Olivia Wilde’s tousled bob is perfect for a girls night out or a romantic rendezvous. Natasha Sunshine from Byu-Ti Salon in Santa Monica, Calif. tells us how to steal her style:

1. Begin with clean wet hair. Add a light styling serum, like Pureology’s CuticlePolisher, $28, evenly through the hair.
2. Rough dry your hair until it’s about 95 percent dry. Smooth your bangs over to one side.
3. Using a 1 1/2-inch curling iron, roll your hair in a candy cane fashion away from your face. Spray a light hairspray on your hair before curling each section.
4. Run your fingers through the curls when they’re cool to soften the curls and add a drop of shine serum for that extra glow.
