The reconstructing hair mask Kérastase Resistance Masque Force Architecte with the Complex-Ciment-Cylan3 strengthens the hair fiber from the inside. The hair becomes more resistant. The vitalizing care mask strengthens the protective barrier of the hair fiber, protects it from external influences and is not weighing the hair down. It gives the hair extraordinary suppleness and shine. For slightly damaged hair. Technology of the Kérastase Resistance Masque Force Architecte Complex-Ciment-Cylan3: Three molecules against strongly structurally damaged hair = triple effect: The ingenious combination of three highly effective molecules represents another breakthrough in the research of Avancée L'Oréal. The focus was on three essential aspects: Structure Filling Cohesion Ingredients of The Kérastase Resistance Masque Force Architecte Intra-CylaneTM: This molecule works in a two-step way. Its formulation penetrates deep into the hair fiber and then reconnects the weakened or damaged structures. Pro-keratin: Keratin is an essential part of our hair. This molecule settles in the hair fiber and fills the weakened areas in a targeted manner. The hair matter is visibly built up and strengthened from the inside. Ceramides: Ceramides also occur naturally in our hair. They lie around the hair fiber like a protective sheath, preserving the strengthened structures inside the fiber and providing a velvety soft, shiny and perfectly protected appearance. Application of the Kérastase Resistance Masque Force Architecte Apply to the washed and towel-dry hair. Work into the hair lengths and tips, leave to act for 5 minutes and rinse thoroughly.
