Abstract: A functional head is disclosed which may be generally employed in a device for industrial or private use, particularly in a device for beauty care, such as an epilator device. The functional head has at least one first element which has a frictional surface, and at least one second element which is movable over the frictional surface when mechanical friction is overcome. A lubricating device is provided by which a lubricant may be applied to the frictional surface. The lubricant is accommodated in a lubricant reservoir, and the lubricant is transported to the frictional surface by means of at least one outlet opening. An increase of mechanical friction by the movement of the at least one second element over the frictional surface leads to heating of at least parts of the lubricant reservoir.
