How to get the look: 1. Apply volumizing mousse all over, and – using a medium-sized round barrel brush – blow-dry smooth. 2. Wrap hair sections around the brush, and blow-dry for five seconds. Blast with cool air to set and unravel. 3. Twist the pieces together to "create loopy, bouncy waves," says Arrojo.
Bonus tip: You can also use hot Velcro rollers – but be sure to cool hair before removing them. "Otherwise, you'll lose the bounce," he says. Finish with hairspray.
