Kerastase Premiere Anti-Breakage Repairing Filler Mask (6.76 oz) - The Filler for Flawless Fiber, Rebuild from the Core

It is time to undo the years of damage that leave your hair brittle, rigid, and dull. The Kérastase Première Anti-Breakage Repairing Filler Mask is the ultimate weekly ritual for all types of damaged hair-especially those lengths that have been bleached, colored, or over-processed and are craving serious internal repair. Unlike many deep conditioners that only smooth the surface, this luxurious, rich mask actively works to fill and reinforce the fiber, acting as an internal scaffolding system to restore strength and suppleness that has been lost due to external aggressors and, most importantly, chronic calcium buildup from hard water. The difference between weak, limp hair and hair that truly resists breakage starts here, in this pot of transformative repair.

The secret to this intense repair lies in its concentrated blend of high-performance active ingredients. The formula features Peptides, which are amino acid chains known to refill the hair fiber's surface, smoothing out the rough, porous texture of damaged strands and reducing split ends. Working in tandem is the mighty Glycine, an amino acid small enough to dive deep beyond the cuticle and penetrate the inner cortex, actively reconnecting the broken keratin chains that calcium overdose has shattered. This dual-action filler technology ensures that the hair is repaired both on the surface and at its core, restoring up to 97% of the fiber's inner structure. This mask is the definition of a deep treatment, leaving hair 86% more hydrated and dramatically reducing breakage.

To truly maximize your results, use this luxurious Masque Filler Réparateur after cleansing with the Première Concentré and Bain ritual. The rich, creamy texture melts into the hair, instantly transforming the feel of dry, coarse lengths into something silky, flexible, and utterly responsive. Leave it on for 5 to 10 minutes to allow the potent ingredients to work their architectural magic, then rinse to reveal strands that are 53% shinier and boast an incredible seven times more smoothness. This is more than just conditioning; it is an intensive, anti-breakage treatment that puts an end to the frustrating cycle of persistent damage, leaving you with hair that feels reborn and is resilient enough to hold onto those beautiful, healthy lengths.
