The Revlon One-Step Hair Dryer and Volumizer is designed to deliver gorgeous volume and brilliant shine in one-step. The unique oval brush design features gently curved sides for smoothing the hair, while the round edges act as a one-step volumizer, creating volume at the roots and beautifully curled ends, resulting in gorgeous salon-like blowouts at home. The hot air brush has tangle-free combination bristles; the nylon pin bristles with comfortable round tips quickly detangle, while the tufted bristles with boar technology gently grip hair to smooth and create shine. Complete with 3 heat/speed settings and a cool option for styling flexibility. Boosted by Ionic Technology to help reduce damage and dry hair fast.
