Hairstylist Jennifer Korab agrees, adding, "As the weeks progress, it’s common for color-treated hair to become brassy regardless of color tone. Blue shampoo can counterbalance the brassy pigment and extend the life of the hair between salon visits." Made specifically for lightened brunette hair, this sulfate-free shampoo deposits blue-violet pigments to reduce brassiness and counteract unwanted warm tones.

Won't that turn my hair blue, we hear you ask? Not quite, as the process is a little bit more scientific than that. How does blue shampoo for brown hair work? For years, purple shampoo has been the anti-brassiness poster child when it comes to minimizing those inevitable, unwanted warm tones that occur slowly but surely in lightened strands. (In case you're curious, frequent washes, sun exposure, heat-styling, and the minerals and chemicals found in our water can be held responsible.) Alas, to keep lightened hair looking as fresh, cool, and un-yellow as possible, purple can save the day. Since purple shades are best at canceling out yellow tones, those violet-hued shampoos are typically more effective for people with blonde or gray strands, and—plot twist— blue-toned shampoos are actually the far more strategic choice if you have brown hair, be it a dye job or your au naturel hue.

So, how do you know it's time to break out the blue shampoo? "If someone struggles with fading to an unwanted yellow/orange brassy tone midway point between visits to the salon, they are a good candidate for blue shampoo," Wiley says.

Frequency of Use: Most blue shampoos are intended to be used two or three times a week, which is the case with Not Your Mother's Triple Threat Brunette Blue Treatment Shampoo, though weekly use is often plenty. Be sure to read the directions carefully to avoid overusing it, as the blue pigments could leave your hair with a purple tint. "Sometimes purple or blue toning shampoos can over-tone and cause the hair to look dingy," adds celebrity hair colorist Guy Tang. Just like skin, your hair gets its natural color from melanin — without it, your hair would be white. When melanin production starts to slow down, you may start seeing gray hairs.While there are many standout blue 'poos on the market, Matrix Brass Off shines above the rest.

"Blue shampoo should be used on brunette hair that has been lightened or highlighted by applying blue tone pigment into the hair to help tone down brassy tones," she instructs. "For virgin hair or slightly processed hair, it is beneficial to use once a week to make hair appear healthier and shinier and keep brassy tones from coming through."
