If you’re looking to change up your hair color with a trend that’s going to make a statement, allow us to point you in the direction of rainbow hair. The rainbow hair color trend is going strong, with no evidence of slowing down. In other words: Now is as good a time as any to saturate your strands with color for a truly head-turning ‘do! But where should you start? You need to know what rainbow hair color you should choose and what the best rainbow hair dye is to get your desired look.

Since deciding between blonde hair, brown hair, and red hair can be tough enough, trying to figure out which rainbow hair color is right for you is no easy task. To eliminate the added stress, we’re sharing 31 rainbow hair color ideas—from a pastel option to hidden rainbow hair—for you to achieve your most magnificent mane.

#1. MOONSTONE

Crystal hair colors are trending at the moment, with moonstone hair being one such trend. This hair color idea is a version of hidden rainbow hair. On the outside, instead of a blonde or brown shade, you’ll sport a silver, near-white hue that conceals a handful of soft rainbow colors beneath the top layer. When you wear your hair down, it’ll be your own little secret!

#2. PASTEL RAINBOW HAIR

Is a bold, rainbow hair color a little too intimidating? You can take things down a notch by coloring your mane with a subtler alternative: pastel rainbow hair dye. This hue will still include all the beautiful colors of the rainbow—red, orange, yellow, green, indigo, and violet—but with softer, less saturated versions of each shade.

#3. RAINBOW UNDERCUT

If you want a work-friendly rainbow hair color, a rainbow undercut may be a good option. Since some offices simply aren’t on board with the whole rainbow hair color trend that has taken social media by storm, it’s time to get a little creative. This hidden rainbow undercut is a great way to do that. With an undercut, the bottom third of your hair on the underside of your head is shaved off. 

You can get custom patterns shaved into this section of hair, and best of all, you can create one-of-a-kind colorful looks that will be hidden from sight when the rest of your hair is cascading over it. Until casual Friday, that is—in which case you can show your hidden rainbow hair color off with an updo! (Here’s Everything You Need to Know About Shaving Your Head.)

#4. GEMSTONE HOLOGRAM

Sometimes it seems as though all the fun colors are meant for blondes, but not this one! This hair color embraces a series of gemstone colors placed throughout brown hair. Gemstone hologram hair is known for the way it’s both bright and reflective while remaining true to fall’s darker hues.

#5. HIDDEN RAINBOW ROOTS

We understand that using rainbow hair dye can be a little intimidating. If you’re not quite ready to fully embrace the rainbow trend, consider getting hidden rainbow roots. Only visible when you run your hand through your hair, rock braided hairstyles, or perform the occasional hair flip, this hair color idea is perfect for those who want to experience the magic of a rainbow hair color without going all in.

#6. OIL SLICK

Here’s the scene: You’re walking to your car, only to get mesmerized by the dark puddle of oil you have to step over. As you go to step over it, you notice how the shades begin to change, revealing a gorgeous mermaid-like rainbow of colors. Now picture that same effect on your hair. Oil slick hair is all about having a solid surface hue with rainbow tints blended within it. Most often, the base color will be somewhere along the spectrum of blue smoke to ashy black, with bright rainbow colors of magenta, purple, cobalt, and green painted throughout.

#7. PEEK-A-BOO HAIR

Not ready to shave off a third of your hair but still want to keep your rainbow hair on the DL? Girl, we feel you. Instead, consider getting a peek-a-boo rainbow hair color. To the naked eye, your hair will look totally professional—but as soon as you have the opportunity for a hair flip (or wear an updo), you can let your pretty rainbow hair color stand center stage.

#8. RAINBOW CEREAL HAIR

HOW TO CARE FOR A RAINBOW HAIR COLOR

Hair care for bold rainbow hair colors is two-fold. In short, it really all depends on the rainbow hair dye you use. If you opt for a semi-permanent rainbow hair color, you don’t really need to worry about maintenance, as it will wash out in just a few washes regardless. Now, if you choose to go with a more permanent option, that’s another story. As with all permanent hair colors, in order to keep your rainbow hair color vibrant, there are a few hair care tips you’ll want to follow—see below for those.

RAINBOW HAIR CARE TIP #1: UPGRADE YOUR HAIR CARE ROUTINE

Since you switched things up with a new hair color, you’ll need to follow suit with your hair care products. Stock your shower with a system of nourishing shampoo and conditioner formulated for color-treated hair, such as the L’Oréal Paris EverPure Repair & Defend Shampoo and the L’Oréal Paris EverPure Repair & Defend Conditioner. Once or twice a week, swap out the conditioner for the L’Oréal Paris EverPure Repair Remedy Balm to give your rainbow hair color the extra TLC it deserves.

RAINBOW HAIR CARE TIP #2: TURN DOWN THE HEAT

It’s not just about the products you use, either. Show your rainbow hair color some love by turning down the dial in the shower—after all, scalding hot water can strip your hair of essential oils, which can leave your hair feeling dry and looking dull. Rinse off in lukewarm water instead.

RAINBOW HAIR CARE TIP #3: EMBRACE YOUR HAIR’S NATURAL TEXTURE

Rainbow hair colors look especially pretty when paired with curls or waves, so apply a generous amount of the L’Oréal Paris Advanced Hairstyle CURVE It Elastic Curl Mousse onto damp hair. Scrunch from the roots to ends and let your hair air dry. The end result: Soft, bouncy curls!

RAINBOW HAIR CARE TIP #4: ALWAYS USE HEAT PROTECTANT

There’s no denying that certain styles call for your heat styling tools. Since excessive heat usage can take a toll on your strands, it’s essential to use a heat protectant. The L’Oréal Paris Advanced Hairstyle SLEEK IT Iron Straight Heatspray protects your hair from heat, calms frizz, and seals in shine for healthy-looking locks.
