The nourishing ingredients in the formula condition the hair during coloring and ensure a silky, shiny finish and a smooth hair feel. Dark Star is a very deep, slightly violet-grey hair tint. For optimum results, you should lighten your hair to blonde level 10 or lighter before use. Dark Star can also be used to dye your favorite Manic Panic shades darker to create a custom shade. Dark Star is also the perfect background shade for the popular prismatic rainbow hair effect or as an admixture for smoky versions of your favorite semi-permanent Manic Panic hair colors. Pastel & Gray shades contain less pigment than Manic Panic's vibrant shades and therefore fade faster.
