32 Gorgeous Mermaid Hair Color Ideas You’ll Love in 2025

Mermaid hair is a popular trend where two or more bright or pastel colors blend into long, wavy hair. It combines long, flowing waves with lots of bold, magical colors. Colorful hair dye is quickly becoming a favorite choice for many. Mixing different pastel and vivid shades makes this style exciting and fun, and it will definitely get you noticed.

From tight, tiny curls to soft, large waves, these styles help show off many fashion colors. The hair length also helps blend colors smoothly and change how bright or deep they look.

Beautiful hair requires careful attention. You may need to bleach your hair several times and be patient to get the colors you want. After coloring, use protective hair products and visit the salon sometimes to keep your hair looking its best.

Before you book your next hair appointment, explore these trendy mermaid hair color ideas for inspiration.

#1: Perfect Mermaid Hair Highlights

This stunning mermaid hair color combines red, violet, and brown highlights. It will make you feel like a true ocean goddess. If you want a bold and striking style, this is perfect for you. To get this look, ask your stylist for a rich brunette base with red violet highlights. This mix will create a vibrant and unique color. Use a deep conditioner once a week to keep your hair healthy and soft. Finish with a shine spray like Unite 7SECONDS Glossing Spray. It will help lock in moisture and add a beautiful shine.

#2: Long Blue Pixie with Green Fringe and Edges

This pixie haircut has a blue color, green bangs, and choppy edges. It’s a bold style that helps you show off your personality. A pixie with a mullet shape is easy to care for and lets you express yourself. If you want your pixie to match your natural hair texture, try a gentle razor cut. The razor adds texture and gives your hair a relaxed, natural look.

#3: Vivid Blue-Pink-Purple Mermaid Locks

These mermaid locks shine with bright blue, pink, and purple colors. To get mermaid hair, you can try many methods, and using bold colors is a popular choice. First, lighten your hair to a fresh, level-9 blonde all over. Once you reach this light shade, you can mix and match many color options. Shades of aqua, blue, green, purple, and pink blend together to give a magical mermaid look.

#4: Wavy Mermaid Hair with a Barrette

This barrette gives a unique style to wavy mermaid hair. Using clips made from different materials can change your whole look. Waves in your hair bring out its lovely colors. For extra shine, try using a shine spray.

#5: Mermaid Barbie Hair

If you want your wavy hair to stand out, try a bright, mermaid Barbie-inspired color. This stunning style mixes cool and bold shades that look like ocean colors. To get this look, ask your stylist to blend deep sea blues, greens, and shiny pinks and purples with your natural hair. While mermaid colors work well with warm skin tones, they can also look great on lighter skin by using pastel variations. To keep your color vibrant, avoid shampoos and conditioners with sulfates, as they can make the color fade faster.

Try out this blue hair with soft mermaid waves! Use a deep waver iron to create these waves easily. Look for hairstylists who are experts in fashion colors.

Coral pink shades make a stylish mermaid hair color. Try this look with long hair and gentle waves to start the trend.

#8: Sapphire Teal Waves

Sapphire teal waves make a bold statement. They look stunning but need extra care. With any fashion hair color, expect to visit your stylist more often. Fashion colors do not last long. They fade quickly, especially if you do not follow all the care tips. To help your color last, wash your hair with cold water, wash it less often, use lower heat on styling tools, wait at least 48 hours before washing after coloring, and ask your stylist which shampoo and conditioner to use.

#9: Gray to Teal Blue Ombre

Give yourself a stunning ombre style by blending dark gray into teal blue. A hair colorist or stylist can help you get this beautiful look easily. To keep your color bright, use products made for colored hair like Matrix Color Me Vivid. Wash your hair with cool water instead of hot to protect the color. For extra care, try Redken’s new acidic bonding concentrate, which includes shampoo, conditioner, and a leave-in treatment. It repairs damage and adds moisture, helping your hair stay bright and healthy. Your mermaid-inspired ombre will catch everyone’s eye and make a bold statement wherever you go.

#10: Ocean Blue

This stunning ocean blue shade lets you blend with the sea. It’s a bold, trendy color that helps you stand out. Bright mermaid hues tend to fade fast, so you’ll need regular salon touch-ups.

#11: Fishtail Braid on Mermaid Hair

Return to your best self with this perfect Merpeople hairstyle. Bright fuschia and magenta hues blend together in a fishtail braid, giving you a true ocean-inspired look. Add loose beach waves to your long mermaid hair for more depth and a bold, eye-catching style.

#12: Long Mermaid Hair

Long mermaid hair combines teal, purple, and blue shades. It works well if your natural hair is dark and lightens only to an orange-yellow tone. Teal, dark purple, and deep blue colors look great on this base. Start with green-teal roots, then blend in purple and blue streaks. This mix creates a stunning mermaid-inspired look.

#13: Pastel Mermaid Hair

Pastel mermaid hair combines soft baby blue with darker blue streaks, light violet, and creamy green shades. To get this pastel mermaid look, your hair must be bleached to a pale yellow base. Begin with a deeper hue of pastel blue at the roots. Then blend it into a lighter baby blue, followed by pastel green, purple, and blue streaks.

