The latest in Tourmaline Technology from Helen of Troy is here in this Bed Head Professional Tourmaline Nano-Ceramic Curling Iron. This innovative curling iron uses the power of Tourmaline to generate far infrared heat with massive amounts of ionic activity to smooth the hair cuticles and create curls without damage. Durable, Nano-Ceramic Barrel delivers negative ions to create shiny more manageable, longer lasting curls. Rheostat Dial Heating up to 400 degrees F allows for total curling control and 30 second heating with instant heat recovery eliminates damaging hot spots. Additional features include Fiber Optic Indicators, a built in safety stand and a cool tip to keep those fingers safe. All you need to do is pick your barrel size and the curls of your dreams are yours. We suggest the 1-1/2” size for large curls and waves with lots of volume and shine.
