ATX Clear from Head Blade is a razor specifically for head shaving. You simply shave by driving it forward with the wheels in front. In the rear the shaving head performs the close shave.
If your hair is too long, first use a trimmer before using razor. Soak your head with warm water to soften the hairs. Apply a shaving cream and perform your shave. Rinse your head with cold water and put on a moisturizer.
