Blacklight Violet Shampoo's professional formula is more powerful than the retail formula (250ml) for better tone control. This shampoo, specifically designed for highlighted, bleached, white, and natural blonde hair, eliminates yellow and brassy tones and revives dull highlights for a clean and radiant look. Its unique formula, enriched with 11 amino acids and argan oil, moisturizes, strengthens hair structure, and repairs surface damage while prolonging color longevity. Sulfate, salt, and paraben-free.
