I need a brand of dye or color that will temporaryly change dark hair color. I plan on dressing myson up for otakon again this year, i know he wont tolerate a wig so i was thinking of some sort of hair color that will last the day then wash right out during bath time. He'll be two and a half by then and i need to change his black/dark brown hair to white, medium brown, and pink
