Refreshes and adds vibrancy to natural or colour treated hair.*This shampoo shields your new hue from damage with fade block technology, keeping your salon-quality colour lustrous and rich. It's a gentle non-colour depositing system that buffs up lackluster and brassy shades by trapping in colour with a protective net that locks in dye and keeps mineral deposits at bay. Move back your next colour appointment - your hair will stay vibrant and shiny (shampoo after shampoo after shampoo).
