These New Products Make Your Hair Look Its Best Even When It's 100 Degrees Outside

I try just about every Living Proof product that comes across my desk because their research and development is second to none. And their newest launch, Living Proof Perfect Hair Day Heat Styling Spray ($28), doesn't disappoint. It's a multipurpose spray that offers heat protection, makes your style last, and helps your hair stay clean. I can go an extra day before I reach for (Living Proof) dry shampoo. — DD
