The optimized design of the COOLCURL? allows you to easily wrap your hair around the rods by parting them in two equal sections. The length and girth of the curler will be suitable for all hair types, including short/ long, thick/ thin hair. You can easily tie the loose ends that remain after wrapping all your hair around the COOLCURL?on top of your head, thanks to the conveniently placed strings at the bottom of the rods. Filled with an innovative, meticulously engineered memory foam, the COOLCURL? is made to be comfortably worn and slept in. The elastic foam will easily adapt to your head?s shape and movements, while keeping your hair in place. Thanks to the specifics of our filling, you can decide how big or small your curls should be, as the foam will allow you to curl the hair more tight or loose, according to your preferences!?The use of memory foam in this type of product is unique to GLOV?, as we looked for ways to make your heatless hair styling process as seamless as possible.
