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.
