Check out Lo Bosworth‘s hair, above, while filming “The Hills” along with Kristin Cavallari—now, look a little closer, see the bobby pin? Lo is using it to not only keep her hair in place (a great way to fight the hair fight on windy days), but to also give her side parted hair a slight lift. Rather than letting her hair fall limply, the strategically placed bobby pin gives the parted hair a relaxed, soft vibe. Do it yourself, it takes seconds: Take your already parted hair, and section off the top layers. Sweep ‘em back, making sure you do this softly and don’t pull your hair too taught. Then just slide the bobby pin in about halfway down the length of your hair. For a true don’t-look-twice look, buy the bobby pins that most closely match your hair. Love it.
