The new GHD IV Salon Styler has been totally improved: 1 Sleep mode turns the styler off after 15 minutes, if you have stopped using it, and goes to sleep. 2 Universal Voltage allows you to travel the world with your IV Styler and it will automatically work with the local voltage and adjust itself for optimum performance. 3 Shiver Mode combats condensation that can damage stylers. So when the room temperature is below 5 degrees C, your GHD Styler will shut down to protect itself until the temperature rises. 4 Unique Digital Technology improves temperature control for even better styling. 5 Advanced Ceramic Heaters and Aluminium Plates are the ultimate styling surface for the smoothest static-free sheen.
