Follicular Unit Extraction(FUE)
When undergoing an FUE procedure, the entire scalp must usually be shaved in advance. As the FUE technique only allows a surgeon to take every second hair graft from the donor zone, the yield of grafts from the area is lower. Many clinics are forced to go outside of this zone which means these transplanted hairs will become thin and may be lost as a patient becomes older. It can also result in circular scars in the donor region becoming visible over time. The survival rate of grafts in an FUE technique is lower than it is with FUT as the accuracy of the punch tool is lower than that of a technician using a microscope.
Benefits of FUE
There are, however, some instances where the FUE technique may be suitable. Patients who like to wear their hair very short may choose this method as the resultant scars can be less noticeable and more spread out. The FUE method is also useful when only a small area of hair needs to be transplanted, such as in the repair of scars or eyebrow transplants.
