L'Oréal Paris Elvive Hyaluronic Pure Shampoo 400ml is a cleansing and hydrating shampoo developed for hair with oily roots and dry ends. Because it combines Salicylic Acid and Hyaluronic Acid, it helps restore balance from root to tip. Salicylic Acid is known for its purifying action. In fact, it works to remove excess oil and product buildup from the scalp. As a result, the hair feels fresher and looks cleaner for longer. Furthermore, this action helps extend the freshly washed effect for up to 72 hours. Meanwhile, Hyaluronic Acid delivers hydration where it is most needed.
