“Tousled hair looks effortless, but this style does require some work,” says Monzon. Apply a thickening mousse to towel-dried hair and spray a volumizer just at the roots to keep hair from falling flat, and then blow dry using a round brush, lifting up at the roots for body. Let your part fall naturally—but aim for it to be 2-3” deep and lined up just after the start of the eyebrow. Take 1.5” wide sections and wrap them around a 1” barrel curling iron starting halfway down the section. Do your entire head and then shake the waves out with your fingers—don’t brush. Rub a dime-sized dollop of Kérastase Crème Nutri-Sculpt between your palms and gently run them along the waves from roots to ends to smooth frizz; spritz hair with a light setting spray to keep the waves from falling out in seaside humidity.
