Utilizing the correct equipment, it is possible to shave your head with an electric razor. The Panasonic ES-LV81-K Arc 5 is an optimal razor for shaving the head, as it pulls the hair from the scalp up, so that cuts are minimal while shaving.
Try to create a circular pattern while shaving the head for a smooth shave without nicks and cuts. This pattern adjusts to the contour of your scalp and looks the cleanest when the process is completed. Rotary blades are optimal for this type of motion, because they cause minimal tug when circling the head. A popular non-electric razor option is the HeadBlade.
