Oil slick hair is a technique that allows brunettes to rock rainbow hair, minus the serious damage that can come with it. Celebrity colorist Aura Friedman invented the look, which incorporates inky iridescent tones of purples, blues and greens, and was inspired by gasoline-laced puddles on a rainy day.
"It's dark, mysterious, rich and, more importantly, the most striking fantasy hair trend with the least amount of damage," says Splat Hair Color Vice President of Marketing and Sales, Helen Crutchfield-Christoni.
Crutchfield-Christoni says for a more vibrant oil slick look, darker brunettes will need to lift their hair to a light brown, but don't have to go to the platinum or light blonde levels that other rainbow hair color trends require.
The color should last four to eight weeks, says Crutchfield-Christoni, as long as you stick to sulfate-free shampoo and conditioners (We like Joico Color Endure Sulfate-Free Shampoo, $14.99, and the Joico Color Endure Sulfate-Free Conditioner, $16.99).
Here, 16 oil slick rainbow hair looks to give you all the inspiration you need for your next salon or at-home color.
