In follicular-unit transplantation (also known as the “strip method”), a long, thin piece of tissue is removed from the back of the scalp. Individual follicular units are then removed from the strip using stereo-microscopic dissection. The follicular units, or grafts, are then placed with surgical precision into the sites prepared for them. The number of grafts transplanted varies from person to person and mainly depends on how much hair you have lost. Typically, around 2,000 grafts, each containing one to three hairs, are transplanted. It is possible to transplant up to 3,500 grafts in a single procedure day.
