A graft simply refers to a follicular unit, which may be a 1-hair, 2-hair, 3-hair, 4-hair, or even a 5-hair follicular unit graft. When hair transplants are performed, the single hair grafts (or follicular units) are inserted into the frontal hairline. Just behind the hairline, the 2-hair follicular unit grafts are placed to add density to the hairline, and behind these are the larger grafts to ultimately add density to the entire scalp and hair restoration procedure. The following diagram shows a close up of 1-hair, 2-hair, and 3-hair follicular unit grafts.
