Lottie Tomlinson – little sister of Louis – caught our eye last week when she debuted some amazing day-glo coloured roots on Instagram.
And while we love the edgy look, sometimes it's just not kosher to dye your roots six different colours.
For an out-there look that won't last weeks, we're seriously considering giving glitter roots a go.
