Hottest celeb hair trend of the moment

In Cannes, The Artist star Bérénice Bejo displays dramatic flair with half her chestnut hair neatly slicked behind her ear.

Hilary Swank pairs an impressive tousle of romantic waves with her half-back style.

Julianne Hough goes for a deep part and lots of volume at the Met Gala.

Dark Shadows lead Eva Green wows with her jet-black, side-swept hair—paired with appropriately blood-red lips—at the film's premiere.

Cutie Kristin Kreuk—beloved for her role in Smallville—sported the new 'do in New York City.

Erin Wasson rocks a severe version of the look by sweeping nearly all her hair to one side.

Chinese actress Li Bingbing—set to star in her first English-language film, Resident Evil: Retribution (out this fall)—shows how beautiful this look can be when worn with sleek and shiny waves.

January Jones does the slick thing, but opts to keep the rest straight and blunt, proving this style can be worn by ladies with shorter locks.

Looking suitably elegant at a Cannes bash, Jada Pinkett Smith followed the side-back trend while clad in a shoulder-baring, glittering mermaid gown.
