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 - SHINE AND RADIANCE CARE
Why can gray and white hair become dull?
As melanin gradually decreases, the structure of the hair changes. The fiber generally becomes more porous and its surface more irregular. Consequently, it reflects light less uniformly.
Pollution, limescale, ultraviolet rays, heat, and product residue can also dull the radiance of gray and white hair. Yellow tones may appear and make the color look less luminous.
Which GRAY hair care products should you choose to revive the shine of gray and white hair?
GRIS care products work complementarily to improve hair fiber quality and color purity:
- The GRIS moisturizing care shampoo gently cleanses and helps preserve hydration.
- The GRIS anti-yellowing purple shampoo neutralizes the yellow undertones that dull the hair.
- The GRIS conditioner nourishes the lengths and smooths the appearance of the fiber to better reflect light.
- The GRIS leave-in day care prolongs hydration and revives radiance between washes.
Which GRIS routine should I choose for dull, lackluster hair?
The GRIS radiance duo is suitable if your priority is to cleanse the hair fiber and neutralize yellow undertones.
Choose the GRIS softness & radiance trio if your dull hair is also dry, coarse, or difficult to detangle.
To address shine, hydration, nourishment, and frizz on a daily basis, choose the signature GRIS routine. It brings together the four treatments in the range.
How does the GREY moisturizing care shampoo revive hair radiance?
A well-hydrated fiber has a smoother, more uniform surface. It reflects light more consistently and naturally appears shinier.
The moisturizing GRIS shampoo cleanses without being harsh. Low molecular weight hyaluronic acid, Prodew® 500, and Nutripeptide GR help preserve the hydration and quality of the fiber. Hair regains its softness, suppleness, and radiance from the very first wash.
How does the GREY anti-yellowing purple shampoo work on dull hair?
Its purple pigments visually neutralize yellow and golden undertones according to the principles of color theory. They reveal a purer white and a deeper gray.
Its gentle cleansing base is combined with moisturizing, biomimetic active ingredients. It corrects color without compromising the suppleness or comfort of the hair fiber.
How do I use GRIS products to restore shine?
Start with the GRIS hydrating care shampoo. During your anti-yellowing ritual, use the purple anti-yellowing shampoo for the second wash. Leave on for two to three minutes, then rinse thoroughly.
Next, apply the GRIS conditioner to the lengths and ends. Leave on for two to three minutes before rinsing.
Finish with a small amount of GRIS leave-in day cream on damp hair. Between washes, apply a small amount to dry hair to revive softness and shine.
How often should I use GRIS radiance treatments?
The GRIS moisturizing shampoo and conditioner can be used with every wash, about twice a week or as needed for your hair.
The GRIS purple anti-yellowing shampoo is generally used once a week. Its frequency can be adjusted based on the intensity of yellow tones.
The GRIS leave-in day treatment can be applied daily to damp or dry hair.
What results can be expected on dull hair?
From the very first ritual, the hair fiber appears softer, more supple, and silkier. When a purple shampoo is used, yellow undertones are neutralized and the color gains clarity.
With continued use, the hair appears more uniform and reflects light better. White looks purer, gray looks deeper, and the hair is visibly shinier.
Does GRIS purple shampoo color white hair?
No. GRIS purple anti-yellowing shampoo is not a color-depositing shampoo. Its pigments are temporarily deposited on the surface of the hair fiber to visually neutralize yellow undertones.
On very light or particularly porous hair, an excessive processing time may cause a slight, temporary violet tint to appear. Follow the recommended processing time and rinse thoroughly.
Do GRIS shine treatments dry out or weigh down the hair?
No. The formulas combine hydrating and nourishing active ingredients to preserve the softness and suppleness of gray and white hair.
Hyaluronic acid, biomimetic amino acids, organic shea butter, and organic castor oil care for the fiber without leaving a greasy finish. Hair remains light, fluid, and naturally luminous.
Are GRIS anti-frizz treatments suitable if I only have a few rebellious gray hairs?
Yes. Even when few in number, gray hairs can have a drier, coarser, or more unruly texture than pigmented hair.
GRIS care products help harmonize the hair's feel and tame those rebellious strands. The GRIS leave-in day treatment, in particular, can be applied in very small amounts and targeted specifically to the affected hairs, without weighing down the rest of your hair.
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 skincare products do not contain animal-derived ingredients and are not tested on animals.
Are GRIS hair care products for dull hair suitable for pregnant women?
Yes. They are suitable for pregnant women.
As with any cosmetic product, follow the precautions for use and seek advice from a healthcare professional in case of particular sensitivity or doubt. Avoid contact with the eyes and do not apply the products to an irritated or damaged scalp.
