This shampoo and conditioner duo needs no introduction. An absolute hair care staple for hairstylists and celebrities alike, Kérastase Resistance Bain Force Architecte 250ml Duo provides the very best care for even the most damaged locks and split ends. Perhaps your hair is damaged from over-styling, too much heat or repeated colouring. Whatever the cause of your damaged locks, look no further than Kérastase's most popular hair care line.

The Bain Force Architecte duo brings together a powerful combination of salon-quality ingredients and haircare expertise to help rebuild and strengthen hair from within. Tackling all levels of hair erosion, it helps to reconstruct dry, brittle and damaged strands. Proteins and glucose within the shampoo are designed to intensify existing strength while promoting healthy hair growth, shine and bounce. Patented Intra-Cylane acts as a ‘glue’ to reverse hair breakage and seal split ends for visibly improved lengths, while the conditioner’s silky-smooth formula helps to protect the surface of the hair from free radicals and pollutants that can cause damage over time. Use daily by applying to wet hair before lathering and rinsing.
