A refill for your existing aluminium shampoo bottle, the Kérastase Bain Hydra-Fortifiant Pouch works to gently purify hair and remove build-up on the scalp. Made with 82% less plastic*, the refill pouch is kind to both hair and the environment. The anti-fall formula helps to minimise the risk of breakages, encouraging fuller and healthier-looking hair. Antioxidant-rich ginger root and edelweiss native cells, known for their resilience, work in synergy to protect against pollution and other daily aggressors. Ideal for those with weak, breakage-prone hair, the shampoo helps to create a healthy scalp environment for hair growth. *vs two Kérastase 250ml shampoo bottles.
