Addressing hair that suffers from the combination of oily roots and dry ends, the Kérastase Specifique Bain Divalent Shampoo Duo works to regulate excess sebum that causes greasy hair whilst repairing and deeply nourishing any areas from lengths to ends that are dry or damaged. Combatting oily roots starts by creating a healthy scalp environment. Greasiness here can be caused by an overabundance of sebum and the Vitamin B6 in this reparative shampoo helps zap excess oil by soothing the scalp and balancing the sebaceous glands. As nutrition is restored at the scalp and it is deeply cleansed and purified, lengths become healthier too. Further enriched with Glycine ® to nourish, hydrate and fortify the hair, the result is a more vibrant and fresh appearance. Softness and natural shine are recaptured along the hair fibre which in turn makes it more flexible and manageable. Committed to eliminating excess oil from the scalp whilst rejuvenating the ends, the shampoo should be used daily by applying to wet hair and massaging in to stimulate blood circulation at the scalp.
