A long time!! I would try it because it's temporary but takes more than 4 months to completely come out. But it also depends on how much mixture (power stuff) you put into the water to effect the shade of the colour. and how long you dip the section your hair into the kool-aid
Depending on how long you heat your Kool-Aid mixture before you apply it on your hair, the dye could last for more than a month. Your new hair color can never be permanent, but it can last for several shampoos.
