Revive and repair weak, damaged and brittle hair with the Kérastase Resistance Bain Force Architecte Duo, a reparative shampoo that strengthens, restores and softens dull, fatigued hair that’s in poor condition. This cleansing shampoo has been specifically formulated to thoroughly clean the scalp of impurities and nourish the ends of hair that are damaged, have split ends and are showing signs of weakness. Enriched with the brand’s Vita-Ciment® complex it contains both Pro-Keratin and Ceramide which work together to rebuild and strengthen the hair fibre resulting in softer, more manageable locks. With its strong focus on reconstructing the texture of the hair, it’s also infused with Resurrection Sap which encourages regeneration with its deeply hydrating and nourishing properties. Weakened hair can feel fragile and is far more susceptible to breakage and split ends. Resistance Bain Force Architecte works to rebuild the hair fibre, in turn making hair feel firmer, less brittle and with more tone. Nourishing the hair in this way helps to restore natural shine that’s lost on damaged hair, resulting in softer, glossier locks that are easier to style and more resistant to future breakage.
