Oligo Blacklight Blonde Science NEU:VIO Hand Sanitizers Improves every aspect of badlyOligo Blacklight Blonde Science NEU: VIO is a professional violet neutralizing treatment from the Blacklight Blonde Science system. It counteracts yellow and gold tones in lightened hair. Use after lifting when the underlying warmth is in the pale yellow range. The violet pigment cancels unwanted warmth and sets the stage for a clean, neutral, or cool toned toner result.
