Lime Crime Unicorn Hair Dye Valentine (Crimson Red) — semi-permanent vegan full-coverage color

Valentine by Lime Crime is a semi-permanent, vegan crimson-red hair dye that delivers full-coverage, vibrant color for pre-lightened hair without peroxide or ammonia. Lime Crime Unicorn Hair in Valentine is a richly pigmented, DIY-friendly color formulated to give bold crimson results at home. Designed to deposit intense red on pre-lightened blonde shades and add a vivid tint to lighter browns, this semi-permanent dye balances fun, high-impact color with conditioning ingredients for improved shine and manageability. The scent is a sweet citrus-vanilla, and the formula avoids PPD, peroxide, and ammonia while remaining cruelty-free and vegan.

How will Valentine look on my current hair color?

Color payoff depends on your starting shade and whether your hair is pre-lightened. On platinum to medium blonde, Valentine achieves its truest crimson finish; on dark blonde or light brown it creates a noticeable red tint rather than full opacity. On darker bases, expect a subtler effect that may require pre-lightening for the brightest result.

• Platinum to medium blonde: vivid crimson payoff
• Dark blonde/light brown: tinted red hue, semi-sheer
• Dark brown/black: subtle stain unless pre-lightened first
• Always do a patch and strand test to preview color

How long does the color last and how should I maintain it?

Being semi-permanent, Valentine gradually fades with shampooing and exposure to sun and styling, with longevity influenced by hair porosity and care routine. Use sulfate-free shampoos, cool water rinses, and color-safe conditioners to extend vibrancy. Refresh with a color-depositing conditioner or a repeat application when the shade softens to your preferred intensity.

• Fades gradually—frequency depends on hair health and wash routine
• Use gentle, color-safe products and cool water for longer wear
• Conditioning treatments help maintain shine and reduce fading
• Reapply as desired to restore full saturation

Is this formula safe for home use and what should I know before applying?

Unicorn Hair is developed for at-home application but requires basic preparation to achieve even, vibrant results. Pre-lighten darker hair if you want maximum color intensity, and always perform both a patch test and a strand test to check for allergic reactions and final shade. Follow timing and sectioning guidance on the packaging for even coverage and rinse until water runs clear.

• DIY-friendly but best on pre-lightened hair for full effect
• Patch and strand testing recommended before full application
• Follow instructions carefully for timing and even saturation
• Rinse thoroughly and use color-safe aftercare products
