Designed for hair with oily roots and dry, split ends, the Kérastase Specifique Bain Divalent Shampoo 250ml Duo has a formula that deeply purifies and cleans the scalp, while nourishing the dull, damaged strands. Thanks to its advanced formula and Salicylic Acid, it removes excess sebum and controls sebum production upon regular use. Taming the frizzy locks, this shampoo includes Glycine and Vitamin B6 that are essential for proper hair hydration. Its components lock moisture in and make sure that it is distributed throughout the fibre equally. Apart from rebalancing sebum and moisture, this rich shampoo nourishes the hair from within and leaves it shiny and smooth. Applied to wet hair, even the small amount creates a luxurious lather. It should be massaged into the scalp in light, circular movements to activate micro-circulation. Its fine texture doesn’t leave any residue when rinsed out, so the hair is voluminous and lightweight, as well as incredibly soft. Its Citric Acid and gentle perfume create a subtle fragrance that has an aromatherapeutic effect. Complementary to several Kérastase products, it is fit for daily use.
