Kérastase Première is formulated for all types of damaged hair — bleached, colour-treated, over-processed, and rebonded. Its dual-action formula removes calcium mineral buildup deposited by hard water while also reconstructing broken hair bonds, resulting in stronger, smoother, and shinier hair.

Yes. The Kérastase Première shampoo is sulfate-free (no SLS or SLES), making it gentle on the hair fibre and safe for colour-treated hair. The full ritual is designed to cleanse without stripping colour or adding further damage.

Yes. The entire Première collection is colour-safe. The sulfate-free shampoo and conditioning steps are formulated to preserve colour vibrancy while actively repairing and decalcifying the hair fibre — ideal for bleached, highlighted, or salon-coloured hair.

Both address bond damage, but through different mechanisms. Kérastase Première adds a unique decalcifying step that removes hard-water mineral buildup from the hair fibre — something K18 does not target. K18 uses a patented peptide (K18PEPTIDE™) to reconnect broken polypeptide chains. Première uses a multi-step ritual (pre-shampoo through masque), while K18 is a leave-in applied after washing. The two can complement each other, but Première is particularly suited when mineral buildup from hard water is a concern.

Start by applying the pre-shampoo treatment to dry or damp hair before washing — this step decalcifies and prepares the hair. Follow with the sulfate-free shampoo, then the conditioner. Finish with the leave-in lotion and, optionally, the repairing hair oil on damp or dry hair. The masque can replace the conditioner once or twice a week for deeper repair.

Kérastase Première is available at HairMNL.com, an authorised Kérastase retailer in the Philippines. Individual products and the discovery set can be purchased online and delivered nationwide.
