KERASTASE Première Ultimate Decalcifying Repair 4-Piece Set

KERASTASE Première Ultimate Decalcifying Repair Set

The KERASTASE Première Ultimate Decalcifying Repair Set is a complete professional routine for damaged, bleached, over-processed and highly porous hair, combining four complementary Première treatments to help tackle persistent damage from the first treatment step through to the final glossy finish.

Damaged hair can become increasingly porous and vulnerable to excess calcium accumulation from water. The Première ritual is designed around decalcifying damaged hair and restoring strength, softness and movement, while helping reduce breakage and improve the appearance of compromised lengths.

Decalcify → Cleanse → Repair → Strengthen → Smooth → Gloss

What's Included?

KERASTASE Première Concentré Décalcifiant Ultra-Réparateur Pre-Shampoo Treatment 250ml

The first and most intensive decalcifying pre-shampoo step.

Designed for damaged and over-processed hair, this treatment helps remove excess calcium buildup while supporting weakened hair fibres. It prepares the hair for the Bain Décalcifiant Réparateur, which is applied directly over it before rinsing.

KERASTASE Première Bain Décalcifiant Réparateur Repair Shampoo 250ml

A professional decalcifying repair shampoo that cleanses damaged hair while continuing the Première decalcifying action.

Used directly over the Concentré, it helps remove excess calcium buildup and impurities while supporting stronger, smoother and healthier-looking hair.

KERASTASE Première Masque Filler Réparateur Repairing Hair Mask 200ml

An intensive anti-breakage repairing mask for damaged, porous and over-processed hair.

Formulated with Peptide and Glycine, its rich texture helps rebuild weakened hair, smooth porous fibres and provide intensive conditioning. KERASTASE reports 93% less breakage and hair that is 99% stronger under instrumental testing.

KERASTASE Première Huile Gloss Réparatrice Repair Hair Oil 30ml

The luxurious finishing step of the routine.

This lightweight repairing oil helps smooth damaged lengths, control frizz, seal the appearance of split ends and restore high-gloss shine without leaving hair feeling unnecessarily heavy.
