The Kérastase Première Shampoo Refill seeks to clarify damaged hair to promote a stronger, fresher feeling. Arriving in a refill pouch, the shampoo replenishes your existing reusable shampoo bottle. Working against calcium found in your shower water, the formula helps to rinse away build-up that can cause further potential weakness and breakage. Harnessing the cleansing powers of citric acid, the lather sloughs away impurities and excess oils for a revitalised effect. Amino acid glycine enhances the formula to reduce the appearance of dryness.
