Article in English: Since electric shavers work by shearing the whiskers instead of shaving them, you want your hair to be upright and brittle. "Lectric Shave" or other, alcohol-based pre-shave lotions remove excess oil and help the hairs on your face stand up, making for an easier dry-shave. Because the electric shaver shears instead of shaves, it can take multiple passes to capture the hair in the small perforations on the shaver head. Be patient as you go over the desired areas, and remember not to press down too hard. Your electric razor will have hair and dead skin will be caught in the device. Lift the head and dump the refuse into a trash bin. Optionally, put a small amount of metal lubricant on the head of the shaver after it's cleaned out. This will make the head of the shaver run smoothly over the surface of your skin.
