GUILT-FREE GLAMOUR!® Blue Panther® AMPLIFIED is a rich, deep violet-blue hair dye with cool blue/purple undertones. For best results, use this dark, velvety shade on pre-lightened hair! Please note that since Blue Panther® is so pigmented, it should work well on most hair levels but due to its blue undertone, it can clash with very orangey base tones on virgin, unbleached hair! Blue Panther® can also be added into lighter colors like Amethyst Ashes to punch up their vibrancy and staying power or over your natural brown hair for added depth and intensity! Also available in our Classic High Voltage Cream Formula!
