Revlon One-Step Hair Dryer and volumiser for mid to Long Hair (One-Step, 2-in-1 Styling Tool, Ionic and Ceramic Technology, Unique Oval Design) RVDR5222

The Revlon One-Step is a hot air brush, not a hair dryer. You dry and style in one pass instead of blow-drying first and then going back with a round brush. 26,000+ reviews on Amazon UK and it's been one of the top-selling styling tools for a few years running.

What it does

The oval barrel smooths hair at the roots and curls the ends inward as you pull through. Salon blowout results without needing to coordinate a dryer in one hand and a brush in the other. Revlon claim 22% more shine and 36% less breakage compared to using a separate brush and dryer, based on third-party testing.

Ionic and ceramic tech are both built in. The ions cut frizz, the ceramic coating distributes heat more evenly so you're not blasting one spot. Our what is ionic hair dryer article goes into the science behind it.

Who it suits

Mid to long hair. If your hair is short or pixie-length, the barrel is too big to get close to the roots. Fine to medium thickness works best. On very thick or coarse hair it still works, but you'll need smaller sections and more patience. Our best hair dryer for thick hair guide has options with more power if that's you.

Worth noting for curly hair: it smooths and straightens more than it defines curls. If you want to keep your curls but tame the frizz, a diffuser on a regular dryer does that job better. Our how to use a hair dryer diffuser guide walks through the technique.

What it doesn't do well

Not a replacement for a proper dryer if you just want dry hair, fast. The airflow is weaker than a standalone 2200W dryer because it's pushing air through a brush head. Expect 15-20 minutes for mid-length hair, longer for thick.

The barrel gets hot, and there's no cool shot button on this model. Keep it moving through sections rather than holding it in one place. Some people miss the cold air blast for setting a style, but at this price you're making trade-offs.

Price

Usually under £30, sometimes under £20 in sales. Our best hair dryer under £50 roundup puts it against traditional dryers at the same price point. It also appears in our best budget hair dryer list.
