Originally called "Fruit Smack," Kool Aid was invented in the late 1920s, though it wasn't until the 1990s that the soft drink mix gained popularity as hair dye. A cheap yet effective temporary hair dye, using the stuff on wigs works well, as wigs do not require regular shampooing like the hair on your head. Use pink Kool Aid to dye wigs for costumes, theatrical and video productions or to simply change your hairstyle.
Mix pink, sugar-free Kool Aid with white or other light-colored conditioner in a small to medium-sized bowl. Use sugar-free Kool Aid to avoid making the wig sticky. The amount of conditioner and Kool Aid you will require depends on how much hair the wig contains.
Place the wig on a wig stand over a sink, tub, newspaper or other applicable surface. Put on a pair of rubber or latex gloves and pick up the dye with your hands to apply it to the wig. Start from the crown of the wig and work your way down in even strokes until you have covered the entire wig with dye. Work with one 1- to 2-inch section at a time for best results.
Place a shower cap over the wig and leave the Kool Aid dye on overnight. Leave the dye on blonde wigs for eight hours; dark-colored wigs should have the dye left on for about 12 hours.
Rinse the wig with water to remove the excess dye and conditioner. Do not shampoo the wig, which will rinse most if not all of the dye out.
