What is this product? 5 Curlers in One! Clip-free barrels for smooth curls and waves of any size or style, for fast and easy styling without creases. The Titanium barrels emit powerful far infrared heat from 140F to 430F that ensures safe and even styling for healthy, frizz-free hair. The barrel delivers maximum heat conductibility and offers immediate heat recovery for uniform temperature. Negative ions eliminate frizz and seals the cuticle to create smooth, shiny hair. Far infrared heat preserves moisture in the hair shaft and protects the hair cuticle from damage. Ready to use in seconds, the different size barrels allows you to create any style ranging from tight baby curls to voluminous beachy waves. Temperature remains constant curl after curl, allowing you to work quickly while attaining consistent results. Ionic technology seals the cuticle for shine and long lasting curls that hold for days without any styling products. The clip-free barrels will not tug or break hair.
