Perfect for damaged to very damaged hair, L'Oreal Professionnel Absolut Repair Lipidium Shampoo is an instant reconstructing shampoo that has been inspired by skincare treatments. Like skin, hair is made of different layers, that can suffer from lipid-deficiency. Loss of lipids are caused by chemicals, heat styling and external aggressors including sun, salt and chlorinated water. Lipid-deficient means hair may break easily, styling will become difficult, coloured hair will fade and textured hair will lose its bounce. So What is Lipidium? Lipidium is made up of Latic Acid that helps with cortex reconstruction, Phyto-Keratin and Ceramides that works to structure hair and Lipids that form a barrier film on hair to lock in actives and essential nutrients, which coats hair against new aggressors. This technological breakthrough shampoo contains the most reconstructing ingredients to replenish all hair zones and create an insulating barrier to lock in essential nutrients to restore healthy tresses.
