the coolest girls with rainbow hair.
OK, so we know that rainbow hair is nothing new. We get it-- Gwen Stefani first rocked turquoise raver buns at the MTV Awards decade ago and ever since the '90s, My Little Pony locks have become the beauty trend that just won't die. But then again, who says it has to? Definitely not Kate Moss, who made washed-out pink first cool decades ago, or even Allison Mosshart, who's making it cool today. Everyone can use an extra dose of neon in their lives (especially on a Wednesday morning), so we've rounded up the ultimate candy-colored hair icons in the gallery here. Check out our faves, and vote for yours on Facebook.
