Kérastase Resistance Bain Force Architecte is a daily shampoo designed for weak, damaged or brittle hair. With daily use, this product gently cleanses hair while strengthening and smoothing from root to tip, making it the perfect solution for thirsty, weakened hair that’s suffering as a result of heat styling or dying. Kérastase’s strengthening shampoo has been specially designed to clean, repair and fortify damaged hair at erosion levels 1-2, which is Kérastase’s scientifically formulated scale for analysing hair damage. With the active ingredients Vita-Ciment® - which contains Intra-Cylane, Ceramide R and Pro-Keratin - and Sève de Résurrection, this shampoo rebuilds hair from within, strengthening hair to prevent brittleness, split ends and breakage. Meanwhile, Kérastase’s innovative cleansing formulas effectively lift away dirt and impurities. Resistance Bain Force Architecte is designed for daily use. To effectively regenerate and reconstruct the hair, apply as you would your regular shampoo. Work the product evenly throughout the hair, massaging into the scalp and emulsifying into the lengths. Rinse thoroughly and style as normal to reveal noticeably smoother, stronger and rejuvenated hair.
