"These piecey waves manage to be pretty and messy.
To get started, apply a baseball-size mound of mousse (like Kérastase Mousse Bouffante) to dry hair, coating it from the roots to the ends until it all feels saturated. (Using a wet product on dry hair produces a slightly uneven, matte finish, which is exactly what you're going for here.)
Blow-dry the hair roughly until the mousse is fully absorbed, then wind sections around a one-inch curling iron, starting at midlength and leaving the bottom free.
Make the ends sharp by running a flatiron over them."
