It happens every year when the weather starts heating up--we all immediately want to lighten up our locks. Whether it's a few sunny streaks or an allover platinum process, light hair seems to be synonymous with summertime! But how do you know if blonde will suit you? Here, we came up with a simple cheat sheet for you. Before making the leap, choose the celeb who's skintone best matches yours, and decide whether she looked best sporting brunette or blonde locks (for example, Ciara was a cute-ish blonde, but in our humble opinion, she's far more striking as a brunette). Go forth, color chameleon!
