Hair Highlights

Scarlett Johansson got decked out in Armani Privé for the Iron Man 2 premiere. Her hair is equally dressy, without looking fussy. We approve, ScarJo.

Nicole Richie's dark brown locks have really grown on us. And we love this simple bun-plus-bangs combo. It feels very easy Parisian chic, mais non?

Naomi Watts, we've missed your always impeccable style while you've been out of the spotlight, hanging with your adorable children. But you certainly haven't lost your touch. We're going to try this side-parted style for our next night on the town.

Rachel Bilson took her Cali-girl style to New York City this week. We love that she looks a little more sophisticated with her hair pinned up in the back, but still totally like herself by letting those curls hang down in the front.

We love how much Kristin Chenoweth we were treated to this week. First, her return to Glee and now, this beautifully classic chignon moment on the red carpet. Forget Hollywood ... Hooray for Broadway!

Jessica Alba happens to be wearing one of our favorite, easy-to-do hair accessories: the skinny headband. It's the simplest way to transform a regular pulled-back bun into a more done look.
