A purple toning shampoo that strengthens, hydrates, and neutralizes brassiness while keeping hair hydrated from roots to ends. Suitable for fine, medium, and thick hair with coily, curly, straight, and wavy textures. It addresses brassiness, color fading, and is color safe. Contains Bis-Aminopropyl Diglycol Dimaleate to rebuild broken and weakened bonds. This concentrated, sulfate-free formula is vegan, gluten-free, and cruelty-free. It boosts blondes three times brighter compared to top purple shampoos and has a light, clean, subtly sweet citrus scent with grapefruit and mint notes. Use as needed to brighten brassiness, applying to wet hair and leaving for 1-3 minutes, up to 5 minutes for more intense toning. Follow with Olaplex conditioners for moisture and repair.
