The Crwn Joule™ is our most advanced ceramic flat iron, made for anyone who wants polished, salon-quality hair at home. Its 1.25" floating HD ceramic plates move with your hand to keep heat and pressure even across every section, for a smooth, mirror-like finish without going over the same strand again and again.

Choose from four heat settings to suit your hair, from fine to thick and curly, and see your level at a glance on the LED display. The slim plates reach close to the roots for a sleek finish from root to tip, while the 8 ft 360° swivel cord keeps you moving freely.

Thoughtful details make it an everyday essential. It powers itself off after 20 minutes of inactivity, works on universal voltage wherever you travel, and is backed by a 1-year warranty.
