Wet to dry straightening with air. No hot plates. No heat damage. Airflow is projected downwards at a 45 angle to create the tension needed to align hair for a smooth end style – with less damage and breakage. Glass bead thermistors, located in the machine arms, regulate airflow temperature up to 30 times per second to prevent heat damage and protect hair’s natural shine. LCD screen features a high-definition color display that shows airflow and temperature settings for easy reference when styling. Lock feature allows you to slide the button to lock and unlock the arms of your machine. Use with the arms locked to gently pre-dry hair and create volume from the roots. Auto-pause occurs after three seconds of inactivity. Your machine will automatically pause to save energy. Simply move the machine to restart the airflow. Compatible with 120 Voltage.
