The BaBylissPRO Nano Titanium Spring Curling Iron creates loose waves or textured curls. The Nano titanium barrel uses far-infrared heat, heating the hair shaft from within for styling without damage. This iron has 50 heat settings up to 450F & has a turbo heat button to instantly boost heat output for faster results & more defined curls. It is available in 3/4", 1", 1-1/4", & 1-1/2" sizes depending on the desired curl size. This iron uses Sol-Gel technology which transforms nanoscale particles of titanium & ceramic from liquid to solid form, resulting in higher, more consistent concentrations of each. Sol-Gel barrels have a significantly higher percentage of titanium & ceramic compared to conventional barrels. As a result they are stronger, longer-lasting, & more resistant to chemicals.
