Revlon One-Step Hair Dryer & Volumizer vs Drybar The Double Shot Blow-Dryer Brush

The Revlon One-Step is the better value for most shoppers: it has a 4-year limited warranty, a genuine ion generator, a cool shot, and 1,100 watts of drying power, and its 4.2 rating from about 1,900 owners reflects a large, mostly satisfied base. The Drybar Double Shot is lighter and more ergonomic, with a 2.44-inch oval barrel that suits shoulder-length hair and volume styling, but its 2-year warranty and three settings give you less to work with. Buy the Revlon for strong drying and a long warranty; step up to the Drybar if weight and hand feel matter most.

• Choose the Revlon One-Step if you want strong airflow, a cool shot to set the style, and the longest warranty in this pair.
• Choose the Drybar Double Shot if you have shoulder-length or finer hair and want a lighter, more comfortable tool for volume.
