Features

  • Sea Witch Unicorn Hair Dye: Dyed and gone to Unicorn Heaven! Lime Crime Unicorn Hair is a DIY-friendly, semi-permanent color dye that transforms hair into vibrant colors... all from the comfort of your own home. Sea Witch is a radiant rich teal that will make your fantasy hair color dreams come true, and its sugary citrus vanilla scent will make your transformation even sweeter!
  • Why You Need It: Not only does our damage-free, vegan hair dye give you fun, vibrant color, but this formula also contains conditioning ingredients like fatty acids and vitamins that help to moisturize your hair and boost shine.
  • Before You Use It: Unicorn Hair deposits super-saturated, vibrant color to pre-lightened platinum to medium blonde hair and adds a tint of color to dark blonde and light brown hair. The life cycle of the color depends on the shade and condition of your hair and how often you wash it. Always do a patch and strand test before coloring your full head because results may vary.
  • Benefits: This formula is free of harsh chemicals like PPD, Peroxide and Ammonia. Lime Crime is certified by both Leaping Bunny and PETA, and we design, manufacture, and assemble quality products using globally sourced ingredients for high performance wear and strong color pay-off.
  • Never Blend In: Lime Crime is a Vegan & Cruelty-Free makeup and hair brand that aims to inspire and invites self-expression. Through our vibrant color products, we encourage all to explore their individuality, embrace their uniqueness and always stand out from the crowd. Find joy through color and re-imagine your boundaries with Lime Crime.

Description

How long does semi-permanent hair dye last? Ideally, your color should last several weeks, but results may vary based on your hair health, how pigmented your dye is, how often you wash your hair, and your lifestyle and hair styling habits. What do you mean by Full Coverage? Our full-coverage hair dyes are our most pigmented, super-saturated formulas and are designed to gradually fade over the course of several weeks. Do I need to bleach before using this hair dye? Our damage-free hair dyes are formulated without bleach or chemical lighteners, so they won’t lighten your hair. As such, you’ll notice the best color payoff when you start with light hair. What colors are best for darker hair? Some of our most pigmented shades include Chocolate Cherry, Sea Witch, Mystic, Valentine, Flaming Red, and Anime. When used on dark hair, these dyes deposit a cute, subtle tint of color. How much Unicorn Hair Dye will I need? We suggest 1 jar for short, bob-length hair, 2-3 jars for hair reaching between the shoulders and waist, and at least 3 jars for hair that reaches beyond the tailbone.

  • Just What I Needed!
Color: Sea Witch (Rich Teal)
I was pleasantly surprised with the quality, smell, color match, and just how well this worked for my hair. It does stain whatever it touches, but I was able to clean out the shower and a few spots on my sink, so no harm done. I need to reapply the color after putting it on for the first time back in October, so it has lasted quite well for me! ... show more

  • Very pretty but it might last forever
Color: Sea Witch (Rich Teal)
Been using this hair dye for 5 years now, unfortunately out of stock on website so I ordered it here and had just as good experience. This will low-key stain your hair but I've been doing the same colour and don't plan on changing it so I prefer that way, lasts a good 3 months before fading, covers medium//chocolate brown hair without bleach but comes out brighter if you add highlights or something before. Smells super good too ... show more

  • Works great looks even better
Color: Sea Witch (Rich Teal)
I would definitely recommend this dye for people willing to dye their hair to a white blonde. I was able to oversaturate my waist length hair with two of these. Most other fashion colors would have taken so much more product. It also came off my skin very easily. I am overall very happy with the color and end condition of my hair. ... show more

  • The perfect green!!
Color: Sea Witch (Rich Teal)
I’ve been trying to find a green colored dye that is more green than blue once you use it. I absolutely love Lunar Tides dyes, but my green would always come out more blue and fade down to a very obvious blue. This dye though!! It’s perfect! It’s the exact green I was looking for and I love it! It smells great, was easy to apply, and didn’t dye my skin afterwards. It would run in the shower when I would wash my hair, but it never transferred to my clothes or pillows. It also lasts a long time! This picture is after a month from when I first dyed it, no touch ups! My hair is dark brown, so I did have it lightened before applying the color. This is now my go to color and brand! ... show more

  • Worth every penny!
Color: Sea Witch (Rich Teal)
The color is stunning! We tried a similar color with manic panic and it turned yellow green immediately. This brand, formula, and color are an easy 10/10!

  • my go-to green :)
Color: Sea Witch (Rich Teal)
i'm OBSESSED with sea witch, everybody knows me as the person who loves/is always wearing dark green. i have medium brown hair and hate bleaching it, mostly because it takes forever but also because i have waves/curls and i dont want to damage them. this stuff comes out BEAUTIFULLY every single time without fail, i leave it on for a few hours until it dries (at least 3hrs if not more) because i want it to be vibrant, but also since i don't bleach it, if i dont it comes out as a bit of a brassy/yellow gross color rather than a deep rich teal-green. it's demipermanent, so it won't affect your hair health if you leave it on long either :) it also stays vibrant even after several washes and turns out looking ombre (see pics). this stuff DOES stain, especially fingernails so definitely wear gloves when washing/rinsing and be conscious of running hands through hair, but it comes off of skin pretty easily with normal hand soap and with bleach for my plastic tub (the water also has washed it away over time). the color is so stunning though that with these being my only complaints i don't even really mind ... show more

  • Wow!!
Color: Sea Witch (Rich Teal)
This color is insaaaane! My daughter’s hair is dark brown and the vividness of the blue is beautiful even on her dark hair!! The purple is on the other side and even though it’s not as prominent it’s still pretty purple!! And it smells amaaaaazing!

  • Super long lasting! Takes forever to wash out
Color: Sea Witch (Rich Teal)
This product is pretty good. Want to start by saying that if you are looking for a cute couple weeks change, DO NOT get this! I have had it in for about 2.5 months and it is still there a little. I have had to use clarifying shampoo with backing soda to fade it. That being said, it’s super long lasting! It is super easy to use, an it really doesn’t smell bad (even though it should be expected to as it is color, y’all need to understand that color smells terrible normally). If you have light brown hair DO NOT leave it on more than 45 min. I left a section for 30 and it looked good, I did my whole head for an hour and it looked black....... but it does work on medium brown hair as that is what I have. ... show more
