While I’ve never truly subscribed to the idea that blondes have more fun, they do have infinitely more options when it comes to mermaid hair color trends. From dreamy pastels to galaxy-inspired ombre, these colors were designed for people with flaxen hair. But now there’s a rainbow hair color trend just for brunettes that doesn’t require bleaching.

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.
Here, 16 oil slick rainbow hair looks to give you all the inspiration you need for your next salon or at-home color.
1. Pop of Red

While the traditional oil slick colors play up violets, greys, blues, and greens — make the trend your own by incorporating a strand of red here and there. It’s the perfect contrast for making blue eyes pop.
2. Oil Slick Ombre

So what if you’re a naturally light brunette? You can still pull off the trend by adding subtle red highlights to the green/purple/blue scheme — and it looks just as beautiful in a subdued tone. It instantly jazzes up your natural look, and there are zero bleachings required. Winning (does a happy dance).
5. Lazy Chic

Regular touch-ups? No, thanks. This oil slick ombre allows ladies to go longer between hair appointments by keeping the color strictly to the ends (if you’re working with your natural hair color at the root, of course). Just be sure to use a color-safe shampoo and conditioner, to ensure your dazzling strands stay fabulous.
6. Mermaid Mane

This ‘do is pure mermaid magic. Play up vivid colors by adding some texture to the hair. Grab a 1-inch curling iron and, starting at eye level, curl hair, alternating directions with each section until your whole head is beaming with bouncy, colorful tendrils.
7. Colorful Contrast

Could her hair be any slicker? (Hehe.) Her dark and shiny mane works as a perfect contrast against the vivid pops of color and plays up the chic, “inky” look that oil slick hair calls for. And they say blondes do it better.

8. Magical Mane

Her head is just blossoming with awe-inspiring hues. While her hair looks magical, that enchanting color didn’t take without a little help from the bleach. This brunette beauty had to pre-lighten strands before achieving this style. But hey, it’s clearly 100 percent worth it.
