My was hair divided into small one-and-a-half-inch sections curled around medium-size rollers, which hold the sections in place. Depending on the length of the hair, she was able to tweak each curl to make sure we were able to get the appropriate wave. My hair is superlayered, so on the shorter pieces of hair, she created a curl that was looser, and on the longer strands she made one that was tighter.
The hair curler allows for the heat to be evenly distributed among the hair follicle from the top through the middle to the ends, which is key to getting bouncy waves. The iron temperature is also customizable depending on the type of hair, but generally ranges from about 120-140 degrees (another reason why it’s supersafe and nondamaging.).
