Curls are back! White Sands Curl Up in Silk Firm Hold Mousse provides a different type of curl pattern. The chemical molecular structure of the ingredients causes the hairs to group together and rope over each other. It also can be used for round-brush styling for volume, and it resists moisture for long-lasting styles. Curl Up in Silk has redefined curls and mousses with its ability to change the curl pattern, provide high shine with no flaking, and leave hair silky and soft.
