We all know that rainbow hair was THE hair trend to sweep Insta feeds in 2015. From moonstone hair to hypercolored locks, it feels as though we’ve possibly seen it all — and even into 2016, it’s a trend that’s showing no signs of slowing down. But for those who want to rock that brightly colored cartoon-y look without being too in-your-face about it, there’s a new secret rainbow hair style trending hard right now, and we are in LOVE.

Introducing: underlights. A subtler, sneakier take on rainbow hair, this look focuses all rainbow power on the underside of a person’s mane. The top remains either natural or dyed a more conventional hue, making this secretly bold ‘do totally workplace friendly. When you decide to let your rainbow colors come out and play, the style’s peekaboo color blast feels right at home in a sloppy topknot or poking out from under a ’90s girl half-pony.


And if you want to test this look out in a really cheeky way, you could always whip out your fave matching colored eye or lip pencils and dot yourself a spray of complementary rainbow freckles. You only live once, amirite?
