Star Hair: Get the Look!

What Not to Wear's hair guru Nick Arrojo tells you how to style your tresses like Jessica, Sienna and eight other celebs. By Serena Kappes


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.
