Lime Crime Unicorn Hair Dye — Blue Smoke Semi-Permanent Steel-Blue Tint, Vegan Conditioning Formula

Lime Crime Blue Smoke Unicorn Hair is a semi-permanent, damage-minimizing steel-blue hair dye that deposits vivid color while conditioning hair. Lime Crime's Unicorn Hair in Blue Smoke offers a do-it-yourself semi-permanent tint that gives pre-lightened or lighter natural hair a cool steel-blue finish while leaving strands feeling soft. The formula is vegan, cruelty-free, and formulated without peroxide, ammonia, or PPD; it also contains conditioning fatty acids and vitamins to help maintain moisture and shine as color wears.

How will Blue Smoke look on my hair?

If your hair is platinum to medium blonde, Blue Smoke will deliver a saturated steel-blue tone with strong color payoff. On dark blonde to light brown hair it will register as a subtle blue-gray tint rather than fully opaque color. Results vary by starting shade and hair porosity, so expect deeper, truer color on lighter bases.

• Platinum/very light blonde: vibrant, steel-blue finish
• Medium blonde: noticeable blue-gray shade with good saturation
• Dark blonde/light brown: faint blue-gray tint, more subtle
• Unlifted dark hair: minimal visible change unless pre-lightened

Is this formula gentle on hair and scalp?

The Blue Smoke formula is designed to be damage-minimizing compared with permanent oxidative dyes because it’s semi-permanent and free of peroxide, ammonia, and PPD. Conditioning agents like fatty acids and vitamins are included to help moisturize and add shine during wear. Always follow directions and perform a patch and strand test to confirm compatibility with your hair and skin.

• No peroxide, ammonia, or PPD in the formula
• Enriched with fatty acids and vitamins for moisture and shine
• Vegan and Leaping Bunny/PETA certified cruelty-free brand
• Recommended patch and strand testing before full application

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

Semi-permanent shades fade gradually with shampooing and time; longevity depends on hair porosity, starting color, and washing habits. To extend vibrancy, wash with cool water, use sulfate-free or color-safe cleansers, and minimize frequent washing. Refresh with targeted color-depositing conditioners or repeat application as desired.

• Fades with each shampoo; frequency varies by hair and routine
• Cool-water washes and color-safe products preserve tone longer
• Touch-ups or color-depositing conditioners can refresh shade
• Avoid heavy heat styling to reduce premature fading

What should I do before applying Blue Smoke at home?

For best results, start with pre-lightened hair (platinum to medium blonde) to achieve the truest steel-blue shade. Conduct a patch and strand test to check for color outcome and skin sensitivity. Follow package instructions for timing, rinsing, and aftercare to preserve both hair condition and color payoff.

• Pre-lighten darker hair to recommended levels for full effect
• Perform patch and strand tests before full-head application
• Follow timing instructions precisely for desired intensity
• Rinse thoroughly and use conditioning treatments afterward
