Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment is a dual action strengthening, decalcifying pre-treatment for all types of damaged hair. It removes excess calcium and helps repair persistent damage, working to reconnect broken keratin links and restores hair strength and structure. Hair is left stronger, smoother, and shinier.

Why you need it

Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment is a comprehensive solution for damaged hair, especially for those dealing with the adverse effects of hard water.


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.

Formulated with 8% Pure Citric Acid & Glycine, the Pre-Shampoo Treatment works from the inside out to reset and revive your hair. 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 putting an end to that flat, lifeless look. With its lightweight, transparent gel texture, it dives deep to repair even the most stubborn damage, leaving your strands refreshed, reinforced, and totally renewed.


- Decalcifies and dramatically repairs persistent damage.
- Helps reverse stiffness and dullness
- Helps reconnect broken links between keratin chains for an inner structure reinforcement

how to use
Apply generously on wet lengths before shampoo and massage throughout. Leave on for 5 minutes. Don’t rinse. Layer Première Shampoo directly on top to maximise efficacy. Rinse and follow with Première Conditioner or Mask.

For all types of damaged hair.

Key Ingredients
Citric acid: Acts from core to surface to deeply eliminate calcium overdose and help neutralise dullness and stiffness.

Amino acid Glycine: Penetrates hair's inner layer, to help deeply repair.

As a result, this helps reconnect broken links between keratin chains, dramatically reducing breakage.

Q: Why do I use the Decalcifying Repairing Pre-Shampoo Treatment before shampoo?

A: Shampoos (and other hair products) create a protective coating on your strands, which is great—but it can also make it harder for powerful ingredients to work their magic. By applying the Pre-Treatment on wet hair before you shampoo, you're giving the actives a clear path to deeply penetrate and do their thing. More impact, more repair, more hair love!

Q: What is the leave-in time?
A: Just 5 minutes—easy! No need to rinse it out. Simply layer Première Shampoo straight on top for max impact, then rinse everything out together. Let the magic happen

Great for an extra treatment once a week

I used this once a week before the premiere shampoo to give my hair an extra treatment when I had time at the weekends. It helps my dry, blonde, highlighted hair a lot!

Great products

I really love the feeling this product gives to my hair. Hair felt more soft after even the first use. I love how easy it is to use. The fact, that you do not need to rinse it after application, but just go in with the shampoo, saves me time and effort.

Quality product

Big fan of Kérastase products & the decalcifying shampoo did not disappoint. It smells delish, its thick & creamy, used only once so far & am delighted with results, my hair is thin & bleached & is in dire need of help, only complaint is it could be too rich for my oily head so will be used as a treat once or twice a week

Pre shampoo treatment

The Kérastase Pre-Shampoo Treatment helps nourish and protect hair before washing. Use a small amount, applying it to the lengths while shampooing the roots. It adds shine, reduces frizz, and makes hair smoother—great for dry or damaged hair.

Good treatment

I would recommend this pre shampoo if your hair is damaged in any way and to prevent breakage I put it on wet hair and let it sit for 30minutes works really well with the shampoo and conditioner from this range which are excellent . A lovely treat for your hair- good for blondes.
