The classic color theory is what purple shampoo is based on. When blondes deal with brassy tones, they want to cancel out yellow. And purple is the opposite of yellow.
Take a look at a color wheel and you will notice that purple and orange neutralize each other. Therefore, if you use purple shampoo, it should cancel out brassy, yellow tones.
However, can you use purple shampoo on brown hair is what most people wonder? The answer is yes, but don’t expect too much. It won’t be particularly effective on brown hair. If you have brown hair with highlights, the purple shampoo will lighten your highlights only. However, it won’t help you bounce back from brassiness if you have dark-colored hair.
There’s a special shampoo invented for dark-colored hair. It’s called ‘blue shampoo’. And makes a better choice for brunettes than purple shampoo. It gives better results.
Can Purple Shampoo Lighten Hair?
Excessive heat styling, UV rays, and even the minerals in the water can make your hair brassy. Purple shampoo can lighten hair but only blonde and highlights in dark-colored hair.
Brassiness represents the orange undertones that appear in colored hair over time. And since purple sits across from yellow on the color wheel, you can use it to neutralize yellow undertones.
If you’re a brunette with highlights, keep in mind that purple shampoo will lighten your highlights only. If you want a substitute for purple shampoo for dark hair, buy a blue shampoo.
