Sleeping on a satin pillowcase helps smooth frizzy hair and minimizes static. The softness of both silk and satin eliminate the friction you get when your hair rubs against a harsher fabric. Another added benefit is that silk and satin help keep your hairdo looking fresher and less “slept on” in the morning.
