L'Oréal Professionnel Metal DX Anti-Deposit Protector Mask is an advanced hair treatment designed to protect colour-treated and lightened hair from metal particle deposits that can lead to breakage and impact colour results.
Powered by patented Glicoamine technology, this rich cream mask penetrates deep into the hair fibre to neutralize metal buildup caused by water exposure. It helps reduce porosity, intensely nourishes the hair, and restores softness and shine for healthier-looking lengths.
Ideal for use after colouring, balayage, or lightening services, the Metal DX Mask helps maintain vibrant, true-to-tone colour while strengthening the hair fibre against future damage.
