L’Oreal Professionnel Metal Detox Concentrated Oil is an innovative hair treatment oil which helps protect hair against copper particle deposits and unwanted breakage. With each wash, metal particles are naturally deposited onto the hair, penetrating the hair shaft which can lead to breakage, damage, and colour fade. This unique oil helps remove the build-up of copper, increasing hair resilience and strength whilst enhancing colour protection. Formulated using Glicoamine, the multi-benefit oil smoothes and cares for all hair types without weighing it down, whilst providing heat-protection up to 230°C. With continued use, hair breakage is reduced by up to 97% with up to 2x greater shine. Can be used on all hair types, but especially effective at treating colour-treated, damaged, and/or bleached hair. DIRECTIONS Apply daily onto towel-dried or dry hair, focusing on the mid-lengths and ends. Do not rinse out. Style using a hair dryer.
