How To Get Mermaid Hair At Home

You Will Need

  • A bleaching kit (if you have dark hair.)
  • Hair dye
  • Applicator brush
  • An old shirt
  • Color protecting shampoo and conditioner
  • Clips for sectioning
  • Hairbrush/comb
  • Gloves
  • Petroleum jelly
  • Plastic bowls


  1. Ensure that your hair has not been washed in 2-3 days. The oils in your hair will help with the lightening process.
  2. Brush out your hair to get rid of any tangles or knots.
  3. Wear your gloves and apply the petroleum jelly along your hairline on your forehead, neck, and ears.
  4. Following the instructions on the kit, mix your bleach.
  5. Section away the crown part of your hair and as per the instructions on the kit, apply the bleach onto the loose hair with the applicator brush.
  6. Once you’re done with the bottom sections, undo the sectioned away the top part of your hair and repeat the application process.
  7. Leave the bleach on for the recommended duration of time and then proceed to shampoo and condition your hair.

Note: You might have to repeat this process a couple of times to achieve the desired lightness.


  1. Once you’ve pre-lightened your hair, pick some mermaid colors of your choice.
  2. Ensure that your hair has been freshly washed and conditioned.
  3. Brush out your hair to get rid of any tangles or knots.
  4. Wear your gloves and apply the petroleum jelly along your hairline on your forehead, neck, and ears.
  5. Pour the hair dye into bowls. Have a separate bowl for each color if you are using more than one. For an ombre effect, take two bowls; one containing hair dye, and another containing hair dye that has been diluted with conditioner. (Arctic fox, manic panic, pravana, pulp riot, and crazy color are some good brands to work with.)
  6. Start applying the dye onto your lightened hair in sections. You can paint random strands with different colors, or you can use one or multiple colors to create an ombre effect.
  7. Once you’ve applied the dye, wait for 30 minutes.
  8. Wash your hair with a color protecting shampoo and conditioner.

Getting mermaid hair done at home is just one part of the equation. Maintaining it is the other part that is more important, and one that requires extra attention. Follow the mermaid hair care tips below to ensure the color stays on for a long time.

How To Take Care Of Mermaid Hair

  • Wash Gently: Use a sulfate-free, color-protecting moisturizing shampoo and conditioner 2-3 times a week to prevent color-fading and dehydration.
  • Rinse With Cold Water: Hot water can strip away the color and natural oils. So, use cold water to rinse your hair.
  • Avoid Overstyling: Minimize the use of heat-styling tools to prevent breakage.
  • Use UV Protection: Apply a UV-protectant spray or wear a hat when you are in the sun to protect your hair from color-fading.
  • Get Color Touch-Ups: Go for a color touch-up to maintain vibrancy every 3-4 weeks or as required.

Ariel is definitely our favorite Disney princess, and this is the perfect fantasy hair color, and we can say with conviction that this has to be Ariel because nobody else has red locks this gorgeous. This single-toned beachy curls mermaid style has been styled to perfection. The color has taken to the hair so evenly, it almost looks fake. In the best way possible, of course.

Via, a blogger, always loved The Little Mermaid. She writes, “I mean she had red hair, purple bra, and a green fishtail. The colors are popping and shouting everywhere, but she still looks exceptionally gorgeous and put-together (i).” Taking inspiration, Via decided to dye her hair an equally striking rose gold at a salon. Afterwards, she observes, “My friends loved it; my dad said I looked like my fancy Lola, whom I call Mommy 2, and my fiancé John thinks I look like an anime character (in a good way) of course.”

22. Pastel Mermaid Undercut

24. Clear Waters

What’s more breath-taking than relaxing in crystal clear waters? This hairstyle. The style starts off with aqua roots that soon melt to a gorgeous platinum. The mid-lengths start to take on a gorgeous ash-blue color near the ends. It is so easy to go wrong with adding movement at the mid-lengths, but this style is all things right.

25. Subtle Fishtail

Frequently Asked Questions

How much does mermaid hair coloring cost?

Danielle Keasling, a celebrity hairstylist, says, “Mermaid hair can cost anywhere from $100 all the way up to $1000 on average in salons, depending on the process. In order to lay in these fantasy tones, you need to pre-lighten the hair most of the time. This is a separate process that needs to happen in order to get the vibrancy of the fashion tones. However, if you’re naturally blonde, most of the time, pre lightening won’t be needed.”

What color is the mermaid blue?

Keasling says, “Mermaid blue is a combination of aqua, teal, retro blue, royal, and navy with reflections of silvers, grays, and greens.”

How do you do mermaid hair for short hair?

Use a flat iron to get the classic beach waves according to your preference. Finish your mermaid’s hair look with a glossy hairspray.

Are mermaid waves still in style?

Yes. Mermaid waves are a type of well-defined crimped hairstyle that is perfect for a beach day to accentuate your tresses.

Key Takeaways

  • Hair dye works best on hair that is not washed for 2-3 days as the oils in the hair help with the lightening process.
  • Wait for at least half an hour after coloring your hair and follow up with color-protecting shampoo and conditioner.
  • Hairstyles such as grey mermaid or aquamarine hair color may look good on wavy hair.
  • If you like braids, then try hairstyles such as mermaid fairy floss, or subtle fishtail.
