Avoid using on hair with more than 10% grey coverage 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 strong 40 years later. 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 Panic's annual profits to various charities.
