MANIC PANIC Purple Haze Amplified Semi Permanent Hair Dye is a warm, very dark purple hair color that leaves purple tones on virgin, unbleached hair. For best results, we recommend lightening hair to medium level 7 blonde or lighter before use. 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. MANIC PANIC originated in 1977 as one of the first products sold at the Bespoke Boutique on St. Marks Place in NYC. The vivid shades, tints and hues stemmed from punk rock pioneers Tish and Snooky Bellomo, who transformed the beauty brand into a leading hair color revolution still going strong 40 years later. Tish and Snooky dont just sell MANIC PANIC hair dye, they live it as they continue to perform regularly and showcase their vivid hair color on stage with legendary rock and roll acts. The New York native sisters, dubbed as the Martha Stewarts of Punk Rock believe in not only sharing colorful hair dye shades but also sharing a portion of their profits by donating 15% of MANIC PANICs annual profits to various charities.