#14: Short Mermaid Hair

Short mermaid hair is a shoulder-length style that mixes blue, teal, green, and purple colors. The roots are dyed a dark blue or deep teal. Bright green highlights stand out throughout the hair. Purple and rich blue strands are added, then styled with large barrel curls. This shows off the beautiful mix of colors in the mermaid look.

#15: Mermaid Curls

#25: Bold Blue and Purple Mermaid Hair

This mermaid hair color blends a purple sunset shade with a stunning blue ocean tone. The best part is you can mix different base pigments to create the exact color you want.

My top advice for women wanting this hair color is to have a thorough talk with your stylist. Discuss your clothes, if you wear makeup, and how you usually style your hair. Also, knowing your face shape helps your stylist plan the color placement. This way, the contrast will look great when you see it at eye level.

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

This mermaid hairstyle shows off many colors. It has bright pink, purple, green, and blue shades, with rainbow colors at the tips.

“I chose the hair colors based on a beta fish,” says hair colorist Tori Briggs from Rocky Mount, NC. “The main shades are dark blue, light blue, and mint green. I also added touches of pink, purple, and neon green underneath and around the face,” she explains.

A color melt aims to create smooth movement in the hair. It starts with a soft, calming look at the roots and then blends into bright, bold colors. The dark blue shadow root makes the transition look natural as the hair grows or fades over time.

If you want rainbow mermaid hair, Briggs suggests thinking about your personality and skin tone. “If you are more quiet, pick soft pastel shades for a relaxed look. If you are outgoing, choose bright, bold colors instead.”

#27: Sea Foam Green Mermaid Short Hair

This sea foam green mermaid look, created by Florida stylist and salon owner Rachel Ringwood, blends elegance with a punk vibe. Switching from a high-maintenance bleach and tone to magenta adds a bold, multi-toned style that’s easier to maintain.

“Choosing quality products can make a big difference for your mermaid hair dreams! Ringwood advises using products that are free of sulfates, parabens, and sodium chloride. Pick styling products with less alcohol, and avoid too much heat, since it can cause your color to fade quickly.”

Bright colors are making a big impact, and more women are opening up to new opportunities in many fields. Art, color, and self-expression work perfectly together, so why not celebrate them in every way?

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

This blue-purple mermaid hair has silver highlights in the middle. The lighter shade creates a layered ombré effect. Darker roots and ends help the middle section stand out even more!

“Bright or trendy hair colors require dedication,” explains hair colorist Courtney Alexander from Lebanon, MO.

Use hot tools on a low heat setting and apply a quality heat protectant like Kenra 22 spray before styling. Violet shades usually fade nicely, so they need less maintenance than other colors. Still, plan to visit the salon every 6-8 weeks for a touch-up.

#29: Deep Blue Sea Mermaid Hair Color

This mermaid-inspired hair features a bright, bold deep blue color. The roots start with a rich purple that smoothly fades into stunning topaz shades. The colors blend perfectly along each strand. Salon owner and stylist Laurie Percoco from Pennsylvania created this eye-catching look.

According to Percoco, “Look for a stylist skilled in fashion colors to create an amazing color blend. Mermaid hairstyles are full of bright colors. This popular trend is here to stay!”

Percoco explains that a mermaid hairstyle needs a lot of upkeep. Women should use a sulfate-free shampoo and conditioner made for colored hair to care for it at home.

#30: Light Clear Blue Mermaid Hues

This mermaid hairstyle looks like a bright blue sky with a few soft, white clouds.

This hair color was created by Virginia hairstylist Carrie Withers. It needs a lot of care and can harm your hair if not done properly.

Withers recommends visiting the salon every 6 weeks. “This timing allows for a simple and safe regrowth touch-up with lightener. Avoid this color style if you have dark hair. Also, if you prefer pastel shades, it’s best to start with naturally blonde or light brown hair,” she explains.

Withers explains that if women want blue or green shades, they should know it takes more effort. The green tones underneath are hard to get rid of.

#31: Green and Blue Lagoon Mermaid Hair

This half-and-half color melt mermaid hairstyle was created by licensed cosmetologist Karol Negron from Florida. The highlight of this look is the stunning mermaid green hair color.

“Notice the mix of blue, mint, and green shades. To get this look, ask your stylist to use Guy Tang MyDentity Mystic Blue, Arctic Blue, Mint of Steel, along with Pulp Riot Absinthe and Area 51,” says Negron.

This color looks amazing on fair skin. But with a confident personality, you can pull off any color you like!

“When coloring hair like this, start with a clean, level 10 base,” Negron suggests. “Use a pH bonder to shield the hair from damage during lightening. Choosing a quality lightener helps you get a perfect, clean base for the best results,” she adds.

These colors require many hours to create, so plan to stay at the salon all day. Negron also mentions that while these colors cost a lot, they are definitely worth trying.

#32: Pink, Purple, and Yellow Mermaid Hair

Experiment with a playful mix of pink, purple, and yellow mermaid hair for eye-catching pops of color. Deep purple roots hide new growth and smoothly fade into bright pink. Adding streaks of warm shades like yellow or orange creates bold, lively highlights that stand out against the cool pink and purple tones.
