The Kérastase Première Reparative Duo is your damaged hair’s ultimate comeback story. This powerful pre-treatment and shampoo combination targets the hidden culprit behind stubborn breakage, dullness, and stiffness: calcium buildup from hard water. Whether your hair has been through the bleaching wringer, suffered from over-processing, or just feels impossibly damaged, this duo works in perfect harmony to dissolve calcium deposits while rebuilding your hair’s strength from the inside out. Say goodbye to that crunchy, lifeless feeling and hello to hair that actually bounces back.

What’s Included:

  • Première Concentré Decalcifiant Ultra-Réparateur (300ml) – Decalcifying pre-shampoo treatment
  • Première Bain Decalcifiant Réparateur (250ml) – Decalcifying shampoo

Perfect If You Have:

  • Hair that feels stiff, crunchy, or lacks movement
  • Anyone living in hard water areas (most of Canada!)
  • Over-processed, bleached, or chemically treated hair
  • Hair that won’t hold styles or looks dull despite good products

Why You’ll Love It:

  • Removes stubborn calcium buildup that’s sabotaging your hair goals
  • Restores keratin links for stronger, more resilient strands
  • Eliminates stiffness and brings back natural movement
  • Works on all hair types, especially over-processed, coloured hair and bleached hair
  • Sulphate-free formula that’s gentle yet incredibly effective
  • Professional salon treatment you can do at home

Key Ingredients:

  • Citric Acid: Acts like a powerful decalcifying agent, dissolving calcium deposits that make your hair feel stiff and look dull.
  • Glycine: This amino acid penetrates deep into the hair fibre to rebuild keratin links from within, restoring your hair’s natural strength and elasticity.

Pomme Tip:

Don’t skip the 5-minute wait time with the pre-treatment! This isn’t just another step to rush through – those potent acids need time to dissolve the calcium and penetrate deep into your hair shaft. Think of it as meditation time for your hair. And remember, don’t rinse between steps – layer the shampoo right on top for maximum effectiveness!

    • Do NOT rinse out

    Step 2: Shampoo (Bain Décalcifiant Réparateur)

    • Apply the shampoo directly on top of the pre-treatment
    • Add a little water and massage gently to create a lather

    • Rinse thoroughly with lukewarm water
    • Follow with the Première conditioner or mask, or pair it with your favourite Kérastase conditioner or mask!

    Pro Tips:

  • Please see individual product pages for ingredients. 

    1. How often should I use the Première Duo? Start with 1-2 times per week and adjust based on your hair's damage level. If you're dealing with severe calcium buildup or live in an area with very hard water, you might benefit from using it more frequently initially, then scaling back to weekly maintenance.
    2. Do I really need both products, or can I just use one? While each product is effective on its own, they're designed to work as a team. The pre-treatment does the heavy lifting of calcium removal and deep repair, while the shampoo continues the decalcifying process and restores keratin links. Using them together gives you the full calcium-fighting, hair-repairing experience.
    3. Can I use this on fine hair? Absolutely! This duo works on all hair types. Fine hair actually benefits greatly because calcium buildup can weigh down delicate strands and make them look flat. You might find your fine hair has more volume and movement after removing that calcium coating.
    4. How long before I see results? You'll notice softer, more manageable hair immediately after your first use – that's the calcium being dissolved and washed away. Here's what to expect:
      • First use: Immediate softness and easier detangling
      • Week 1-2: Noticeable reduction in stiffness, more natural movement
      • Week 3-4: Significantly less breakage, improved shine
      • Week 6+: Stronger, more resilient hair that holds styles better

      The real strength-building magic happens over 4-6 weeks of consistent use, when you'll notice hair that actually bounces back from styling and feels healthier overall.

    5. Should I follow up with conditioner after using this duo? Yes! While the shampoo is gentle and repairing, you'll still want to follow with a conditioner or mask. We love pairing this duo with the Première Fondant or Masque for the complete calcium-fighting, hair-repairing routine.
    6. Will this strip my colour? Not at all! The sulphate-free formula is completely safe for colour-treated hair. In fact, by removing calcium buildup that can make colour look dull and muddy, many clients find their colour looks more vibrant and true-to-tone after using this duo.
    7. What makes this different from other clarifying shampoos? Most clarifying shampoos just remove product buildup from the hair's surface. The Première Duo goes deeper – it actually dissolves mineral deposits that have penetrated into your hair shaft and repairs the damage they've caused. It's like the difference between wiping down your counters versus deep-cleaning your entire kitchen.
    8. How is this different from other hair treatments? 

      vs. Purple shampoo: Purple shampoo targets colour brassiness, which targets structural damage from minerals
      vs. Protein treatments: Unlike protein treatments that can overload hair, this removes what's blocking absorption first
      vs. Generic clarifying shampoos: More targeted approach that strips buildup while simultaneously repairing damage
