Did Louis Tomlinson's sister just start the hottest new hair trend?
2015 has been a big year for hair—and up-and-coming beauty guru Lottie Tomlinson wasn't about to let it end without making her mark. Louis' little sister recently debuted rainbow roots, a crazy-cool trend that's , well, just what it sounds like.

What do you think? Would you rock it? What's been your favorite hair trend of 2015?
