A scalp tensioner for tensioning a scalp in a donor region of hair grafts, so as to facilitate harvesting of hair grafts. The tensioner includes at least two generally opposed support structures arranged to form an open space therebetween, and plural gripping mechanisms such as a linear array of teeth or needles so as to grip the scalp, with one such gripping mechanism being provided on each support structure. The support structures are slidingly engaged on guide rods, and coil springs coaxially mounted on the guide rods bias the support structures away from each other. The support structures are movable against the biasing action of the coil springs between a closed position at which the gripping mechanisms are engaged with the scalp, and an opened position which corresponds to a scalp tensioning position, and in which hair grafts can be harvested from the open space between the support structures.
