Overdirecting is a styling technique to create extra body, volume and height. Position the cylinder side toward your scalp. Hold the rotating cylinder against a section of hair, pushing in the opposite direction of where the section of hair is to fall, hold for 3-5 seconds. Then slowly glide the InStyler®, still pushing in the opposite direction, maintaining tension and keeping the hair tight against the cylinder, through the entire section of hair to the tips.
