Meet The Lunata Cordless Hot Brush Introducing the world’s first cordless, full-sized hot brush that reaches 450 degrees Fahrenheit. Use it on dry hair, after blowdrying, to smooth hair from root to tip. Perfect to prep hair for further styling, or on its own for beautiful, healthy looking, smooth hair. Ceramic mini plates feature negative ions that close the cuticle for optimal shine and frizz control. And the best part? No cords! Use it cord-free, or plugged in if you forget to charge it (happens to the best of us).
