If you wash your curly hair at the end of the day, coat wet spirals with gel. "Make them crunchy," says Lorraine Massey, co-owner of Devachan salon in N.Y.C. "They will soften overnight and be the perfect consistency when you wake up." If you go to bed with dry hair, remember that friction creates frizz. The fix? Gather your curls into a high ponytail and fasten with a strip of pantyhose, which won't leave any telltale marks.
