InStyle | The 9 Best Purple Shampoos of 2022 for Getting Rid of Brass on Blonde Hair featuring Phenix Founder and Celebrity Stylist Gina Rivera

While it’s still up for debate if blondes have more fun, one thing is true: maintaining a bright blonde color requires some extra TLC. No matter what type of blonde you are, you’re probably  fighting to keep your hair color from looking brassy, orange, or downright green (yikes!). Thankfully, a special breed of toning purple shampoo treatments exists to simplify all that blonde maintenance into just one weekly cleanse — and it’s the not-so-well-kept secret to keeping blonde hair bright and beautiful.

Because purple is the opposite of orange on the color wheel, dark purple pigments counteract the brass, which help cool and tone your hair color. All you have to do is lather up with a quarter-size dollop of shampoo and rinse it out. Just don’t leave it on for more than five minutes, or you might find yourself with a few purple-tinted highlights.

However, not all purple shampoos are created equal, so we’ve rounded up a few that we count on to keep our own heads of hair the perfect shade of blonde. Keep on reading to see our recommended choices, and get ready to kick some brass!
