TheO Pod rollers are perfect for creating lots of fabulous looks. They are available in several sizes so that you can create whichever type of curl that you desire. For longer hair and a bigger lift, select the extra large 60mm rollers, or choose the smaller rollers for tighter curls and more of a defined finish. TheO pod Rollers are light and easy to use; simply use the soft grip to glide them effortlessly into place. What we really love about TheO Pod Rollers is that they heat up from the inside out in less than four seconds, which means less waiting time! They're also hot in the hair rather than the hand. Each of TheO Pod Rollers has a heat indicator spot that shows red when the roller is heated and black if it's cool. We recommend heating one roller at a time to benefit from heat on demand!
