During follicular unit transplantation (FUT or strip FUT), a strip of the scalp containing a dense amount of hair (typically the back of the head) is surgically cut from the scalp. The scalp is sutured and the donor strip is dissected under a microscope to create slivers that contain the healthy follicles to be implanted. The scalp is then prepped with a skin-punching device so the individual hair follicles can be transplanted to the designated recipient site with fine tweezers. Follicular unit extraction (FUE) surgery is similar, but a medical device is used to remove the donor's hair. The device uses vertical punches to remove the healthy follicle for implantation elsewhere on the scalp. The harvesting process does not produce a lengthy scar, and the harvesting is performed more randomly throughout the scalp. The hair grafts are surgically implanted into bald or thinning areas with a skin-punching device.
