GUILT-FREE GLAMOUR!®Red Passion is a lovely, medium red hair dye with hints of pink. This cherry red shade glows under blacklight. We recommend lightening hair to a very light level 9 blonde before use. If your hair is brassy when Red Passion is applied,the end result can be a pink-orange tint; avoid this by using Silver Stiletto or Virgin Snow White Toner to remove brassiness before applying Red Passion.
