Gemini Hair Is the Bold Hair Color Trend You’ve Been Waiting For
Gemini hair, as it’s called, is a colorful, astrology-inspired look that consists of dyeing your hair two different contrasting colors. Expert hair colorists Jonathan Colombini and Nikki Lee break down the two-toned trend that’s expected to be everywhere.
Shades of blonde and brunette go in and out of style all the time, but one of the hottest hair color trends of the new year so far is all about embracing bold colors. Gemini hair, as it’s called, is a colorful, astrology-inspired look that consists of dyeing your hair two different contrasting colors. We tapped two expert hair colorists to break down the two-toned trend that’s expected to be everywhere.
What Is Gemini Hair?
Named for the twins of the Zodiac, gemini hair is a two-toned hair color look in which one half of your head is one color (often your natural color or close to it) and the other half is a bright, contrasting shade like red, blue or pink. The key to nailing the striking look is to split the two colors along the part of your hair. Duality is the whole point.
According to Jonathan Colombini, Celebrity Hairstylist & Creative Director of Style & Color for L’Oreal Paris,
“This hair color trend has been popular for decades — now, the ’90s grunge presence is still prevalent, but with an elevated look.”
He credits celebrities with bringing the look back in recent months.
“I think Gemini hair is becoming popular because it’s a fun change and allows you to try out two different colors at the same time,” says Nikki Lee, co-owner of Nine Zero One Salon, “almost like if you were wearing different wigs with different outfits and moods.”
How to Try the Gemini Hair Trend
Since this statement look is a bit of a long-term commitment, it’s important to know exactly what you want when you head to the salon, says Colombini. “If you have never dyed your hair a bright color before, I would start with something on the more natural side and ease into it,” recommends Lee.
When it comes to choosing your colors, you can really have fun with it and try whatever you want. However, Lee advises that you think about how dark your natural hair color is when making your decision. “If you have super dark natural hair, to avoid damage from bleaching prior to the color, I would go with a darker or warm-toned bright color,” she says. “If you have light natural hair, it’s easier to do light and bright tones because your hair can easily be bleached to white before applying the color.”
Otherwise, the choice is yours. If you’re not sure where to start, Colombini likes neons paired with black hair and copper shades for brown or brunette hair. With platinum hair,
“any color is going to be contrasting, which is the vibe,”
he notes. “From black to pink, you can’t go wrong.” If you want to test the look at home before taking the plunge, the L’Oréal Paris Colorista Semi-Permanent Hair Color collection has great pink options.
As far as post-salon maintenance, Colombini warns that it’s common for hair colors to bleed together. Since the key to the Gemini hair look is clean contrast, he recommends sectioning off your hair by color when you wash it and washing each color separately.

Best Overall Hair Dye for Dark Hair
IGK Permanent Color Kit
PROS
• It doesn’t have a strong smell from ammonia
• Color looks realistic
CONS
• Some reviewers felt there was not enough hair dye to cover all their hair
One of my biggest issues with DIY hair dye is the lack of dimension in the color; many can feel like they fall flat, which makes hair look kind of blah—especially if you have darker hair like me. To the rescue: this color kit, formulated by the brilliant colorists behind IGK salon. They made it their mission to create salon-level dimensionality at home. Additionally, this permanent formula also conditions the hair with hydrating squalane and strengthening bamboo extract.
THE REVIEWS: “This is my new favorite hair dye," writes a reviewer. "The brown color is gorgeous and my hair came out softer and more healthy than it was before I colored it. "I definitely won’t go back to any other hair dye after using this," writes another tester, adding that "the results are incredible."

Best Dark Hair Dye for Touch-Ups
dpHUE Color Boosting Gloss + Deep Conditioning Treatment
PROS
• Helps buy you time between hair color appointments
CONS
• The darker colors can stain your hands or shower walls
Nothing cramps my style more than when my hair color starts to fade. Like, when it becomes dull and lackluster but it’s not quite time for a full color touch-up. This in-shower hair gloss is the answer. It’s basically a conditioning mask, but infused with color pigments to enhance your color for that fresh from the salon look (without the fresh from the salon price tag). I shampoo first and then leave this on for about ten minutes to reveal smoother, shinier hair for up to four weeks.
THE REVIEWS: “This deep conditioning treatment is the best," writes a tester. "It gave my hair an amazing color boost and made it feel very soft and look very shiny too—I would 10/10 recommend this product.”

Best Bright Hair Dye for Dark Hair
Overtone For Brown Hair Coloring Conditioner
PROS
• Temporary formula allows you to play around with trendy colors sans commitment
CONS
• Some reviewers mentioned the color bleeding during application
Newsflash: You don't need to bleach your hair before experimenting with a fun, vibrant hair color like rose gold or bright blue. I love using Overtone for playing around with trendy shades without lifting my natural color. Their pigmented conditioners (they're crafted specifically for brown hair) come in seven shades, from rose gold to green, and alter the tone of your hair for up to ten washes.
THE REVIEWS: “This stuff is the best," one reviewer writes. "I mixed the purple and pink for brown hair in equal parts and it turned out amazing!”

