HAIR TYPE: Damaged Hair / COLLECTION: Serie Expert / Wash after wash, the metal in the water penetrates the fibre. This is one of the major causes of hair breakage. But did you know that porous hair has a higher risk of breakage because it absorbs 2x as much water and therefore metal? Daily stresses such as chemical treatments, heating appliances and UV rays multiply the number of micro-cracks on the hair's surface and create cavities in the cortex. This makes the hair even more porous, which then absorbs an excessive amount of water and therefore metal, leading to a higher risk of hair breakage. Anti-porosity technology* to treat hair when it is most vulnerable to water: before shampooing. It is concentrated with 2% Glicofiller, an active ingredient that has a dual action on the surface and in the cortex, to prevent excessive absorption of water containing metal: - On the surface: it coats the fibre & fills 1 million micro-cracks in 1 minute*. - Inside the fibre: it penetrates deep & fills right up to the cortex. This new pre-shampoo is part of the Metal Detox range, a complete anti-metal protocol to prevent breakage & colour fading.
