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 - Shampoos
Why use shampoos specially designed for gray and white hair?
As melanin gradually decreases, the structure of the hair changes. The fiber generally becomes more porous, retains water less effectively, and is more sensitive to external aggressors.
Gray and white hair can thus become drier, coarser, and more prone to frizz. Pollution, limescale, ultraviolet rays, or heat can also dull its color and encourage the appearance of yellow tones. GRIS shampoos address these two needs: preserving the fiber's hydration and revealing the purity of its color.
What is the difference between the moisturizing care shampoo and the GRAY anti-yellowing purple shampoo?
The GRIS hydrating care shampoo gently cleanses, helps the fiber retain its moisture, and prepares hair for subsequent treatments.
The GRIS purple anti-yellowing shampoo acts on color. Its purple pigments neutralize yellow and golden undertones to reveal a purer white and a more luminous gray.
The two shampoos are complementary: the first cares for the balance of the fiber, while the second corrects unwanted tones.
Which GREY shampoo should I choose for my hair?
Choose the GRIS moisturizing care shampoo if your hair is dry, coarse, dull, or prone to frizz. It serves as the primary shampoo in the routine and can be used with every wash.
Use the GRIS purple anti-yellowing shampoo when yellow or golden tones appear on gray and white hair. It is used occasionally, as a supplement to the moisturizing shampoo, depending on your color needs.
Can both GREY shampoos be used during the same wash?
Yes. Both shampoos have been designed to be used successively as part of the anti-yellowing ritual.
The GRIS moisturizing care shampoo performs the first wash: it removes impurities and prepares the hair fiber. The GRIS anti-yellowing purple shampoo is then used as a second wash to neutralize yellow tones. This combination makes it possible to correct the color while preserving the softness and hydration of the hair.
How do I use both GREY shampoos in the same routine?
Always start with the GRIS hydrating care shampoo.
Wet your hair thoroughly, apply a small amount of hydrating care shampoo, wet again if necessary, then gently massage the scalp. Work the lather through the lengths, then rinse thoroughly.
Next, apply the GRIS anti-yellowing purple shampoo. Massage gently to distribute the pigments throughout the hair, leave on for two to three minutes, then rinse carefully.
Follow with the GRIS conditioner on the lengths and ends, then finish with the GRIS leave-in day care.
How often should I use GRIS shampoos?
GRIS moisturizing care shampoo can be used with every wash, about twice a week or as needed by your hair.
GRIS purple anti-yellowing shampoo is generally used once a week, depending on the intensity of the yellow tones. During the anti-yellowing ritual, it replaces the second application of the moisturizing care shampoo. It is not necessary to use it with every wash.
How does the GRIS hydrating care shampoo act on the hair fiber and scalp?
Its gentle cleansing base cleanses hair without compromising its moisture balance. Low molecular weight hyaluronic acid, Prodew® 500, vitamin B12, and Nutripeptide GR help preserve the hydration, suppleness, and quality of the fiber.
The formula also combines KeraScalp® and the copper peptide GHK-Cu, two active ingredients selected to care for the scalp environment. Hair gradually appears softer, more supple, and more luminous.
How does GRIS purple anti-yellowing shampoo neutralize yellow tones?
Its action is based on the principle of colorimetry. Since purple is the complementary color to yellow, its pigments help to visually correct the yellow and golden tones that can dull gray and white hair.
The color appears cooler, purer, and more luminous, with no lasting change to the hair's natural shade.
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 is better at correcting orange or brassy tones, which are often found in lightened brown hair. To remove yellowing from grey and white hair, a purple shampoo is therefore generally more suitable.
Does the GRIS anti-yellowing purple shampoo color white hair?
No. This is not a color shampoo. The violet pigments are deposited temporarily on the surface of the fiber to visually neutralize yellow tones, without permanently changing the hair color.
On very light or particularly porous hair, an excessive processing time may leave a slight, temporary violet tint. Follow the recommended processing time and rinse thoroughly.
Do GRIS shampoos dry out or weigh down the hair?
No. Both formulas combine mild cleansing agents with moisturizing, biomimetic active ingredients. They cleanse and enhance radiance without accentuating the natural dryness of gray and white hair.
Hyaluronic acid, glycerin, amino acids, and hydrolyzed proteins help preserve the moisture and suppleness of the fiber. After rinsing, the hair remains light, soft, and easy to style.
Do GRIS shampoos have a natural composition?
Yes. Both GRIS shampoos are made with over 97% ingredients of natural origin. They are formulated without sulfates, silicones, and parabens.
Are GRIS shampoos vegan?
Yes. Both GRIS shampoos contain no ingredients of animal origin and are not tested on animals.