Best Dark Hair Dye for Sensitive Skin
Clairol Nice'n Easy Permanent Hair Dye
PROS
• Budget-friendly option
• Good for those with reactive skin
CONS
• Some shades can be hard to find in-stock
This one's for all you guys with allergies or super sensitive skin. It took Clairol twenty years of research, but they crafted a molecule called Me+ that reduces the risk of allergies significantly, and this formula touts that very molecule. This is a good reminder that no matter what hair dye you choose, you should always do a small patch test first to make sure you don’t have a reaction.
THE REVIEWS: “So far I am really impressed by this hair color—and that is saying a lot for box color," one review reads. "This is easy to apply and the color is nice for my hair—plus the scent is quite pleasant too," another tester writes.

Best Dark Hair Dye for Covering Grays
Madison Reed Radiant Hair Color Kit
PROS

This kind of service is essential if you’re a newbie, or you’re just in need of a little extra help on your at-home hair coloring journey. Plus, their permanent formula packs super-pigmented color that covers even the most stubborn of grays. And it’s eight-free, so it’s formulated without certain ingredients like ammonia, but with nourishing ones like keratin and argan oil.
THE REVIEWS: “This is the only hair dye I'll use at home," writes a tester. "I use the black dye and it seamlessly covers my grays and looks very natural too."

Best Wash-Out Hair Dye for Dark Hair
Good Dye Young Poser Paste Temporary Hair Makeup
PROS
• Temporary color can be easily washed out
CONS
• Some reviewers didn’t like the waxy texture or thickness

It’s a paste texture that offers both hold and color and is perfect for achieving peek-a-boo strands or an ombre effect You can always layer on for more vibrancy, but be mindful as you apply because the formula dries quickly and has a thick consistency. When you’re over it, just wash it out!

Best Dark Hair Dye for Targeted Application
Hally Hair Shade Stix
PROS
• Easy to apply and rinse out
CONS
• The spoolie can get caught in thick, curly hair
The unique spoolie applicator allows you to brush on color sans mess. Give yourself bold highlights in orange, purple, pink, blue or red. The tube also has a handy compartment on the bottom where there’s a hidden comb that you can use to sheer out the pigment or to distribute the color through the length of your strands. The spoolie is great for smoothing down flyaways, too, if you want to keep baby hairs out of your face with a little pop of color.
THE REVIEWS: “I love how easy this color is to use and how quickly it washes out," one reviewer says. "The hot pink color payoff on my super dark hair was incredibly impressive," writes another tester.
Can you dye dark hair at home?
Yes, you can dye your dark hair at home—but there are a few rules to keep in mind. The first? "Don’t attempt to bleach or highlight your hair at home because you don't know what color it will lift, or lighten, to,” says Balding. There's a ton of science and skill behind hair bleaching and it should absolutely be left to the pros.
The second? Don’t bother using a semi or demi-permanent dye in a lighter shade than what you have because it’s not going to do anything—except maybe tint your roots if they’re lighter or gray.
What hair dye works best on dark hair?
“If you want to stay dark and just add a little shine and warmth, opt for a semi or demi-permanent hair dye,” says hair colorist Johnathan Colombini. “This will prevent any brassy undertones from peeking through and will keep your hair healthy and damage to a minimum.” And make sure to read instructions because depending on the color you want (like some of the real vibrant ones), the site or packaging may say that it’s best to use it on pre-lightened hair.
What hair dye shows up on dark brown hair?
“Permanent hair color is going to be your heavy hitter in giving the most visible results,” says Colombini. That said, there are plenty of temporary options that will show up on your dark hair, like if you're going a shade or two darker or adding in a deep pop of color, like burgundy or midnight blue, to your hair.
Which hair dye is least damaging?
As a rule, any hair dye with words like "moisturizing“ or "nourishing" will be gentler on your hair, says Balding. In general, semi or demi permanent hair dyes with low ammonia and peroxide as well as gloss formulas are usually the least damaging, says Colombini.
How to choose the best hair dye for dark hair:
Keep it in the (color) family.
If you already have dark hair, there are plenty of options for you to try in terms of color. There is always the opportunity to go darker. Just realize that the color on the box may come out even darker than expected, so if your hair is medium brown, you don’t necessarily need to go for the darkest shade to see a dramatic result. Instead, try playing with tone. You can try a more blue-based shade for something cooler and ashier or a more red-based one for something warmer and brassier.
Try out something temporary.
The easiest way to skip bleaching is to try some of the temporary colors that are intended for use on dark hair. Since they’re not permanent, you don’t have to worry about causing any long-term damage to your hair, so they’re good for experimenting. If you decide you do like a brighter shade, I highly recommend going to a salon and leaving the lightening to a professional before committing to a more permanent pastel or vivid color.
Know your color quantity.
Many reviewers for boxed dyes complain that they didn’t have enough color for even shoulder-length hair, which is why Colombini recommends buying two boxes of the same hair dye when coloring the your entire head.
As for application, you should always start with the roots first because that hair is the healthiest and won’t soak up the dye as quickly– it’s also likely the part of your hair that needs the most color. Save your lengths and ends for last because they tend to be drier and more damaged, which causes them to absorb the color much quicker. Doing your whole head at once is an easy way to wind up with a line of demarcation from where your grown out hair was previously colored.
