RevAir Reverse-Air Dryer vs Dyson Supersonic Nural Hair Dryer

These solve different problems. The RevAir is a stretching and drying tool for curly, coily and thick hair: it pulls hair straight through a vacuum wand at low heat, so it replaces a blow dryer plus a brush or flat iron for many owners. The Dyson Supersonic Nural is a fast, quiet conventional dryer with smart heat control and a strong attachment set, and it keeps curl definition rather than stretching it out. Build quality favors Dyson; the RevAir is bulkier and has more to go wrong, but owners with dense natural hair rate its results highly.

• Choose the RevAir if you have curly, coily, thick or frizz-prone hair and want to dry and stretch it straight in one step without high heat or a brush.
• Choose the Dyson Supersonic Nural if you want a fast, quiet everyday dryer that protects the scalp and works with a diffuser to keep your curls intact.
