How long does Manic Panic last?

Manic Panic lasts differently from person to person and from color to color. Lighter colors fade quickly, while darker colors last longer. As long as the dyed hair is well-maintained, the Manic Panic lasts four to six weeks. It should be applied and left on for at least an hour.

Traditional color-safe shampoos should not be used with Manic Panic, because it prevents the hair dye from processing properly. Manic Panic is a vegan semi-permanent hair dye. This means it does not contain any harmful ingredients that damage hair, such as animal byproducts. Dawn dish soap gradually fades the hair dye.
