For ideal results, we recommend using One 'n Only™ Argan Oil Treatment with your rotating barrel hot air brush to eliminate frizz by smoothing the cuticle for silky, conditioned, and healthy looking hair. One 'n Only™ Argan Oil Treatment helps protect against damage caused by chemicals and excess heat from styling and environmental factors. For more volume: Rotate and wind entire hair section around barrel. Release the rotate button and allow brush to remain in place for a few seconds. Use cool setting to set style. Care & Cleaning:• Unplug the appliance and let cool completely before cleaning it. • Use a damp cloth then clean carefully. Make sure the appliance is completely dry before using again. • The rear filter should be cleaned using a soft brush on a regular basis to help prevent buildup and overheating. This will also prolong the motor life.
