The Babyliss Pro Ultrasonic Cool Mist ultrasonic steam straightener is a professional ultrasonic steam straightener with unique ultrasonic technology that reduces the impact of high temperatures on the hair. This straightener combines three unique technologies simultaneously. Ultrasonic technology hydrates the hair, reducing friction when in contact with the plates and leaving it perfectly straight. Thanks to EP 5.0 technology, heat is distributed evenly across the entire surface of the plates. These are three times harder, more durable, and smoother. Advanced Heat Management System technology allows the appliance to heat up instantly, reaching very high temperatures, ensuring temperature stability with an accuracy of 0.5°C. It has high reactivity and regenerative capacity. This straightener is suitable for professional use. Only distilled water should be used in the straightener.
