The actress went with sleek, straight hair for the premiere of her film The Roommate. Her center part gives off a slight bohemian vibe, don't you think? To get that shine, be sure to use a shine serum throughout.
Leighton also has long hair so it was nice to see her fake it with a faux bob. To get the look, first curl your hair, tie it at the very end of the strands, roll it under the elastic and tuck toward the nape of the neck. Make sure to spread the hair evenly around the head.
