The professional formula of Blacklight Violet Anti-Yellowing Conditioner is more powerful than the retail formula (250ml) for better toning control. This conditioner, specially designed for highlighted, bleached, white and natural blonde hair, eliminates yellow and brassy tones and revives dull strands for clean and vibrant-looking hair. Its unique formula, enriched with 11 amino acids and argan oil, moisturizes, strengthens the hair structure and repairs surface damage while prolonging the color’s longevity. Paraben-free.
