Repairing Spray for Colored Hair L'Oreal Professionnel Metal Detox Pre-Treatment Spray

Metal accumulation within the hair fiber can create a risk of breakage and negatively affect the outcomes of dyeing, calibrating, and lightening processes. Excessive copper within the hair fiber can interfere with the oxidant. This means the oxidant may not perform its job properly. This patented technology, enriched with glycolamine, helps neutralize excess copper, ensuring it doesn't affect your color. As the formula penetrates the fiber, it yields uniform results, extends longevity, and leaves hair brilliantly shiny.
