Kérastase Bain Force Architecte Strengthening Shampoo Duo - 2 x 250 ml

Kérastase Bain Force Architecte duo (2 x 250 ml) rebuilds and strengthens the hair fibre at all levels of erosion. Its improved formula smooths and protects the hair surface while reconstructing the fibre to intensify strength from root to tip. Enriched with Complex Ciment‑Cylane (3) for visible fibre reinforcement. To use: apply a small amount to wet hair and scalp, massage with the palms to emulsify, then rinse thoroughly. For best results, follow with Kérastase Ciment Anti-Usure or Masque Force Architecte, and use Fibre Architecte serum as a leave-in protectant. Kérastase is committed to more sustainable packaging—using less virgin plastic, increasing recycled materials, recyclable and refillable options—and to greener production: since 2019 the Burgos factory has achieved carbon neutrality and, since 2017, operates a closed-loop water recycling system.
