Oligo Blacklight Purple Shampoo is designed to neutralize yellow and brassy tones in highlighted, blonde, or white hair. Its formula, enriched with 11 amino acids and argan oil, hydrates, strengthens, and repairs the hair's surface while prolonging color. Apply to wet hair, massage, and leave on for 1 to 5 minutes before rinsing. Free of sulfates, salt, and parabens, it respects the hair fiber and is suitable for sensitive scalps. Use it as soon as unwanted tones reappear to maintain a vibrant blonde.
