How to Get a Mermaid Hair Color How to Get a Mermaid Hair Color How to Get a Mermaid Hair Color

Unicorns aren’t the only mythical creature trending here in 2018—mermaids are also super-popular these days! In addition to gorgeous sea-inspired eye makeup looks, mermaid hair is also a totally fun way to get your feet wet in this multi-faceted hair color trend, so to speak. Defined by shades of blue, green, and purple, this hair color idea isn’t exactly the most low-maintenance. But if you want to turn heads (and fins), it could be a perfect way to change up your hair color for the summer. Here, learn all about what goes into getting a mermaid ‘do, how to get the look at home, and how to care for your bold new color.


This multi-colored hair hue is positively stunning—but it can be difficult to achieve, so it’s best to manage your expectations. If you have brown hair, you’ll need to bleach it first in order for your mermaid-inspired colors to actually show up on your hair. The darker your base color, the longer it may take to achieve your desired look. Further, mermaid hair is all about blending different colors to mimic the way the sea looks—a task that requires a bit of coloring expertise. For both those reasons, it could be a good idea to visit a professional colorist to help ensure you love the way your color turns out. A pro will be able to expertly place the different shades of blue, green, and purple to create a flattering rainbow hue for you.


That being said, it is possible to color your hair like a mermaid from the comfort of your home. Again, if you’ve got brown hair to start with, you’ll need to bleach it first. Try the L’Oréal Paris Colorista Bleach. Once you’re done with that, use the L’Oréal Paris Colorista Semi-Permanent Hair Color in Purple, Blue, and Aqua. Decide beforehand where, exactly, you’d like to place each shade. If you want an even shorter-lived mermaid mane, try the L’Oréal Paris Colorista 1-Day Spray in Blue, Hot Pink, Pastel Blue, Pastel Lavender, Pastel Mint, Pastel Pink, and Purple— all of which will last for one day — or, rather, one shampoo.


Once you’ve colored your hair, it’s important to switch up your hair care routine, as color-treated hair has different needs. Follow the below tips and you’ll be good to go!

1. Switch to a system of shampoo, conditioner, and mask formulated for color-treated hair. Say bye, bye to your regular hair care products and reach for ones that are formulated for color-treated hair instead. Try the L’Oréal Paris EverPure Repair & Defend Shampoo and L’Oréal Paris EverPure Repair & Defend Conditioner. L’Oréal Paris EverPure Repair Remedy Balm

2. Wash your hair in lukewarm water. While it may feel relaxing to splash around in a steamy shower, super-hot water can strip your hair of essential oils. So, the next time you bathe, turn down the dial and wash off in lukewarm temps instead.

3. Rock beachy waves. Put down those heat tools and pair your mermaid hair with some beachy waves—no trip to the ocean required! After stepping out of the shower, towel-dry your hair. Then, spritz on the L’Oréal Paris Advanced Hairstyle AIR DRY IT Wave Swept Spray. Create a braid and undo it once your hair has fully dried. For tighter waves, create multiple braids.

4. Use a heat protectant before applying heat. Want to give yourself an at-home blowout? Spritz on a heat protectant beforehand. Try the L’Oréal Paris Advanced Hairstyle SLEEK IT Iron Straight Heatspray, which helps provide heat protection and sleek shine. After blow-drying create loose curls with a curling iron for a totally mermaid-appropriate ‘do.

Editor’s Tip: To further protect against heat, spritz hair with the L’Oréal Elnett Satin Hairspray Extra Strong Hold with UV Filter for Color-Treated Hair. It will not only create long-lasting hold, but sun protection, too.

5. Schedule touch-ups. If you decided to go the professional route, book your first touch-up before you leave the salon so that you don’t forget. Since mermaid-inspired hair features a whole bunch of different rainbow hues, it can be pretty obvious when your roots start to grow in. If you took the at-home hair color route, keep your bathroom stocked with dye so that you have it on-hand for touch-ups whenever needed.
