LAYER 1 - ACTIVATE

 

Start with the Kérastase Première Concentré Décalcifiant Ultra Réparateur, a pre-shampoo concentrate that is the clarifying hero of the collection. Use on slightly wet/damp hair and should not be rinsed before applying the shampoo (layer 2).

With 3% citric acid and 5% glycine, it decalcifies your hair reducing stiffness, boosting shine, recreating 99%* of hair’s original strength and reducing breakage by 93%*.

LAYER 2 - CLEANSE

Our Kérastase Première Bain Décalcifiant Réparateur should be applied directly on top of the Concentré (you can add a little water to emulsify if needed).

Its creamy texture and voluptuous foam gently cleanses away calcium overload and neutralizes dullness and breakage. Hair is left healthier, shinier, and renewed.

STEP 3 - TREAT

Once hair is towel-dried you can layer on the Kérastase Première Fondant Fluidité Réparateur, or the Masque Filler Réparateur.

The lightweight formula of the conditioner quickly gets to work to restore moisture and fluidity. In fact, hair is left 7 x smoother*, 82% shinier* and with 86% more moisture*.

The rich, creamy mask should be left on towel-dried hair for 5 minutes in order to penetrate fibers to repair and rebuild inner strength.

 

STEP 4 - FINISH

Calcium doesn’t just cause breakage, it enhances damage and dryness leading to frizz, so our Kérastase Première Sérum Filler Fondamental is designed to repel humidity and protect against heat up to 230 degrees.

Huile Gloss Réparatrice is a nourishing oil that seals spit ends and boosts shine. It’s the perfect addition to polish hair after heat styling or to tame flyaways
