Mermaid hair is a hair color trend that infuses two or more pastels or vivids onto long, beach-wave hair. Luscious lengthy hair plus waves plus a whole lot of magical fashion colors. Colorful hair dye is on track to becoming everyone’s next favorite hair color! Multi-toned pastels and vivids make this style intensely fun to wear, aside from all the attention that you’ll receive.

Tight, small curls to soft, big waves are the usual styling to complete the display of different fashion shades. Length can also allow you to create flawless transitions of color and intensity.

With gorgeous hair comes great responsibility. Be ready for multiple bleach procedures and a multitude of patience for your desired colors to appear on your strands. Post-coloring care, such as using protective hair products and occasional salon trips for upkeep, is a must!

Before your next hair appointment, check out these inspiring images of on-trend mermaid hair colors.

Sapphire teal waves are a statement hairstyle. They are beautiful but finicky. Be prepared to see your stylist more often with any fashion hair color. Fashion colors aren’t permanent. They fade fast, especially if you follow only some of the rules. Here are some rules you should try and follow: wash in cold water, keep washing to a minimum, keep heat settings on hot tools lower, don’t wash your hair for at least 48 hours after having color done, and ask your stylist what shampoo and conditioner they recommend.

Long mermaid hair is a hair color that has teal, purple and blue colors painted in. It’s a great option if your hair is naturally dark and can only lift to orange-yellow.

The shades of mermaid pastels all-over the hair give a vivid and exciting finish. It’s a great way to express yourself and get tons of compliments. The techniques used to achieve the look include split color and color melting. As for the upkeep, I suggest washing the hair with a sulfate-free shampoo in cold water.

#25: Bold Blue and Purple Mermaid Hair

This is a mermaid hair color with a purple-y sunset hue and a beautiful blue ocean hue. The amazing thing about this is how you can formulate underlying pigments and still achieve the color for the desired tone.

My #1 tip for ladies who want to try this hair color is to go into a detailed consultation with the stylist. You have to talk about your wardrobe if you wear makeup, and how you style your hair. Furthermore, it’s also important to know your face shape to learn how your stylist can section and layout the color so you see that contrast when you look at it at eye level.

#26: Pink, Purple, Green and Blue Rainbow Mermaid Hair

This mermaid hair features a variety of colors, such as bright pinks, purples, greens, and blues, then rainbow tones at the ends.

“The color choice for the hair was beta fish-inspired,” says hair colorist Tori Briggs of Rocky Mount, NC. “The dark blue, light blue and minty green were chosen as the main colors with sections of pink, purple, and neon green riddled underneath and around the facial frame,” she explains.

When trying to achieve a color melt, the goal is to create movement within the hair that would be calming on top and then open into bold pops of color. The dark blue shadow root helps tremendously with how the hair transitions during the grow-out or fade-out stage.

If you want to opt for rainbow mermaid color hair, Briggs wants you to consider your personality and skin tone. “If you’re quiet, choose pastels and softer tones for that laidback vibe. And if you’re bold, then naturally go with vibrant colors.”

#27: Sea Foam Green Mermaid Short Hair

This sea foam green mermaid style by stylist and salon owner Rachel Ringwood of Florida is an elegant punk. The transition from a high upkeep regrowth line, aka bleach, and tone with magenta creates more of a low-maintenance, sassy dimensional color.

“Investing in good products is a game-changer for all your mermaid hair ideas! Use sulfate-free, paraben-free, sodium chloride-free products, less alcohol with styling products, and less heat, as you might melt your color right off,” Ringwood warns.

Bright colors have changed the game, and women are becoming more opening minded in different businesses. Art, colors, and self-expression flow so well together, so why not embrace them in all ways?

#28: Wave-Crashing Silver, Blue and Purple Mermaid Hair

This blue-purple mermaid hair color features silver highlights to add a lighter shade to the middle, which gives hair a dimensional ombré look! The darker root and end color make the mid-area pop a little more!

“Fashion or vivid colors are a commitment,” says hair colorist Courtney Alexander of Lebanon, MO.

Low-heat settings on hot tools and a good heat protectant like the Kenra 22 spray before styling are important. Violet tones generally fade fairly well, so these tones aren’t required as much upkeep as others but prepare to be back in the salon in 6-8 weeks for a retouch.

#29: Deep Blue Sea Mermaid Hair Color

This deep blue sea mermaid’s hair is bright and bold! It’s got a deep purple root blending down into a beautiful and dimensional blend of topaz shades. A seamless blend was created as the color traveled down the strand! It’s a statement piece created by salon owner and stylist Laurie Percoco of Pennsylvania.

To achieve the color, Percoco states, “Find a stylist who has developed their technique with fashion shades to give a killer color melt. Mermaid hairstyles are popping with color. Mermaid’s hair is a huge trend that is here to stay!”

Percoco points out that a mermaid hairstyle also takes a lot of maintenance. At-home care is super important, so ladies must use a sulfate-free color care shampoo and conditioner.

#30: Light Clear Blue Mermaid Hues

These mermaid tresses resemble a clear blue sky with a couple of wispy clouds.

Made by Virginia-based hairstylist Carrie Withers, this color is very high-maintenance and can be damaging if you don’t go about it correctly.

Withers suggests going to the salon every 6 weeks. “That makes for an easy and safe regrowth application with a lightener. Don’t opt for this type of color for women with dark hair. Likewise, for women who want more pastel tones, stick with naturally blonde/light brown,” she states.

For women wanting something on the blue/green side of the spectrum, Withers warns that it’s a little more commitment because the underlying green tones can be pretty difficult to remove.

#31: Green and Blue Lagoon Mermaid Hair

This is a half-and-half color melt mermaid hair by licensed cosmetologist Karol Negron of Florida. For this masterpiece, the mermaid green hair color is the main attraction.

“You can see the different shades of blue and mint and then green. Ask your stylist to use Guy Tang MyDentity Mystic Blue, Arctic Blue, Mint of Steel, Pulp Riot, Absinthe, and Area 51 to achieve this color,” says Negron.

A color like this looks great on fair skin, but you can rock pretty much anything if you have a great personality!

“Things to remember when doing color like this is that you need to have a level 10 clean canvas,” Negron recommends. “Make sure to use a pH bonder to protect the hair from the damage of the lightning process. A good lightener to achieve a perfectly clean canvas is key to having great results,” she adds.

These colors take a long time to achieve, so be ready to spend the day with the hairstylist. Negron also points out that these colors are very expensive but worth trying.

#32: Pink, Purple, and Yellow Mermaid Hair

Try out a fun combo of pink, purple, and yellow mermaid hair for little pops of surprising contrast. Dark purple roots help blend regrowth and transition well into vibrant pink. Adding ribbons of warm colors like yellow or orange contrast against the cool pink and purple colors for exciting bursts of brightness in vivid hair.
