Garnier Nutrisse Permanent Hair Dye - 1 Black

As a permanent hair dye, the color is designed to last until your hair grows out or is re-colored. The vibrancy will remain for several weeks, but root regrowth will become visible, typically requiring a touch-up every 4-6 weeks.

Yes, Garnier Nutrisse Permanent Hair Dye is formulated to provide 100% gray coverage, delivering a rich, uniform black shade to blend away grays effectively.

Yes, it is crucial to perform a skin allergy patch test 48 hours before *each and every* application, even if you have used hair dye products before. Allergies can develop suddenly.

You can use this dye on previously colored hair. However, if your current color is significantly lighter or a very different tone, the results may vary. It's always best to perform a strand test on a small, hidden section of hair first to see the outcome.

Rinse eyes immediately and thoroughly with plenty of water for several minutes. If irritation persists, seek medical attention. Always read the safety warnings on the product packaging.

While permanent dyes can be harsh, Garnier Nutrisse is formulated with a restoring conditioner enriched with 5 oils, aiming to make hair 5x stronger and 2x shinier. Following the instructions carefully and using good post-coloring hair care can help minimize potential damage.

Yes, while often marketed to females, permanent hair dye can be used by anyone seeking to color their hair black, provided they perform the necessary patch test and follow all application instructions.

Ensure you followed the application instructions precisely, including development time and even distribution. If hair was very porous or previously colored unevenly, results can vary. A re-application on uneven areas or a slightly longer development (without exceeding the maximum time specified in the leaflet) might be considered after a few weeks, always with a new patch test.

This could indicate sensitivity. If you performed a patch test and had no reaction, ensure you didn't leave the dye on for too long or apply it too vigorously. Rinse immediately if irritation is severe. If it persists, consult a medical professional. Always perform a patch test 48 hours prior to each application.

This can happen if hair was already dry or porous. Ensure you used the provided restoring conditioner thoroughly. Incorporate a deep conditioning treatment or hair mask into your weekly routine, and consider using leave-in conditioners or hair oils to boost moisture and repair.

Harsh shampoos, hot water, excessive heat styling, and sun exposure can all contribute to fading. Switch to color-safe, sulfate-free hair products, rinse with cooler water, use heat protectants, and minimize sun exposure. Regular use of the nourishing conditioner can also help seal the cuticle and lock in color.

To prevent this, apply petroleum jelly to the hairline and wear old clothes/towels during application. For fresh stains on skin, a damp cloth with a mild soap or a specialized hair dye remover wipe may help. For surface stains, consult appropriate cleaning methods for the material affected.
