fit into small, needle-made incisions without any need for removing tissue. This preserves the elasticity of the scalp and holds the tiny grafts snugly in place. After surgery, the snug fit facilitates wound healing and helps to ensure that the grafts will get enough oxygen from the surrounding tissue in order to maximize their survival. Ability to perform large hair transplant sessions There are four reasons why the follicular unit transplantation procedure allows a hair transplant surgeon to transplant large numbers of grafts in each session: The hair restoration can be completed quickly so that the patient has minimal interference with his/her lifestyle, A larger number of grafts can compensate for the shedding that frequently accompanies a hair transplant, called telogen effluvium, Using large numbers of grafts in each session preserves the donor supply by reducing the number of times incisions are made in the donor area, Extracting large numbers of grafts provides sufficient 1- and 2-hair grafts to create a soft frontal hairline and enough 3- and 4- hair grafts to give the patient the fullest possible look.
