Lime Crime Unicorn Full Coverage Hair Dye — Blue Smoke steel‑blue semi‑permanent, vegan conditioning paste

Lime Crime Unicorn Full Coverage Hair Dye in Blue Smoke is a semi‑permanent, vegan hair color that deposits a steel‑blue shade for vivid, salon‑style results at home.

This concentrated paste is designed to deliver saturated color to pre‑lightened hair and a subtle tint to darker bases, while avoiding peroxide, ammonia, and PPD. The formula includes conditioning ingredients to help preserve shine and manageability, and it carries Lime Crime’s signature sugary citrus vanilla scent to make application more pleasant. It’s ideal for DIY colorists who want bold, long‑lasting blue without permanent chemical processing.

How intense will Blue Smoke look on my hair?

The final result depends on your starting level: platinum or very light blonde produces the truest steel‑blue payoff; light brown or dark blonde will show as a muted blue tint. Color longevity varies with hair porosity, washing frequency, and styling choices, so brighter, longer wear generally requires lighter, healthier hair.

• Best payoff on pre‑lightened platinum to medium blonde hair.
• Light brown/dark blonde achieve a subtle blue overlay.
• Color fades gradually with washes—use color‑safe products to extend wear.
• Perform a strand and patch test to preview shade and compatibility.

What should I do before and after applying this semi‑permanent dye?

Prepare hair by ensuring it’s clean and pre‑lightened to the recommended level for optimal shade. After coloring, rinse with cool water until it runs clear and use a sulfate‑free, color‑safe shampoo and conditioner to protect tone. Regular deep conditioning helps maintain softness because bright dyes can highlight dryness in porous hair.

• Pre‑lighten to the recommended level for vivid results.
• Do a strand test to check color and timing before full application.
• Rinse with cool water and use color‑protecting haircare.
• Deep condition weekly to preserve texture and shine.

Is this product safe and ethical to use?

Lime Crime’s Unicorn Hair is formulated without ammonia, peroxide, and PPD and is certified cruelty‑free and vegan. While the dye avoids several harsh chemicals, always follow instructions and perform a patch test to check for sensitivities. The brand emphasizes ethically sourced ingredients and manufacturing practices across the line.

• Free from ammonia, peroxide, and PPD.
• Leaping Bunny and PETA certified cruelty‑free and vegan.
• Manufactured with globally sourced ingredients and quality controls.
• Patch testing recommended for allergy avoidance.

How can I maintain Blue Smoke between touch‑ups?

Minimize washing frequency and choose cool water to slow color loss. Use a sulfate‑free, pigmented shampoo or color‑deposits to refresh tone, and protect hair from prolonged sun exposure and heat styling to preserve vibrancy. When fading occurs, reapply a small amount to roots or use targeted color‑refresh products rather than full reprocessing.

• Wash less frequently and with cool water.
• Use sulfate‑free, color‑safe shampoos and conditioners.
• Apply color‑deposits or toners to refresh shade between full applications.
• Limit heat styling and use UV protection to maintain color.

Who is this for: Lime Crime Unicorn Full Coverage Hair Dye in Blue Smoke suits creative DIY hairstylists who want a bold steel‑blue color without permanent chemical processing. It’s best for people who can pre‑lighten hair to the recommended level or accept a toned tint on darker bases, and who are willing to follow at‑home care routines to prolong vibrancy and hair health.
