The Revlon One Step Root Booster is a 1.5-inch hot air brush built to lift hair at the roots and add volume while drying. It pairs a ceramic, ionic barrel with three heat and three speed settings, a cool shot, and a 72-inch swivel cord. It suits people with shoulder-length or longer hair who want salon-style lift at home. Against round-brush dryers from Hot Tools and Babyliss, it is lighter and easier for root work, but it has less power and a smaller barrel than the original One Step Volumizer, so it is a volume tool rather than an all-in-one styler.

Owners like the root lift it gives and find it easier to handle than a round brush and dryer. Many say it adds volume but dries more slowly than the larger One Step Volumizer, and some find the bristles rough on tangled hair.
