L'OREAL TECHNIQUE HiColor Violet & Blacks Permanent Hair Color, Black Onyx — 30‑Minute Lift, Anti‑Brass Ceramide R

L'Oréal Technique HiColor Violet & Blacks Permanent Hair Color lifts dark hair up to 3–4 levels and deposits long-lasting Black Onyx shade without brassiness in a single, 30-minute step.

Formulated for naturally dark bases—from black to medium brown—this professional-strength permanent color combines lifting power and targeted toning to neutralize warm, orange undertones while delivering an intense, true-to-shade result. The creamy formula penetrates the hair fiber to condition as it colors, offering a fast processing time and resilient pigments designed to resist fading. No separate pre-lightening stage is required, making it a convenient option for transforming darker hair into vivid violet-black and deep onyx tones.

How does HiColor lift dark hair without pre-lightening?

The HiColor system uses a multi-lift developer and pigment complex engineered to raise pigment levels in darker hair and simultaneously deposit corrective tone. This two-fold action neutralizes unwanted warmth while building the chosen shade so you see visible lift and color in one application. Expect even, consistent lift on natural black to medium-brown bases when applied according to instructions.

• Multi-lift formula lifts hair 3–4 levels in one step
• Integrated toners counteract orange and brassy undertones
• Creamy consistency ensures even coverage and penetration
• 30-minute processing time for quick results

Will this product damage my hair or cause breakage?

This permanent color includes a ceramide R complex intended to condition the hair during coloring, helping protect the fiber. While permanent coloring alters hair structure, the formulation aims to reduce brittleness and breakage risk compared with harsher lightening methods. Using recommended aftercare and not overlapping repeated applications ensures better integrity over time.

• Ceramide R complex for conditioning during processing
• Rich crème texture minimizes friction and tangling
• Recommended professional technique limits over-processing
• Follow-up treatments and color-safe care improve resilience

How long does the color last and how true is the shade?

The formula is designed to be permanent with pigments that resist fading, delivering vivid, long-lasting color when cared for properly. Results are true-to-shade on dark bases thanks to the combined lift-and-tone action, but longevity depends on hair porosity, shampooing frequency and sun exposure. Use sulfate-free shampoos and UV-protective products to extend vibrancy.

• Permanent pigments formulated for fade resistance
• True-to-shade outcomes on dark hair with proper application
• Avoiding harsh shampoos and sun exposure preserves color
• Touch-ups may be needed as new growth appears

What are the practical steps for at-home or salon use?

Mix the color cream with the recommended developer, apply evenly to dry, unwashed hair, and process for about 30 minutes. Rinse thoroughly until water runs clear and follow with appropriate conditioning and color-care products. Always perform a patch and strand test before full application to check compatibility and final tone.

• Mix and apply to dry, unwashed hair following instructions
• Process for approximately 30 minutes for full lift and deposit
• Rinse and condition; use color-care products to maintain results
• Patch and strand tests recommended before full use
