Stay On Satin is made from a special patent pending two sided material that is soft inside so it does not slip- and satiny smooth on the outside so it slides against your pillow. The Stay On Satin Extra Large Sleep Bonnet protects your style while sleeping. Wake up with your hair looking and feeling fresh and ready to go. You will cut down on morning prep time by wrapping your hair up and your tresses will be softer and better hydrated. Use with wrapping lotion or foam for best results. Put on when you go to sleep. Remove when you get up.
