Intelligent Green Dyes: Following advanced color wheel science, green is the direct complementary color that cancels out red. These highly targeted pigments micro-penetrate the hair shaft during the cleansing wash, counteracting the warm copper-red reflection that emerges as artificial brown dyes fade, ensuring your brunette shade stays perfectly cool and pure.

Color Spectrum Complex: A precisely calibrated formula that functions over chemically altered hair as a "smart pH-rebalancing lock and a scale-tightening shield". Chemical processing forces the hair cuticles to lift and remain open, making them highly vulnerable to moisture loss. This complex safely returns the fiber to its healthy acidic state, flattening the open cuticles firmly over the color matrix to lock color inside and maximize light reflectivity

Active Red Tone Neutralization: Utilizes specialized green pigments to counteract and eliminate unwanted red and orange undertones in brown hair.

5-Dimensional Color Lock: Seals the color spectrum tightly within the core to maintain high-definition vibrancy and prevent premature washing out.

Gentle & Purifying Cleanse: Thoroughly purifies the hair and scalp skin from hard water mineral buildup without stripping native hydration.

Anti-Frizz Cuticle Smoothing: Rebuilds surface manageability, leaving your long brunette strands fluid, bouncy, and exceptionally easy to detangle

During every standard wash cycle as the essential "Step 1" code to stabilize your artificial brunette tone and protect it from daily oxidation.

As soon as warm, brassy red highlights begin to alter your desired rich chocolate or dark brown hair dimensions.

Step 1: Wet your hair thoroughly with lukewarm water (avoid hot water as it damages printed color bonds and strips structural lipids).

Step 2: Dispense an adequate amount of the product and massage it gently into your scalp using your fingertips (never your nails) to stimulate localized blood flow, working the formula into a rich lather across your lengths and ends.

Step 3: Allow the foaming active dyes to process on the hair for up to one minute to optimize neutralization, rinse thoroughly with cool water, and follow with your regular L'Oréal professional conditioners or masks.
