Product Description
Due to its increased porousness, processed hair absorbs three times more calcium from water than untreated hair, which manifests internally and externally within the hair fibre. Kérastase hair treatment serum tackles this issue with a dual-action approach: its light and balmy texture effectively seals the hair cuticles, providing a protective shield for the hair's surface. Simultaneously, it penetrates the hair fibre, filling it and reinforcing its strength.
This innovative hair repair serum not only protects your hair from the damaging effects of hard water and calcium buildup but also shields it from humidity and heat up to 230°C. It eliminates frizz leaving your hair smooth, supple, and easy to style.

STEP 1: Apply to freshly washed and towel-dried hair. Dispense the anti-breakage hair serum into your palms, then evenly distribute it throughout your hair, focusing on mid-lengths to ends. Use a wide-tooth comb or your fingers to detangle and ensure thorough coverage.
STEP 2: Leave the product in your hair without rinsing. This allows the formula to deeply penetrate each strand, providing nourishment and protection from within. Complement this routine with our range of hair styling products.
For enhanced care for your bleached or damaged hair, combine with the rest of the Première products. Unlock the full potential of the layering technique with these steps: Begin with the pre-shampoo treatment, Kérastase Première Intensive Repairing Concentrate, followed by the shampoo, Kérastase Première Decalcifying & Repairing Hair Shampoo, without rinsing off the Concentré. Next, apply the conditioner or mask for added nourishment before concluding with Kérastase Première Intensive Repairing Serum as the final step for repair.

How To Dramatically Reverse Persistent Damage?
Kerastase discovered the reason behind damage that keeps coming back: CALCIUM!
3x
More calcium is absorbed with damaged hair as it is more porous (vs healthy hair), leading to a calcium overdose
PERSISTENT
Damage happens when calcium sneaks in-between keratin chains at every contact with water, breaking their links, making hair rigid, stiff and easy to break
BUILD-UP
Of calcium on the outside makes hair rough and dull
Pure Acids Concentration
Free hair from calcium overdose with citric acid, an organic compound that works from the hair's core to its surface. This natural acid effectively neutralises dullness and stiffness, revitalising your hair's appearance and texture. As calcium is eliminated, Glycine, an essential amino acid, seamlessly penetrates the hair's inner layers, initiating a deep reparative process. This transformative action re-establishes the broken links between keratin chains, leading to a significant reduction in breakage.
