Manic Panic hair color is rainbow-colored, semi-permanent hair dye with more than 30 shades. Manic Panic has three hair color lines: High Voltage Classic, Amplified and Dye Hard. Dye Hard is the most temporary, washing out after each use. High Voltage Classic and Amplified both fade slightly with each shampoo.
Manic Panic recommends bleaching hair to get the brightest results and offer a bleach kit called Flashlightning. The bleach is not for mixing with the dyes. A newer product, Manic Mixer/Pastelizer, works with the High Voltage Classic colors to make the shades pastel. ManicPanic.com provides examples, tutorials and coloring accessories to assist its customers.
