GARNIER NUTRISSE Ultra Color - Infinite Black

While Garnier Nutrisse Ultra Color is an ammonia-free formula, which can be gentler, it is crucial to perform an allergy patch test 48 hours before each application to ensure compatibility with your skin.

As a permanent dye, it's generally recommended to color your full head every 6-8 weeks. For root touch-ups, you can reapply as needed, typically every 4-6 weeks, focusing only on the new growth.

Infinite Black provides a deep, intense black shade. While it's a strong, rich color, it's designed to look vibrant. The final appearance can vary slightly based on your natural hair color and porosity.

Immediately wipe any dye off your skin with a damp cloth. For stubborn stains, a small amount of non-gel toothpaste or specialized hair dye remover can be used, then rinse thoroughly. Always wear gloves during application.

Yes, but be aware that previously bleached or very light hair may absorb black dye more intensely or appear flatter. It's always advisable to perform a strand test on a small, inconspicuous section of bleached hair first to preview the result.

Garnier Nutrisse Ultra Color is formulated to offer up to 100% grey coverage. For best results on resistant grey hair, ensure thorough application and adherence to the recommended development time.

Ammonia-free formulas like this one typically have a less pungent odor during application, making the coloring experience more pleasant. They are often perceived as being gentler on the hair, contributing to less dryness and damage.

Ensure the dye was applied evenly and left on for the full recommended development time. Hair porosity can affect uptake; very porous hair might absorb color differently.

Make sure sufficient product was applied to grey areas, as they can be more resistant. Consider extending the development time slightly (but never beyond the maximum stated in instructions) if grey coverage is a persistent issue.

Rinse immediately if discomfort is severe. Always perform a patch test 48 hours before use to check for allergic reactions. If irritation persists, consult a doctor.

Thoroughly use the nourishing conditioner provided after rinsing the dye. Continue with a good quality, hydrating conditioner and hair mask in your routine. Ensure you did not exceed the development time.

Review your hair care routine. Use color-safe products, wash with cooler water, limit heat styling, and protect hair from sun exposure. Over-washing can also contribute to faster fading.

Ensure hair was sectioned properly and the dye was distributed thoroughly and evenly from roots to ends. For long or thick hair, it's sometimes helpful to have assistance or use two kits.
