We are absolutely obsessed with this latest rainbow hair trend...just the roots are dyed multi-color. Think it's nuts? You've got to see it in action to become a believer – trust us, we weren't into it at first either.
This totally cool look comes courtesy of Louis Tomlinson's sister, Lottie, who showed off the idea in different stages of progress on Instagram.
We were skeptical that painting on rainbow colored hair dye on just a couple of inches of hair at the roots was going to win us over, but the end result is so cute.
Our only question...what does it look like when the hair grows out?
