People with dark to medium brown hair who have previously lightened hair through any element of hair lightening, whether that’s highlights, balayage, all-over lightened, or permanent color to expose brassy tones. Finally, you also want to make sure the product does not strip your hair. Third, you want to look for a shampoo that guarantees the integrity of your hair and keeps the strength and moisture in your hair. The second is to ensure the product is not drying to the hair. The most important thing is that the product is pigmented enough to neutralize all the unwanted brass tones. It’s formulated to counterbalance the coppery tones in your hair and leave you with a more cool-toned finish. “Blue and orange are complementary colors on the color wheel, meaning the blue pigment in the shampoo neutralizes the warm underlying tones exposed on pre-lightened brown hair.” Below, Korab answers all our blue shampoo questions and picks her favorite blue shampoos on the market.

You know that orange-toned color that makes a brunette feel like a pumpkin? Yup, that’s brass. Brassy hair got you down? If you’ve ever bleached your strands or had any form of highlights, chances are you’ve been met with the fear of brassy hair.
