We think a girl should always keep her options open, so we love this line of no-frizz styling creams from Living Proof. The miracle ingredient is something called PolyfluroEster, which is supposedly the latest thing in anti-frizz technology, blocking the evil effects of humidity. All we know is that it really works, making curls curlier and straight hair sleeker without making it feel greasy or scrunchy. The Wave Shaping, Curl Defining Styling Cream has a lightweight holding agent that adds definition and volume; the Straight Making Styling Cream smoothes split ends and leaves a fabulous shine. $24 each for 4 ounces at livingproof.com
