Prepare for a revelation: shampoo does not have to be a liquid. And no, we're not talking about the powdery stuff you throw on when you can't be bothered to actually wash your hair. We're talking honest-to-goodness solid-state cleanliness for your locks. J.R. Liggett's Shampoo Bar ($9) handily works up to a sudsy lather infused with peppermint and jojoba oils. And solid means you can toss it into your carry-on without worrying about inviting a full body cavity search at airport security.
