Brilliantine, $20

For that starlet, just woke up in a stranger's bed, threw on a couture gown and walked the red carpet look, Bumble and Bumble's Brilliantine does the trick. Just a dab of this polish makes hair look separated, languid and glossy, but not overtly shiny. Think of Sienna and Cameron's slept-in, messy looks. No blowdryer, flat iron or fussing necessary. Bumble and Bumble.
