Kool-Aid can be a safe, cheap option for experimenting with hair color, creating bright highlights, or dip-dyeing your tips. It can also be a pain to fade or rinse out of your hair.

Baking soda is the main ingredient that will help strip the color more quickly, whether dissolved into hot water for a soaking solution, or mixed with shampoo to form a paste.[1]
