L'Oréal Paris Preference Permanent Hair Dye - Dark Brown

This permanent hair dye is formulated to provide fade-defying color and lustre for up to eight weeks, depending on hair type and care routine.

Yes, an allergy alert patch test must be performed 48 hours before *each* use, even if you have colored your hair before or with the same product. This is a critical safety measure.

No, the L'Oréal Paris Préférence Permanent Hair Dye is not intended for use on persons under the age of 16.

If dye gets on your skin, gently wipe it off immediately with a damp cloth. For stubborn stains, a small amount of petroleum jelly or a specialized dye remover can be used, following product instructions.

To maintain shine and prevent fading, use shampoos and conditioners specifically formulated for color-treated hair, rinse with cool water, and consider using a weekly hair mask for extra nourishment and gloss.

Always refer to the instruction leaflet for specific guidance regarding previously treated hair. Generally, wait a few weeks after chemical treatments like perms or relaxers before coloring. Bleached hair may absorb color differently, potentially resulting in a darker or more intense shade.

Ensure you strictly followed the application time. Over or under-processing can affect the final shade. For unevenness, verify hair was saturated thoroughly during application. Consult a professional stylist for correction if needed.

Immediately rinse hair and scalp thoroughly with water. If irritation persists or worsens, seek medical attention. Always perform an allergy patch test 48 hours prior to coloring to prevent severe reactions.

Ensure you used the provided conditioner after rinsing, as it's formulated to nourish. For ongoing dryness, incorporate deep conditioning treatments weekly and use color-safe, moisturizing hair care products. Avoid excessive heat styling.
