They reveal the full shine of your hair fiber for vibrant gray and white hair.
Why use shampoos for gray and white hair?
Grey and white hair evolve over time. With the progressive loss of melanin, the hair fiber becomes more porous and more susceptible to dehydration, yellowing, and external aggressors. The GREY routine was developed to meet these specific needs. Enriched with hyaluronic acid to maintain hydration, copper peptides to support scalp vitality, and KeraScalp™ to strengthen the quality of the fiber, it supports grey and white hair on a daily basis. Our shampoo cleanses the fiber gently, while the purple shampoo helps neutralize yellow tones without drying out the lengths. Complemented by our conditioner and our leave-in day treatment, the GREY routine helps keep hair softer, brighter, and easier to style, day after day.
GREY SCIENCE
GRIS science is based on a simple conviction: grey and white hair are not a problem to be fixed, but a different fiber to be understood.
GRIS develops a comprehensive, biomimetic scientific approach to grey and white hair. By acting on the fiber and the scalp, our formulas lastingly preserve their quality, radiance, and vitality.
Provide lasting hydration
With the disappearance of melanin, gray and white hair becomes more porous and loses its ability to retain water. GRIS combines a very low molecular weight hyaluronic acid, which captures and maintains hydration, with Prodew® 500, a biomimetic complex of 11 amino acids inspired by the natural composition of hair, to restore moisture balance and strengthen the fiber.
Together, these active ingredients restore lasting hydration, which is essential for the quality of white hair.
Activate molecular biomimicry
GRIS relies on molecular biomimicry to draw inspiration from the natural mechanisms involved in hair vitality and structure.
The copper peptide, naturally present in the body, helps to preserve hair vitality over time, while Prodew® 500, a biomimetic complex of 11 amino acids inspired by the composition of the fiber, helps to strengthen its structure. This approach helps to lastingly preserve the quality of white hair, for a stronger, suppler, and shinier fiber.
Maintaining scalp balance
Yes, our formulas are designed for daily use, gentle on the scalp and hair fiber.

FAQ - ANTI-YELLOWING CARE
Why can gray and white hair turn yellow?
Deprived of melanin, gray and white hair is more sensitive to external aggressors. Pollution, limescale, ultraviolet rays, heat from styling tools, smoke, or certain product residues can gradually dull their color.
Yellow or golden tones may then appear. An anti-yellowing treatment helps to visually correct these unwanted tones in order to reveal a purer white and a more luminous gray.
Which GREY products help neutralize yellow undertones?
The GRIS anti-yellowing purple shampoo is the targeted treatment against yellow tones. Its purple pigments correct yellow and golden hues that can dull grey and white hair.
It is also integrated into several routines:
- The GRIS radiance duo combines the moisturizing care shampoo and the anti-yellowing purple shampoo.
- The GRIS softness & radiance trio adds the GRIS conditioner to nourish and facilitate detangling.
- The signature GRIS routine completes the ritual with the GRIS leave-in day care to prolong hydration and tame frizz.
Which GREY routine should I choose to fight against yellow undertones?
Choose the GRIS purple anti-yellowing shampoo on its own if you simply wish to add a corrective action to your usual routine.
The GRIS radiance duo is suitable when the priority is to cleanse, hydrate, and revive color. The GRIS softness & radiance trio is better suited if the hair is also dry, coarse, or difficult to detangle.
To address color, hydration, nourishment, and frizz, opt for the signature GRIS routine.
How do purple pigments neutralize yellow tones?
Their action is based on the principle of colorimetry. On the color wheel, violet is the complementary color to yellow.
The violet pigments temporarily settle on the surface of the hair fiber and visually neutralize yellow or golden tones. White hair appears purer, while gray hair regains more depth and luminosity.
What is the difference between purple shampoo and blue shampoo?
Purple shampoo primarily neutralizes yellow tones. It is particularly suitable for grey, white, or very light blonde hair.
Blue shampoo acts more on orange or brassy tones, often present in lightened brown hair. To remove yellow from grey and white hair, a purple shampoo is therefore generally more suitable.
Does GRIS purple shampoo color white hair?
No. The GRIS anti-yellowing purple shampoo is not a color-depositing shampoo. Its pigments temporarily correct the appearance of yellow tones without permanently altering the natural color of the hair.
On very light or particularly porous hair, leaving it on for too long may leave a slight, temporary purple tint. Follow the recommended processing time and rinse thoroughly.
What results can be expected from the first use?
From the very first wash, yellow tones appear neutralized and the color looks clearer. Whites appear purer, greys deeper, and the hair visibly more luminous.
Results may vary depending on the intensity of the yellowing, the porosity of the hair fiber, and the leave-on time of the purple shampoo.
Do GRIS anti-yellowing treatments dry out hair?
No. The GRIS anti-yellowing purple shampoo has been formulated to correct yellow tones without accentuating the natural dryness of gray and white hair.
Its gentle cleansing base is combined with glycerin, hyaluronic acid, amino acids, and hydrolyzed proteins. These active ingredients help preserve the moisture, suppleness, and quality of the fiber during color correction.
How do I apply the GREY anti-yellowing purple shampoo?
Start with a first wash using the GRIS hydrating care shampoo. Rinse thoroughly, then apply the purple anti-yellowing shampoo to wet hair.
Gently massage the scalp and distribute the lather through the lengths. Leave on for two to three minutes, then rinse carefully.
Follow with the GRIS conditioner to nourish the hair fiber and make detangling easier.
How often should I use anti-yellowing shampoo?
Use the GRIS purple anti-yellowing shampoo approximately once a week. The frequency can be adapted based on the intensity of yellow tones and hair porosity.
It is not necessary to use it with every wash. Alternate it with the GRIS moisturizing care shampoo to preserve the fiber's balance and prevent excessive buildup of purple pigments.
Do GRIS skincare products have a natural composition?
Yes. GRIS hair care products are made with 97% ingredients of natural origin. They are formulated without sulfates, silicones, and parabens.
Are GRIS hair care products for dry hair vegan?
Yes. GRIS products are not made with animal-derived ingredients and are not tested on animals.
