Key Ingredients

Glycine

Upon the removal of calcium, it infiltrates the hair's inner layer, aiding in the reestablishment of connections between keratin chains. This leads to a notable decrease in hair breakage.

What does the Kérastase Première Intensive Repairing Concentrate do?

The Kérastase Première Intensive Repairing Concentrate is a meticulously crafted pre-wash glycine hair treatment designed to decalcify and restore various types of damaged hair. Its professional-grade formula boasts a potent concentration of pure acids, aiming to both decalcify and effectively address persistent damage. The formula in this pre-shampoo treatment penetrates deeply into the hair, liberating it from calcium excess, relieving stiffness and dullness, and expertly reconnecting fractured links between keratin chains. The result is visibly stronger, healthier-looking, and shinier hair, reflecting a renewed vitality. Read expert tips on how to get healthy hair.

Why is the Kérastase Première Intensive Repairing Concentrate used before shampooing?

Using the Kérastase Première Intensive Repairing Concentrate before shampooing is strategic due to the coating effect that shampoos, like other hair care products, can have on the hair fibre. While these products provide a protective layer, they simultaneously create a barrier that makes it challenging for active ingredients to penetrate effectively. By using this pre-wash glycine hair treatment on wet hair before shampooing, we optimise the penetration of actives into the hair. This serves as the initial step to deliver an ultra-concentrated boost of actives, reaching up to the core of the fibre. When layered with the Kérastase Première Intensive Repairing Concentrate or Mask, this pre-shampoo treatment for damaged hair offers a dual massage, enhancing the absorption of actives for an even more effective result. To complete the Kérastase Première protocol, you can apply the Première Anti-Frizz Hair Serum and/or a few drops of Première Hair Repairing Oil to nourish and moisturise both the lengths and split ends. Learn how to get rid of split ends.

How long should I leave the Kérastase Première Intensive Repairing Concentrate on my hair?

Allow the Kérastase Première Intensive Repairing Concentrate to remain on your hair for 5 minutes. Do not rinse immediately. Instead, layer the Première Repairing Shampoo directly on top of this pre-wash glycine hair treatment to optimise effectiveness. Afterward, rinse thoroughly.

How much Kérastase Première Intensive Repairing Concentrate should I use?

Use 15 to 25ml (equivalent to 4/5 pumps) of the Kérastase Première Intensive Repairing Concentrate and apply with a brush. No rinsing is required.

Can I use the Kérastase Première Intensive Repairing Concentrate on its own?

We recommend using other products from the Kérastase Première range along with the Kérastase Intensive Repairing Concentrate to decalcify and treat damaged hair. Each product in the range plays a crucial role in ensuring optimal decalcification and repair results. Learn the signs of damaged hair.
