In my opinion, the use of the microscope is essential for the cutting of the grafts. Thanks to it, it is possible to avoid the transections (bad cutting of the hair which stops the regrow of the hair). It allows to cut and to sculpt the grafts making the thin ring of skin on the top as little as possible. It permits also to protect the telogen hair (the resting phase of the fu) which are shorter and transparents. For white hair, the microscope is incontrovertible. With the use of the microscope the transection rate is around 1%, while 10 to 40% of the hair are destryed during the naked eye cutting.
