A device for carrying out nail corrections, in particular in ingrown nails which are too severely curved, comprises at least one plastics material strip extending in a longitudinal direction. The plastics material strip is rubbery-elastic and longitudinally elastic. At each longitudinal end, it has a hook for engaging around and underneath the nail edge of the toenail to be corrected. The plastics material strip is expandable and, with the hook hooked in, can be adapted with respect to its length to a nail width of the nail to be corrected, so a restoring force due to elasticity brings about an upward force automatically adapted to a degree of curvature of the nail to be corrected.
