January Jones

She got bangs! Back to her familiar blonde after experimenting with dark chocolate, then red and even pink color, January switched up her look yet again with this super trendy bob cut and the addition of some fringe. Swept to the side here, her fringe also wows when worn with a less dramatic side part and more of a sleek treatment.

Did you know: January says she has damaged her hair so severely with her color experimentation that it was "falling out in clumps." "I'm going to have to shave it off and wear a wig," she told Grazia Daily earlier this year. Get tips on making the most of your color appointments.

Sandra Bullock

At the premiere of her new film The Heat, Sandra rocked some serious by elegantly subtle texture and polish. The mid-shaft waves with sleek ends up the ante on the still-popular beachy waves trend clients lust after -- think we'll see this style repeated on the red carpet this summer?

Salon tip: What kind of curling iron are you using to create these waves for client? Invest in a clipless iron, like one of these.

Amy Adams

We've heard for months that the basic black ribbon would be making a major comeback as a hair accessory this season, and this theory is proving to be true. Amy kept her Man of Steel premiere look classic and sophisticated with a trendy, high ballerina bun and a black headband -- think of how cool, literally, she must have been for a special occasion on a summer night!

Product tip: Keep the frizz at bay with reliable spray during the warmer months. MODERN talked with Martin Parsons recently about the launch of his new, highly-anticipated dry, buildable spray, perfect for an updo like this one.

Claire Julien

Long live the halo braid! The Bling Ring star sported a seriously hefty, thick wraparound braid to the movie's premiere, with playful twists and romantic, fallen pieces throughout.

Did you know: Assembly Salon in Beverly Hills just opened a braid and ponytail bar, dedicated entirely to these on-trend styles.
