Resistance Bain Force Architecte by Kérastase. A daily shampoo specially created to care for and repair damaged and/or weakened hair. This shampoo acts on the origin of erosion and damage, the pilitic fibre, exerting a reconstructive action, improving its tone and resistance and promoting a soft and luminous texture. Additionally, it creates a protective film on the fiber, keeping it protected from future damage. After its first use, the results are already evident: you will feel an ultra-soft touch, hair breakage will decrease during styling and you will see a totally renewed and intense shine.
