Your hair, a crown you never remove, demands meticulous care to maintain its health and vibrancy. Yet, the relentless assault of hard water poses a formidable threat, exacerbating damage and leaving behind a trail of woes—from brittle strands to lacklustre locks. Calcium, the most abundant mineral in your body, is crucial for maintaining strong bones and has long been championed as a key component of a healthy diet. However, when it comes to your tresses, excess calcium abundant in hard water weakens the protein structure of your hair. Fortunately, Kérastase presents the solution: the new Première collection, meticulously crafted to combat the detrimental effects of hard water on your hair.

For optimised results with the Premiere range, the key is layering so that the active ingredients are able to penetrate from the outer cuticle to the inner core. Here, we’ve formulated a fail-proof routine for you that targets stubborn calcium buildup, delivering salon-worthy locks without ever leaving the comfort of your home.

Pre-Treat & Cleanse

Revamping delicate, over-processed or bleached hair can be a real hassle, especially since it’s more porous and absorbs three times more calcium compared to healthy hair. But fear not, the Première Pre-Shampoo Decalcifiant Hair Treatment is specially formulated to tackle this issue head-on. Containing a robust blend of citric acid and glycine, the concentrate removes excess calcium and repairs damaged hair, restoring vitality with just a 5-minute application on dampened hair. Layer up with the Première Shampoo Decalcifiant, a sulphate-free formula that gently cleanses, focusing on the cuticle layer while decalcifying the inner layer, resulting in smoother, shinier hair with consistent use.

Treat & Nourish

For when your hair is looking for the ultimate rejuvenation, indulge in the Premiere Fondant Fluidite Reparateur Conditioner or the Première Mask. The conditioner restores elasticity and moisture to over-processed hair, leaving it smoother and shinier. Plus, it's lightweight and contains glycine for added hydration and strength. On the other hand, the mask, enriched with peptides, deeply conditions and protects the locks against breakage, visibly reduces the appearance of split ends. Whether you choose the conditioner or the mask depends on your hair type and needs. After rinsing out the Pre-Shampoo Treatment and shampoo, apply either the conditioner or mask accordingly, leaving it on for a few minutes to let the hydration sink in.

Style & Protect

When it comes to protecting your hair from heat styling, environmental damage, look to the Première Sérum Filler Fondamental and Première Huile Gloss Réparatrice. The serum shields hair from humidity and heat up to 450 degrees Fahrenheit, leaving it visibly frizz-free, while the oil offers intense shine that restores and seals split ends. For a “straight out of a hair commercial” moment, start with the lightweight Première Sérum Filler Fondamental for heat protection during styling. Layer with the luxurious Première Huile Gloss Réparatrice to add gloss, smoothness, and manageability.
