My friends and I like to call it Brigitte Bardot hair: the actress-cum-sex-kitten from the 60s always had perfectly volumized locks. The only problem is that achieving the easy-breezy style is easier said than done. And while some of us are blessed with hair that naturally rises to the occasion, others are stuck with tresses that fall flat. We did some research and it turns out with a little bit of effort and the right products even fine limp hair can be done up — literally. Here are some step-by-step instructions for creating volume that will have you channeling one of beauty's most loved stars. Not to mention a classic look that never goes out of style, whether it's "all about" bangs, waves or sleek and straight.
