The Kerastase Resistance Masque Extentioniste is a length-strengthening mask designed for slow-growing, damaged lengths. Formulated with Creatine, an amino acid that penetrates deep to reinforce the hair fiber, it also blends Ceramide to deliver surface recovery for visibly healthier hair. Infused with Maleic Acid to strengthen and seal the cuticle with a uniform coating from root to ends. This treatment repairs bonds within the hair structure while improving overall strength and elasticity. Hair appears softer, smoother, detangled, and more manageable.
