We don't know if you've noticed, but Zayn Malik and Kylie Jenner have more in common than a killer pout these days - because they're ALL about the changing hair colour.
Oh yes, these two are second only to King Michael Clifford when it comes to switching up their locks, and so we thought it was about time we held a very serious and very important HAIR OFF.
Which sounds a bit sinister, like we're going to scalp them or something. Rest assured, we are not.
Realistically all we want you to do is vote for who rocked each #twinning colour best: green, grey and pink. Because there's nothing we love more than a bit of healthy competition.
Ready? Off you go, then.
