Note:

• What hair concern is the Kérastase Première Repairing Shampoo designed for?

  The Kérastase Première Repairing Shampoo is a professional treatment explicitly engineered for over-processed, bleached, or severely damaged hair structures. It functions as a calcium removing shampoo for damaged hair, clearing away mineral deposits from tap water that make hair stiff and brittle.

• How should I use the Kérastase Bain Décalcifiant Réparateur for best results?

  Apply a small, coin-sized amount to completely wet hair directly on top of the Première Pre-Shampoo Treatment without rinsing first. Massage both products together into your scalp and lengths to form a rich lather, then rinse thoroughly. Follow with a second smaller application of shampoo alone if needed.

• Why is removing calcium buildup so important for damaged hair?

  Porous, chemically damaged hair absorbs up to three times more calcium from tap water than healthy hair. This mineral buildup accumulates inside the hair shaft, making the strands rigid, rough, and highly prone to severe mid-length snapping. Removing it restores natural flexibility and strength.

• Will this broken hair bond repair shampoo make my fine hair feel heavy?

  No, this advanced formula is designed as a lightweight, non-greasy gel cleanser. It deeply removes hard mineral buildup and reconnects broken keratin links, but rinses completely cleanly away with water, leaving fine hair structures looking instantly refreshed, voluminous, and full of soft body.

• Can I use this clarifying decalcifying cleanser every single day?

  Yes, it is perfectly safe for daily use if your personal hair care routine requires frequent washing. The gentle cleansing base respects the delicate moisture barrier of your scalp while continuously working to rebuild structural strand resilience against styling damage and friction.

• Is the Kérastase Première Repairing Shampoo safe for coloured or bleached hair?

  Absolutely. Heavily bleached or highlighted hair is naturally porous and suffers the most from calcium rigidness. This shampoo works to rescue those fragile fibers and restore movement, making it an exceptional defensive step for processed hair without shifting or fading your colour.

• What are the main active ingredients inside this formula?

  The formula relies on a powerful combination of 3% Citric Acid to effectively dissolve the rigid calcium buildup from the hair shaft, alongside 5% Glycine, an essential amino acid that penetrates the inner core to reconnect broken keratin bonds and rebuild structural strength.

• What is the exact size of the Kérastase Première Shampoo bottle?

  The standard retail size bottle of this professional decalcifying cleanser contains 250ml of product. Because it forms an incredibly rich, concentrated lather with only a small portion, a single bottle lasts through many weeks of consistent daily wash cycles.

• Do I always need to use the Pre-Shampoo Treatment with this shampoo?

  While you can use the shampoo completely on its own as a great daily cleanser, layering it directly over the Concentré Pré-Shampoo Treatment creates an intensive bond-repairing system that delivers significantly stronger, more dramatic decalcifying and restructuring results.

• Does this product help reduce split ends and styling breakage?

  Yes, by removing the harsh mineral buildup that makes hair rigid and snapping, this shampoo restores natural elasticity to the entire hair fiber. This directly prevents future split ends from forming and dramatically lowers daily breakage from brushes or styling tools.

• Is this shampoo free from silicones and parabens?

  Yes, this formula is expertly crafted completely free from silicones and parabens. This allows the clean, active amino acids to directly penetrate and bond with the weak hair structure without creating any heavy external blockages over time.

• What fragrance profile does the Kérastase Première collection feature?

  It features a gorgeous, sophisticated fragrance profile inspired by luxury summer styles. It blends refreshing top notes of mandarin orange and juicy citrus fruits with a heart of delicate orange blossoms and a warm woody base, leaving a luxurious aroma on your hair.
