Sleeping beauties with curls have a double challenge: preventing frizz from forming while also trying to keep the spring in their coils. According to Barr, friction causes frizz, so if you decided to sleep on a satin pillowcase for your skin, you'll be happy to hear that your curls will enjoy it as well: "Soft satin pillowcases reduce friction and are pretty luxe to sleep on as well!"

To keep ringlets intact and defined overnight, Barr advises applying a small amount of smoothing cream to your hair in sections, allowing the product to soak in overnight: "If you are worried about the product, loosely tie on a scarf or handkerchief to protect your hair and keep it off of your pillowcase and sheets." Maybe not the sexiest bedtime ensemble, but to avoid the whole wash/scrunch/twirl routine in the morning, we'd say it's worth it to sport the scarf. If curls look at all limp,just add a little bit of curl spray to bring back the spring factor.
