Thanks to its rotating clamp technology, the BioIonic StyleWinder Rotating Styling iron allows you to effortlessly create cascading waves or classic curls in three easy steps: clamp, wrap, and roll. The cylindrical barrel infused with Nano IonicMX works to create healthy-looking more conditioned curls. Signature BioIonic Moisturizing Heat locks in moisture and seals the cuticle while you style, so strands are softer and more conditioned. How do I use It: Press power button to turn on. Press (+) and (-) to set desired temperature. Styling iron is ready when digital screen turns green and displays your set temperature. Clamp hair, wrap around the barrel, use your index finger and thumb to roll the barrel as it winds the hair up into a curl. From BioIonic.
