Kerastase Premiere Duo Shampoo Routine

roduct Description

Our first pre-shampoo treatment that removes excess calcium and helps repair all types of damaged hair.​

Hard water with calcium can further damage already delicate over-processed or bleached hair. Because it’s more porous, damaged hair can absorb up to 3 times more calcium than natural hair. This treatment formulated with a concentration of pure citric acid and glycine has a dual action: it decalcifies hair from this calcium overdose, and works to repair it from the inside out, restoring hair strength, and reversing its stiff, dull appearance.​

With its transparent gel texture, this pre-treatment helps repair persistent damage, working to reconnect broken keratin links and reinforce hair strength and structure. Hair is left stronger, healthier-looking, and shinier – as if renewed. Leave on Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment without rinsing, and layer with Kérastase Première Decalcifying Repairing Shampoo. Team with Kérastase Première Anti-Rigidity Decalcifying Repairing Conditioner as a final step

.​Step 1:

Apply generously on wet lengths before shampoo and massage throughout.

Step 2:
Leave on for 5 minutes. Don’t rinse.

Step 3:
Layer Première Shampoo directly on top to maximise efficacy.

Step 4:
Rinse and follow with Première Conditioner or Mask.


Product Description

Kérastase Première Decalcifying Repairing Shampoo is a decalcifying, repairing shampoo for all types of over-processed or damaged hair. This professional-level shampoo gently cleanses the scalp and hair while removing excess calcium*, which further weakens treated hair.

*Instrumental test, when using full Première routine​

A white creamy shampoo that transforms into a luxurious foam, its dual action fights the calcium overdose from hard water that attacks your already damaged or bleached hair, leaving it dull, lifeless, and limp. It also helps restore keratin links within the hair shaft, repairing hair at the core. Your hair feels smooth and manageable, shiny and bouncy.​

We recommend layering Kérastase Première Decalcifying Repairing Shampoo on top of Kérastase Decalcifying Repairing Pre-Shampoo Treatment without rinsing first for maximum results. Team with other products from the Première range, like the Anti-Breakage Repairing Filler Mask.​
Step 1:
Apply on wet hair, layered on top of the Decalcifying Repairing Pre-Shampoo Treatment.

Step 2:
Massage and emulsify. 

Step 3:
Rinse thoroughly. 

Step 4:
Follow with Première Conditioner or Mask.

How To Dramatically Reverse Persistent Damage?

Want to know the reason behind damage that keeps coming back? CALCIUM!


Damaged hair is porous and absorbs up to ​
more calcium from water (vs healthy hair) leading to a calcium overdose.


At each contact with water, calcium accumulates creating​
damage. Calcium sneaks in-between keratin chains, and breaks their links, making hair rigid, stiff and easy to break.


On the outside, calcium
on the scales, making hair rough and dull.

8% pure acids concentration​
Free hair from calcium overdose with citric acid, an organic acid that acts from core to surface, to neutralise dullness and stiffness. Once excess calcium is removed, Glycine, an amino acid, penetrates hair's inner layer to help deeply repair. As a results this helps reconnect broken links between keratin chains, helping to reduce breakage.
