Embellished Tresses
When co-hosting an L.A. runway show with Pete Wentz last month, Nicole Richie topped off her wavy tresses with the Seven Strand Headband from her House of Harlow 1960 line.
Loose Layers
Cameron Diaz's character shaves her head in My Sister's Keeper, but at the movie's New York City premiere, we witnessed the return of the actress's below-the-shoulder strands. Layered and straight yet slightly mussed, Diaz's style looked effortlessly sexy.
Tucked-Under Tresses
Kate Bosworth embraced the au naturel look during a recent night out in Los Angeles, letting her golden waves fall loosely in the front, while tucking the remaining hair under at the nape of her neck.
Textured Chignon
For a casual-chic look, Jessica Alba rocked a low chignon with hair slightly ruffled and lifted at the crown.
Fishtail Braid
At the Cannes Film Festival to promote her movie Inglorious Basterds, Diane Kruger accentuated her little black dress with an off-center fishtail plait.
Breezy Bob
While her twin sister has been wearing her strands long and wavy, Ashley Olsen traded in her lengthy tresses for an asymmetrical bob, seen here at the Los Angeles premiere of The Hangover.
Cascading Pony
At the MTV Movie Awards, teen queen Miley Cyrus looked the part. Securing the bulk of her thick curls with a hair band in back, Cyrus let her long bangs softly frame her face.
Lightened-Up Color
Brunettes and blonds aren't the only ones who get highlights for summer; redheads like Isla Fisher lighten up too. For Bruno's UK premiere, Mrs. Sacha Baron Cohen took her deep scarlet strands to a brighter strawberry hue.
Side Twist
At the MTV Movie Awards, city girl Whitney Port twisted a small section of hair above her left ear for a boho-chic finish.
Beachy Waves
Hayden Panettiere made the right choice when she went curly for Spike TV's Guys Choice Awards; her beachy waves were worthy of hero worship.
Super Straight
No one can go from curly to pin-straight like Alicia Keys can: For the White House Correspondents dinner last May, the songstress took her tresses from naturally wavy to enviably sleek.
Half Updo
Keeping flyaways off her face with a dark elastic headband, Megan Fox pulled her tousled tresses into a half updo for the West Coast premiere of Transformers: Revenge of the Fallen.
Mini Buns
Gwen Stefani loves wearing buns—and lots of them! For No Doubt's Today show performance, Stefani fashioned her hair into perky twists that scream summer fun.
Sweetly Shorn
In preparation for an on-camera hair shave in her upcoming movie, Nappily Ever After, Halle Berry has gradually snipped her strands to a sweet, no-fuss pixie ideal for summer.
Messy Chic
To complement her casual-chic maxidress, Eva Mendes opted for similarly low-maintenance hair at The Hangover premiere. Her not-quite-wavy, not-quite-straight tresses appeared perfectly air-dried and slightly tousled.
Loose Pony
After securing what she could of her cropped hair, Michelle Williams let the rest fall around her face for a fashionable faux bob.
Tight Ringlets
To say that her character on 90210 is slightly unstable is an understatement; in real life, the only thing crazy about AnnaLynne McCord are her sexy, spontaneous curls.
Romantic French Twist
As the headliner for New York City's Shakespeare in the Park production of Twelfth Night, Anne Hathaway explores her masculine side. But at the after-party for the play's premiere, the Oscar nominee wore a fairy-tale French twist with delicate tendrils framing her dewy skin.
