I like to wash my hair as little as possible. Before you think that sounds gross, it's not. My hair could absorb half of the Atlantic Ocean and still be fine. The best tip I found on preserving a blowout or maintaining any style longer, is to KEEP YOUR HANDS OFF! The oils from your hands and your fingers transfer to your hair creating a big ol' mess. This may be difficult for those of you nervous hair twirlers or flirtatious hair flippers (like myself), but the more you keep your hands off your hair, the longer your style will last!
