This collection covers a wide range of concerns. The Discipline Bain Fluidealiste Gentle Shampoo targets frizz, the Chroma Absolu range protects colour-treated hair, the Curl Manifesto Bain Hydratation Douceur Shampoo hydrates curls, the Symbiose Bain Crème Anti-Pelliculaire tackles dandruff, and the Première Decalcifying & Repairing Shampoo addresses calcium-induced damage.

Yes. Some Kerastase sulphate-free formulas are specifically developed to remove excess calcium build-up whilst helping to strengthen weakened hair fibres. These sulphate-free products gently cleanse without stripping away essential moisture, making them suitable for damaged or over-processed hair.

The Chroma Absolu range is your best starting point. The Chroma Absolu Respect Shampoo suits fine to medium colour-treated hair, whilst the Chroma Absolu Riche Chroma Respect Shampoo works better for thicker strands. Both are enriched with Amino Acid, Lactic Acid, Tartaric Acid, and Centella Asiatica, delivering over 92% colour preservation for up to six weeks. Shop the full Kérastase sulphate-free range to complete your colour-care ritual.

For most formulas in this collection, yes. Because these sulphate-free hair products are gentler than conventional cleansers, they are less likely to over-strip the scalp's natural oils, making frequent use safe. For targeted treatments, washing on alternate days is recommended to allow the formula to work optimally.

Conventional products rely on sulphates, particularly SLS and SLES, which cleanse effectively but can strip natural moisture, irritate the scalp, and accelerate colour fade. Sulphate-free hair products use milder surfactant alternatives that cleanse thoroughly without the same aggression, making them especially beneficial for sensitised, colour-treated, or chemically processed hair.

Yes, several products in this collection are ideal for post-chemical treatments. The products work together to extend smoothness and manageability. Since sulphate-free hair products do not strip the hair aggressively, they help preserve the results of straightening and keratin treatments for longer between salon visits.

For best results, follow your cleanse with a matching conditioner, hair mask and leave-in treatment designed for textured hair. Using complementary sulphate-free hair products can help improve hydration, enhance curl definition and reduce frizz while maintaining softness.

Look for SLS-free products formulated for dry, sensitive scalps that contain ingredients to target visible flakes whilst maintaining moisture. Many Kerastase sulphate-free formulas are designed to cleanse gently, soothe the scalp and help reduce dandruff without causing excessive dryness.

Yes. Some sulphate-free products in the collection are available in refillable formats, offering a more sustainable way to replenish your haircare routine whilst enjoying the same professional-quality formula.

Yes, those with sensitive scalps are among the people who benefit most from switching to sulphate-free hair care. Gentler surfactants reduce the risk of irritation and redness caused by harsh detergents. Always patch-test a new product before full application.

Many sulphate-free hair products for colour-treated hair combine caring ingredients such as amino acids, gentle acids and botanical extracts to help preserve colour vibrancy, strengthen the hair fibre and maintain healthy-looking, radiant hair.

Each collection is designed with a full ritual in mind. While one helps with maximum frizz control, another works best alongside the Chroma Absolu mask for colour longevity. Pairing complementary sulphate-free hair products ensures active ingredients work synergistically for better results.

Sustainability is central to the brand's ethos. The product is bottled in 95% recycled plastic, and a refill option is available for it. Kérastase is committed to ensuring all packaging across its sulphate-free hair products range becomes refillable, reusable, or recyclable.

Professional-grade sulphate-free hair products do tend to sit at a higher price point than mass-market alternatives, and for good reason. Each formula is developed with advanced technologies and premium active ingredients, such as Manuka Honey, Centella Asiatica, and Morpho-Kératine™, that deliver targeted, salon-quality results at home. For sensitised, colour-treated, or chemically processed hair, the investment in gentler care pays dividends in long-term hair health.
