Conventional curling irons use a single heater that runs through the middle of the barrel. It heats the barrel unevenly resulting in temperature fluctuations, which means waves don’t set and hair is damaged due to over-styling. The BodyWaver has a hollow tourmaline ceramic barrel that features new T3 SinglePass Radial Technology. This unique innovation incorporates a ring of ceramic heaters that deliver consistent, even, allover heat to every part of the barrel. No matter what your hair length or texture, the BodyWaver will give you fast, flawless, professional-level styling, without causing damage.
