Metal in water, penetrating inside your hair wash after wash, is one of the major causes of hair breakage.But did you know that porous hair has even higher risk of breaking as it absorbs more water with metal?Through daily aggressions like chemical processing, heat styling or UV, micro-breaks multiply on the hair surface & cavities occur in the cortex, causing hair to get porous & absorb excess water with metal. Micro-breaks are a disruption of the protective cuticle layer which are the first signs of damage. This leads to higher risks of breakage.Anti-porosity¹ technology to treat hair when it is the most vulnerable to water: before the shampoo.It is concentrated with 2% Glicofiller, an active that has a dual effect both on surface & cortex, to prevent excess absorption of water with metal:On the surface: it coats the fibre & refills 1 million hair micro-breaks, in 1 use².Inside the fibre: it penetrates the hair & fills down to the cortex.This new pre-shampoo treatment is part of the Metal Detox range, a full anti-metal protocol to help prevent hair breakage & colour fade, providing up to 99% less breakage³ when the full range is used.Deep penetration with long-lasting efficacy.
