Anti-crease, anti-breakage. Upgrade your hair tie game. THE SLIPSILK DIFFERENCE: Traditional hair ties can tug on delicate hair which can lead to damage and breakage. Slip scrunchies are made with slipsilk, the same silk used in the award-winning slip pure silk pillowcase. Its wide surface area and high-grade silk means our slip scrunchie is designed to reduce those annoying ridges caused by regular hair elastics.
