Follicular unit extraction punches are made from a variety of metals. The degree of sharpness varies significantly from one punch manufacturer to another. Sharp punches require less axial and tangential force to penetrate the skin and dissect hair follicles. Minimizing axial and tangential forces helps to reduce the fluid movement of hair follicles during the dissection process. Force compression testing allows the degree of sharpness of any punch to be determined. Follicular groups consist of between 1 and 6 hair clusters. The frequency of cluster size varies from one person to another. The degree of hair splay varies from one person to another. Variation in punch size and incision depth allows the dissection of grafts to be customized to the individual patient and follicle transection to be minimized. Follicular unit excision (FUE) is a safe and efficacious method of harvesting grafts with a low incidence of complications. There are a variety of devices that can be used for graft harvesting and they vary by the type and size of the punch, the method of penetrating the skin, and whether manual, motorized, automated, or robotic. The surgeon has options in picking the device that best suits his/her technique and skills. In the past 10 years FUE has gained in popularity due to rising patient demand because linear donor site scar remains and there is an easier recovery compared with the follicular unit transplantation (FUT) procedure.  FUE remains a surgically more challenging procedure due to many components that have to be closely followed to have low transection of follicular units as well as ensure good healing of the donor area.
