Windle & Moodie, explains that the formula for purple shampoo was devised according to the hair-color chart that has existed since the art of hair dyeing began. “Like paints or any color mixing, if you want to cancel out a tone, you use the opposite shade on the chart,” he expains. “So, purple hues help fight brassy, yellow tones while keeping the base color underneath lighter.”
