Manic Panic Lie Locks Classic High Voltage Semi Permanent Hair Color Cream is a cool, medium indigo purple-y blue hair dye. Lie Locks can add indigo hues to virgin, unbleached hair. For best results, we recommend lightening hair to a very light level 9 blonde and toning hair before use to prevent unwanted hues. The Classic High Voltage line of semi-permanent hair color conditioning creams from Manic Panic feature a range of over 50 colors that bring out bold, vivid looks for all hair types. This line of Vegan, semi-permanent hair color creams are free from parabens, gluten, ammonia, PPD, resorcinol and phthalates so you can feel good about changing up your look without any risks. Each one of our products is PETA accredited, made in the USA and tested on celebrities - not animals. And, this ready-to-use, no-mix blue hair dye fades gradually with each shampoo, lasting from 4 to 6 weeks. 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. Mark’s 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 don’t 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.
