Abstract: A shaving device that includes a shaving head intended to be moved in contact with the skin, where the head has at least one blade made of conducting material having a cutting edge suitable for cutting hairs. The blade is supplied electrically by a current source suitable for transmitting a current generating an electrolysis effect at the root of a hair. A shaving method employing current transmission by the blade is also described.

Abstract: The anti-friction strip of the invention for a discardable razor is obtained by extruding a polymer mixture comprising an insoluble polymer material and polyethylene oxide. It has an initial coefficient of dynamic friction (KD) of the order of or less than 0.2. The mixture for extrusion includes, as its polyethylene oxide, only a substance whose mean molecular weight is greater than 3.5 million. The strip is preferably obtained by extruding a mixture comprising polystyrene and polyethylene oxide having a mean molecular weight greater than 4 million, and in particular a single polyethylene oxide having a molecular weight greater than 7 million. The invention also provides a shaving head having the above-specified anti-friction strip fixed thereto by ultrasonic welding.
