Garnier Nutrisse Blondelift UL1 Chestnut Blonde - Brown

This product is specifically designed for natural, untreated dark hair. Using it on previously colored or chemically treated hair may lead to unpredictable results, including uneven color or different lift levels than intended. It's best to consult a professional if your hair is not virgin.

Garnier Nutrisse Blondelift ul1 is a permanent hair dye, meaning the color will not wash out. It will gradually grow out with your hair. The vibrancy can be maintained with proper color-safe hair care and occasional toning if brassiness appears.

High Lift Technology refers to a specialized formulation that uses a higher concentration of peroxide combined with specific dyes to penetrate the hair shaft more effectively and lift natural pigments. This process lightens the hair up to 4 levels without requiring a separate bleaching step, especially on natural dark hair, while the dyes simultaneously deposit the new color.

The Deep Blue Anti-Brass Conditioner contains ultra-potent neutralizing pigments (blue/violet) that counteract unwanted warm undertones, such as orange or yellow, that can appear when lightening dark hair. It helps achieve a cooler, more luminous blonde result and leaves hair smooth.

Yes, a patch test is absolutely necessary and must be performed 48 hours before each application, even if you have colored your hair before. This test helps identify any potential allergic reactions to the dye ingredients, which can be severe.

While it is specifically formulated for natural, untreated dark hair, it will likely still lighten lighter hair, but the resulting shade and tone might be different from the intended Chestnut Blonde. For optimal results, use on natural dark hair.

Info needed: This product is primarily for lifting and coloring natural dark hair to a blonde shade. While permanent dyes generally cover grey hair, the primary function of this specific 'Blondelift' product is lightening, so its grey coverage capability might not be its strongest feature. Consult the product packaging or Garnier's official website for explicit grey coverage claims.

This product is specifically designed for natural, untreated dark hair. If your hair was previously colored or treated, results may vary. Ensure you applied the product evenly and left it on for the maximum recommended development time. Hair porosity can also affect lift; very resistant hair may require longer processing within limits.

Ensure you used the Deep Blue Anti-Brass Conditioner provided in the kit and left it on for the recommended duration. This conditioner contains neutralizing pigments to combat brassiness. If brassiness persists, consider incorporating a purple or blue toning shampoo/conditioner into your weekly hair care routine.

Uneven application is a common cause. Ensure the product is applied thoroughly and evenly from roots to ends. If coloring for the first time, apply to mid-lengths and ends first, then roots for the last portion of development time. For root touch-ups, apply precisely to new growth only before extending to ends if needed.

Stop application immediately and rinse thoroughly if severe irritation occurs. Always perform a patch test 48 hours before coloring to check for sensitivities. This product contains ingredients that can cause allergic reactions in certain individuals.

While this formula contains nourishing oils, permanent coloring can still be drying. Ensure you used the provided Deep Blue Anti-Brass Conditioner. Incorporate regular deep conditioning treatments, hair masks, and leave-in conditioners into your routine. Minimize heat styling and use heat protectants.
