Living Proof Straight
Why it's a winner: A proprietary molecule (called PolyfluoroEster) coats the strands to block moisture and helps keep hair straight even on the most humid days. Plus, the lightweight formula is oil- and silicone-free, which means reapplying it to dry hair (to extend the life of your blow-out) won't weigh it down.
