Kérastase creates Resistance Force Architecte to reinforces the hair fibre. Hair feels stronger from root to tip. Recherche AvancÉe L\'OrÉal identified 4 levels of hair fibre erosion and has created Ciment-Cylane3 Complex. For the fi rst time in Kérastase, Intra-Cylane, Pro-Keratin and Ceremide have been combined together in each step of the haircare routine. The formula is able to target high levels of erosion and provides intense condition to the hair, leaving it feeling replenished and stronger. Kérastase Bain Force Architecte Reconstructing Shampoo is Kérastase\'s first in-salon solution to fight high levels of hair erosion, for example, split ends and broken hair.
