With impressive revitalising benefits, Kérastase’s pre-cleanse formula ensures your hair and scalp are thoroughly purified and refreshed. Designed to be used before shampooing, the pre-cleanse treatment works to lift away up to 96% more pollutants than shampoo ordinarily does, providing a deep clean that doesn’t strip away essential goodness and moisture. Boasting a rich texture, the sumptuous black gel provides a deeply sensory experience from start to finish. It’s blended with hydration superhero Hyaluronic Acid, which means you won’t have to worry about your mane lacking in moisture. Hair will feel silky soft and appear smooth and lustrous for longer, as Hyaluronic Acid firmly locks in the water your hair needs and reduces the risk of it escaping throughout the day. The hair cleanser is finished off with an uplifting fragrance made up of Light Woods, Tea Rose and Musk, which characterise the signature Chronologist scent.
