The Classic hair iron features 1inch wide plates that are perfect for those with medium to thick hair that is shoulder length or longer. The Voloom irons are designed specifically to give you lasting hair volume, so you can extend the amount of time between shampoos and colorings. With fewer colorings and shampoos, your hair will start to become even healthier!Ceramic plates paired with a patented checkerboard design work on the under layers of your hair to create a hidden volumizing structure or volume pockets that lift the top layers up and away from the scalp, creating a fuller, more Voloominous look!Adjustable temperature settings from 220 to 395 allows you to experiment and find out what temperature works best for your hair type.
