The AdjustaCurl lets you create any size curls, lift and volume with one roller! It starts out flat and rolls to the size you want, quickly and easily. Roll into our root volumizer to add volume to straight styles, or roll into standard round rollers to create classic curls and waves or smooth styles. With Tourmaline Ionic technology to reduce static electricity, the end result is shiny, silky beautiful hair. And the flat design stacks to store for ultimate portability.
