L'Oreal Paris Excellence Creme Permanent Hair Dye - 6U Universal Dark Blonde

Yes, L'Oreal Paris Excellence Creme is a permanent hair dye, meaning the color change is long-lasting and grows out with your hair's natural growth.

Absolutely. A patch test is mandatory and must be performed 48 hours before each application to check for potential allergic reactions. Even if you've used hair dye before, sensitivities can develop.

While the formula is ammonia-free and contains caring agents, a patch test is crucial for anyone, especially those with sensitive skin. If you experience any reaction during the patch test, do not use the product.

Each pack includes 1x colouring cream, 1x developer cream, 1x shampoo (post-color), 1x conditioner (post-color), and 1x pair of protective gloves.

As a permanent hair dye, the color is designed to be long-lasting and will remain until your hair grows out or is recolored. Its vibrancy can be maintained with proper color-safe hair care products.

Generally, yes, but it's important to consult the specific instructions within the packaging, as they may contain special guidance or warnings for hair that has been previously colored, permed, or relaxed.

Ensure the product was applied to dry hair and left for the full recommended development time. Make sure enough product was used, especially on resistant grey areas. Re-read instructions for specific grey coverage tips.

This can happen if the dye was left on for too long or if your hair was previously very porous. Next time, consider reducing the development time slightly, or choose a lighter shade. Regular washing with clarifying shampoo might subtly lighten the color over time.

Rinse immediately with plenty of water. If discomfort persists, seek medical advice. This could indicate a sensitivity or allergic reaction, even if a patch test was performed. Discontinue use.

Ensure the coloring mixture was thoroughly shaken and applied evenly from roots to tips. For future applications, section your hair carefully to ensure complete coverage of all strands.
