Highlights, balayage, and ombre look incredible on brown hair—but lightening your brunette locks can lead to brassy tones over time. Hitting up the salon for a refresh every couple of weeks isn’t exactly feasible for all—so that’s where blue shampoo comes into play.

“Blue shampoo is a shampoo with blue pigments that cancels out unwanted orange, red, and copper tones in the hair,” says Alex Brown, a Chicago-based celebrity hairstylist. Calla Dawn, a senior colorist at Baja Studio in New York City, adds that blue shampoo works by coating the outside of the hair strand to minimize brassiness, much like a salon gloss.

Dawn explains that lightening your hair—whether via highlights or single-process color—exposes your hair’s underlying pigment. In most brunettes, that pigment is orange. That’s why your colorist will apply a gloss as a finishing touch. “A gloss not only adds shine, but it normally has pigment in it that tones down the warmth exposed after lightening the hair,” she says. After about a month of shampooing, heat styling, and being out in the sun, the gloss will fade, leaving behind the orange pigment underneath. Enter blue shampoo. “Using a blue shampoo is a great way to keep your hair looking cooler-toned between appointments,” says Dawn. (Dawn adds that purple shampoos and conditioners are a great option for blondes who feel like their hair is starting to look yellow.)

Here, we’ve rounded up the best blue shampoos for maintaining a beautiful brunette mane.
