Get The Oil Slick Hair Color

Pastel hair has been a popular trend for a while. But, season after season, brunettes have watched as their light-haired friends have gone from bright teal ombré to full-on pink without having to completely bleach their hair! The truth is, if you are a brunette, you've probably been feeling a little left out on the mermaid hair trend because turning your dark strands a bright and bold color is normally more tricky than it is for your blonde friends.


Thankfully, there’s a new color technique for darker hair that makes your locks look iridescent: oil slick hair. At first, the term may make you wonder why anyone would want oily hair, but this chic beauty trend actually has nothing to do with actual grease!

Add some blue and green tones to this and you're on your way to oil slick hair

Sometimes called oil spill hair, this is a style that applies a mix of dark blue, green, and purple tones over darker hair, which gives it a shimmery appearance. It’s similar to the pastel hair trend, but its iridescent effect comes from blending darker shades rather than ultra-pale ones. The effect of oil slick hair is a darker spectrum of colors all incorporated together with a bit of edge that looks great with really dark roots.


What makes the oil slick hair color stand out is that it’s mostly about using cooler colors (i.e. blue, green, purple, etc.,) with a hint of one warm color (i.e. pink) worn against dark hair. It’s designed to look dark in certain lighting and shine colorful in the light, like a black oil slick in real life, whereas rainbow contains all the colors in the spectrum, both cool and warm.

How to get oil slick hair

If you have naturally dark hair, this is the perfect way to add a fun and unique color to your hair, without the upkeep! You don't have to lighten it that much to get it there, so your hair will be in better condition. And while pastel shades tend to fade quickly, these deeper colors will last for months. It’s also more subtle than the pastel hair trend, so there is less urgency to head to the salon for a roots touchup the second you get re-growth.


If you decide to get on board with the oil slick hair trend, then book an appointment at the salon but make sure you are using shampoo for colored hair, which is especially developed to be easier on hair that has been treated with color. This type of shampoo not only nourishes your thirsty hair after the color process, but protects your beautiful blues, greens, purples and pinks from fading. If your hair still looks dry, be sure to use styling products like Schwarzkopf göt2b® Defiant® Define + Shine pomade to give you locks the glossy sheen you desire.


If you’re a brunette looking for an edgier hair look this year, then try out the oil slick hair trend for something a bit new and daring the next time you visit your stylist. The bleach-free technique gives dark hair a colorful, iridescent sheen with some amazingly gorgeous results without destroying your strands. The richer jeweled tones of the rainbow make this the perfect look for the season and a score for dark-haired girls everywhere! Want to go the DIY route for oil spill hair?
