Morning Glamour satin pillowcases provide a smoother surface for your hair strands, which reduces matting, breakage, tangling, and snagging. Cotton pillowcases suck moisture from your skin. Satin pillowcases are non-absorbent, helping your skin maintain maximum moisture. They also help prevent wrinkles, allowing you to wake up with smooth, clear skin every morning. The stay-put pocket flap also ensures that these satin pillowcases will stay in place as you rest, ensuring you get the full benefits of sleeping on satin.
