Premiere 1 Decalcifying System Reparative Pre-Shampoo Treatment - 33.8 oz

Elevate your salon's damaged hair services with the Kérastase Première Concentré Décalcifiant Ultra-Réparateur, the high-concentration, professional-size pre-shampoo treatment that targets the root cause of persistent hair damage: calcium buildup from hard water. Damaged hair is porous, absorbing up to 3 times more calcium than natural hair, which accumulates both inside and outside the fiber, leading to rigidity, dullness, and massive breakage. This generous 33.8 oz backbar bottle is the powerhouse of the Première system, utilizing a concentration of pure acids to perform a dual-action repair—first decalcifying, and then intensely reinforcing the hair's structure from the core. It is the essential first step that fundamentally resets the hair's integrity before shampooing.

The profound effectiveness of this concentrated gel lies in the strategic combination of its key ingredients. Citric Acid, a powerful organic acid, works to actively chelate (bond with and remove) the destructive calcium overdose from the hair fiber, immediately neutralizing the stiffness and dullness that hard water creates. Once the outer barrier of calcium is lifted, the amino acid Glycine penetrates deep into the inner layer of the hair, where it works to reconnect and repair broken keratin links, reinforcing the hair's structure to prevent future damage. The ultimate result of this dual-action technology is a dramatic and measurable transformation: the product helps restore up to 99% of hair's original strength and dramatically reduces breakage.

This 33.8 oz professional size ensures you can deliver this revolutionary service consistently and economically, maximizing client satisfaction and salon profitability. For optimal results, this transparent gel should be applied generously to damp hair before shampooing and left on for five minutes; critically, it should not be rinsed, but instead immediately layered with the Première Bain Décalcifiant Réparateur Shampoo for an amplified decalcifying effect. This pre-shampoo concentration, paired with the full routine, dramatically reverses persistent damage, leaving hair 93% less prone to breakage, 75% shinier, and visibly smoother and healthier—as if renewed to its première state.

Highest Concentration Dual-Action Repair: This treatment features the highest concentration of Citric Acid to aggressively decalcify the hair fiber from damaging mineral buildup, which is immediately followed by Glycine penetrating the cortex to reconnect broken keratin bonds. This powerful dual approach ensures persistent damage is reversed, resulting in a clinically measured restoration of 99% of hair's original strength.

Essential Layering for Maximum Efficacy: Designed as a crucial pre-shampoo step, the treatment is engineered to be layered with the Première Bain Décalcifiant Réparateur Shampoo without rinsing, creating a superior, concentrated decalcifying action. This layering technique maximizes the removal of calcium overdose, a necessary step for clients with highly damaged or over-processed hair that absorbs 3x more hard water minerals.

Dramatic Breakage and Shine Improvement: By reinforcing the internal structure and removing the external rigidity caused by calcium, the product profoundly improves the hair's structural integrity. Clinical testing shows results of 93% less breakage and 75% more shine, offering clients visible and immediate proof of the treatment’s rejuvenating power.

Economical Professional Backbar Size: The expansive 33.8 oz (1000 ml) size is the most cost-effective option for professional use, ensuring a low cost-per-service and maximizing salon profit margins. This high-yield volume is necessary for consistently providing this intensive, high-demand restorative treatment to a wide clientele base.

Reverses Stiffness and Improves Texture: The decalcifying action instantly reverses the stiff, rigid, and rough texture that hair develops due to mineral buildup, allowing the hair to regain its natural fluid movement. This preparation step leaves the hair softer and significantly more manageable, optimizing the results of subsequent conditioning and styling products.
