Once your waves are dry, don’t comb through them — not even with your fingers. Instead, mist all over with a humidity-resistant spray (try: Garnier Fructis Sleek & Shine Anti-Humidity Hair Spray, $4.29) and gently pat your waves down with your hands. “This is ideal to set the hair at the end to create a barrier against moist air,” Prieto says.

If you have some remaining frizz, “spray some hairspray (try: L’Oreal Paris Elnett Satin Hairspray, $13.99) on a small tooth brush and gently comb it over the frizz to eliminate it,” Rizzieri says.
