MANIC PANIC Atomic Turquoise is 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. The Amplified line of semi-permanent hair color dye lasts 30% longer than the MANIC PANIC High Voltage Classic hair dye collection, leaving your lovely locks with a vibrant color that lasts 6 to 8 weeks. Choose from a range of more than 20 colors that offer vivid, bold results for all hair types. All MANIC PANIC hair dyes are free from gluten, ammonia, PPD, resorcinol and phthalates, packed in a Vegan formula. Every MANIC PANIC hair dye is PETA accredited, made in the USA and tested on celebrities - not animals. For best results, pre-lightened hair to a level 9 or 10 using MANIC PANIC Flash Lightning Bleach Kits. Then, brighten your mane within minutes with this blue hair color for men and women from MANIC PANIC. Hair dye results do vary, though, based on base color, porosity and hair type. Avoid using on hair with more than 10% grey coverage and read instructions included with the products.
