Kerastase Résistance Bain Force Architecte Reconstructing Shampoo

Kérastase Résistance Bain Force Architecte is a reconstructing shampoo in an 8.5 oz (250 ml) bottle, formulated for damaged and weakened hair. The distinction from a nourishing shampoo matters: nourishing formulas soften and smooth, whereas this is designed to work on the hair's internal structure, reinforcing the fibre from within so hair becomes measurably stronger and less prone to breakage and split ends — which is what damaged hair actually needs. That makes it the right choice if your hair is snapping mid-length, feeling weak and stretchy when wet, or breaking after bleaching, colouring or repeated heat styling. It cleanses gently with a mild base that does not strip the hair further, and it lathers well and rinses clean without weighing hair down. Hair feels stronger, denser and more resilient over consistent use rather than only smoother on the day. Apply to wet hair, massage through scalp and lengths, then rinse thoroughly. Follow with the matching Résistance conditioner or masque for best results.
