The Revlon One-Step is a hot air brush: a dryer inside a brush. You brush it through damp hair and it dries and styles at the same time, giving a smooth, bouncy blowout without juggling two tools. It’s one of the most popular hair tools at its price.
Verdict: excellent value for medium to long hair if you want an easy blowout. It runs hot, so use the lower settings and a heat protectant. Pricier stylers like the Dyson Airwrap or Shark FlexStyle are gentler and more flexible, but cost many times more.
