The amika™ 5P Interchangeable Curler features 100% titanium barrels. Titanium is the newest and most advanced technological development used and preferred by professional stylists. Titanium barrels are lightweight, durable and microscopically smooth for silky, snag free styling. The digital display feature lets you set the precise temperature for your hair from 150°F–430°F, guaranteeing perfect results for all hair types and textures. The MCH ceramic heating element emits far-infrared heat which locks moisture in. Negative ions close the cuticle for shiny, frizz-free curls. Included are the 32mm, 25mm, 25-18mm, 19mm, and root lifter. Whichever you use, the result is beautiful hair with unlimited styling versatility.
