Dryer Brushes

A dryer brush merges a round brush and a blow dryer into one tool, so one hand does the work of two and the tension-and-heat combination that makes a blowout smooth happens almost automatically. The differences that matter are barrel shape and size, airflow and wattage, heat settings, and bristle design, because those decide volume versus sleekness and how much heat stress your hair absorbs.

The ten tools below include oval volumizers for body, round brushes for shorter layers and root lift, and heated-comb hybrids for straighter finishes. Note that the Revlon One-Step Volumizer anchors our separate hair-dryers topic; the Revlon pick here is the distinct Root Booster model. Use these tools on towel-dried, roughly 80 percent dry hair for best results and least damage.
