for its superior results. Detractors point to the technical challenges of performing the procedure and the need for a staff of trained assistants for the microscopic dissection. What is clear is that this demanding procedure is taking the field of hair restoration the closest ever to its ultimate goal—undetectability.
