Hair dryers and volumizers tested for heat, airflow, and hair-health impact.
After 8 months and 110 hours of blowouts on three hair types, the Revlon One-Step Volumizer Plus 2.0 remains the budget hair tool I recommend most often. We measured 280ยฐF (138ยฐC) on the high setting, surprisingly gentle for a $49 dryer-brush, and salon-quality at-home blowouts in 8 minutes flat on shoulder-length hair. It's not the Dyson Airwrap, but at one-twelfth the price, it doesn't pretend to be.
