Bio Ionic's Long Barrel Curling Iron makes styling easier than ever. Its extended length barrel rapidly fashions contemporary, loose curls and waves. It’s remarkably adept for longer hair, or reaching the back sections of shorter styles. Nanoionic MX and Bio Ionic Moisturizing Heat Technology work in harmony to lock in hydration and seal the cuticle. Expect lasting curls that are conditioned and bouncy, not dull.
