Lime Crime Unicorn Hair Dye Jello Tropical Green — Semi-Permanent Full-Coverage Vegan Color

Lime Crime Unicorn Hair Dye in Jello is a semi-permanent, vegan tropical green formula that delivers vivid, full-coverage color to pre-lightened hair with a sweet citrus-vanilla scent.

Designed for at-home creativity, Lime Crime Unicorn Hair transforms pre-lightened or light base shades into striking fantasy colors without ammonia, peroxide, or PPD. The Jello shade gives a bright, tropical green tone with conditioning ingredients to help maintain softness and shine. Because it’s ultra-pigmented, results vary by starting color and hair condition, so patch and strand tests are recommended before applying to the whole head.

How vibrant will Jello look on my hair?

Jello deposits super-saturated green pigment most effectively on pre-lightened platinum to medium blonde hair, producing a bold tropical shade. On darker bases it will add a tint or muted green reflection rather than full opacity. Expect intensity to fade gradually with washing and exposure to sunlight; longevity depends on hair porosity, base color, and hair care routine.

• Best on pre-lightened platinum to medium blonde for full vibrancy
• Light brown or dark blonde gets a tinted green effect
• Not designed to lift natural color — pre-lightening may be required
• Color fades with shampoos and UV exposure; use color-safe products

Is this dye gentle on hair and cruelty-free?

Lime Crime Unicorn Hair is formulated without harsh chemicals like ammonia, peroxide, and PPD, and includes conditioning fatty acids and vitamins to help maintain moisture and shine. The brand is certified cruelty-free by Leaping Bunny and PETA, and the formula is vegan. While the dye is designed to be less damaging than permanent oxidation dyes, pre-lightening processes can still stress hair.

• Free from ammonia, peroxide, and PPD
• Contains conditioning agents for added softness and luster
• Leaping Bunny and PETA certified cruelty-free; vegan formula
• Pre-lightening may still be necessary — follow care guidance

How do I use Jello for best results and how long does it last?

Apply to clean, dry, pre-lightened hair for the most even and vibrant coverage. Leave the product on according to the brand’s instructions, rinse with cool water, and use sulfate-free, color-safe shampoo and conditioner to extend wear. The dye is semi-permanent; typical wear ranges from several washes to a few weeks depending on hair type and maintenance.

• Perform a patch and strand test before full application
• Apply to pre-lightened hair for brightest results
• Rinse with cool water and use color-safe haircare to prolong vibrancy
• Expect fade over time—refresh color as needed

What should I know before attempting a DIY color change?

Plan the process: assess your base shade, gather protective gloves and tools, and read instructions fully. If you’ve previously chemically treated or damaged hair, consider a professional consultation or perform a small strand test. Keep in mind scent notes—Jello features a sugary citrus-vanilla aroma during application—and always follow safety recommendations for skin sensitivity.

• Do a patch and strand test to check color and sensitivity
• Use gloves, barrier cream, and proper application tools
• Consider professional help for heavy color corrections or fragile hair
• Be prepared to maintain color with gentle, color-safe routines

Who is this for: Lime Crime Unicorn Hair Dye in Jello is ideal for creative self-expressers, cosplayers, and anyone who wants a vivid tropical green without permanent oxidation chemistry. It’s best suited for people willing to pre-lighten their hair or those with naturally light bases seeking bold, playful color. If you value vegan, cruelty-free beauty and enjoy changing hues frequently, Jello gives a high-impact option for at-home fantasy coloring.
