Hair colouring is a transformative experience—but hidden metals in water can cause colour to fade, dullness to set in, and breakage to occur. L’Oréal Metal Detox steps in to neutralise and remove these harmful impurities, leaving your hair stronger, glossier, and your colour truer for longer. This treatment isn’t just for coloured hair—it’s for anyone who wants hair that’s brilliantly healthy and free from hidden damage.
