Slightly messy, tousled, bed-head hair has been seen all over the runways. In particular the Fall '08 Dior show, where 60's bouffant style hair a-la Bridget Bardot was the new big look.
While the runway bouffants may be a bit over the top for the everyday, it's easy to re-create a more low key version of tousled sex-kitten hair at home. Just use a comb, a trusty hairdryer, and BigSexyHair's What a tease 'Backcomb in a Bottle' product.
Simply blow dry hair part way, section off the back part of your hair (where you want the extra volume) starting at the crown, lift hair and add product to the underneath. Tease and scrunch up hair, or flip head over and finish blow drying the underneath part of your hair. Flip back up and comb hair over so that it looks a bit more smooth. This product really does add volume so you don't need to add too much!
