L'Oréal Professionnel Serie Expert Metal DX Pre-Treatment Spray 500 m

L'Oréal Professionnel Paris Metal DX Pre-Treatment neutralizes metal particles thanks to the molecule Glicoamin in the hair fiber, which can otherwise lead to an increased risk of hair breakage and distorted color results. This treatment protects the hair before any coloring, bleaching, or balayage. As the formula penetrates deeply into the hair, hair breakage is reduced by 87%, and the color results become more even, longer-lasting, and shinier. Metal DX - the professional guarantee for your coloring, balayage, and bleaching, thanks to the 3-step application consisting of Pre-Treatment, Shampoo, and Care/Mask.
