The 'oil slick' is the new hair color trend perfect for brunettes

I can't say I've ever looked at an oil slick on the pavement and thought, "man, I'd love for my hair to look like that."

But that's exactly where one celebrity hair pro found the inspiration for her latest hair color trick. "I've been trying to re-create gasoline or oil when it's on the ground and it rains," colorist Aura Friedman told PopSugar of her "oil slick" creation. "I find that when you take a dark purple and a dark green and layer them one on top of the other, you end up with this iridescent feeling."

Also known as the "duck feather," this color trick is made specifically with brunettes in mind because it doesn't require a time-consuming and hair-ruining bleaching process first. "You don't have to lighten it so much to get it there, so your hair will be in better condition," Friedman said of the look that's dramatic enough for the cooler fall and winter months.

Plus, you can make it dramatic with bold highlights.


Or more subtle with a "did she or didn't she get highlights?" sort of glow.


To get the look when you get to your stylist's chair, Friedman recommends asking for a "shiny, blackish base with color peeking through."

The only downside seems to be the time involved with creating the look. According to some Instagram posts I looked at, time in your colorist's chair could range upwards of four hours (!!) to get the right sort of hue.

On the upside? Unlike pastel highlights, these will last for several months, so you won't have to get touchups as often. Between this and the new peacock trend, it looks like I'll be wearing rainbow locks for the foreseeable future.
