Abstract
The extraction of a hair graft from a harvesting area of a scalp employs a hollow punch fitted with an auxiliary instrumentation for separating a target graft from collagen fibrils which resist extraction. A water jet which follows the annular path of the punch as it rotates into the scalp is described as well as a vibrating punch alternative embodiment for achieving the desired separation.
