Stylist Mara Roszak created these easy, loose waves in four steps:
"Apply a drop of Kérastase Sérum Oleo-Relax to the mid-lengths and ends along with Kérastase Ciment Thermique.
Part hair in the middle with a clean part and blow-dry smooth with a medium-sized round brush, keeping some volume and movement.
With a one-inch barrel curling iron, rotate the direction of each section around the barrel, leaving the ends out.
Gently tease the crown and spray Kérastase Double Force Hairspray all over hair, breaking up the waves with fingers for an undone look."
