Atomic turquoise hair dye: A bright, radiant aqua blue hair dye with green undertones. This color can add turquoise tones to virgin, unbleached hair, but looks brightest when hair is lightened to the lightest level 10 blonde. We recommend toning hair that has yellow tones before use to avoid undesired hues. Mixable colors and tones: All Manic Panic hair colors are safe to mix to create custom shades, making the possibilities of shades endless! Combine any formula with the manic mixer/pastel-izer to create soft, on-trend pastel hues. Ready to use, no developer required. Semi permanent hair dye: This semi permanent hair dye formula gradually fades in 4-6 weeks because it does not penetrate the cortex of your hair, but simply rests on top of the hair shaft. Cruelty free, vegan formula: This color cream hair dye features vegan ingredients tested on celebrities, not animals. Made in the USA, hair color is PPD & ammonia-free, paraben-free, gluten-free resorcinol-free, phthalate-free and PETA accredited. For best results: Vibrant color results are best achieved by applying to hair that has been pre-lightened with Manic Panic Flash Lightning Bleach Kits. Bleaching thoroughly to a level 9 or 10 before dyeing is recommended for the best results.
