I would like to make a purple shampoo. Purple shampoo, or Purple Shampoo, is specifically designed to neutralize yellow-orange tones in hair using the principle of complementary colors. The shampoo itself has a deep purple color. Washing and leaving it on the hair helps neutralize orange tones, turn yellow hair grey, and also helps lock in the grey color to last longer on the hair without turning back to yellow-orange. I would like to know what type of colorant should be used to make this kind of shampoo? The shampoo color is as shown in the attached picture.
