Abstract
A method and device for the extraction of follicular units from a donor area on a patient. The method includes scoring the outer skin layers with a sharp punch, and then inserting a blunt punch into the incision to separate the hair follicle from the surrounding tissue and fatty layer. The method and device will significantly decrease the amount of follicular transection and increase the rate at which follicular units can be extracted.
