Abstract: A comb suitable for use as a teasing comb in hair styling is motor-operated so that consistent, high quality results are obtained without tiring the service provider. The motor is light-in-weight and is electrically-powered so that it can be housed in the comb handle. An elongate rocker arm is mounted for pivotal movement so that a leading end of the rocker arm is oscillated when the motor oscillates the trailing end of the rocker arm. The teeth-carrying part of the comb is mounted to the leading end of the rocker arm. At the trailing end of the rocker arm, rotary motion of the motor's output shaft is translated into an oscillating, arcuate motion and at the leading end of the rocker arm, the oscillating, arcuate motion is translated into a straight back-and-forth motion having no arcuate component to simulate a manual teasing motion. In one embodiment, the comb is made of a deionizing material that inhibits the buildup of static electrical charges on the comb as the comb strokes the hair.
