As a longtime hair-bleacher who's had every shade of platinum blonde — silver, white, and even violet — I've had a lot of experience with using purple-hued toners to eliminate brassy and yellow undertones in my hair. Toners can be tricky to use on your own, however, which is why most pro colorists will recommend using a toning shampoo to banish brass. There are tons of different toning shampoos for different shades of blondes on the market, however — so if you're looking for one of the best purple shampoos for silver hair specifically, you'll want to stick with one of these tried-and-true options that I've rounded up below.
One of the most important things to know about toning your hair with a purple shampoo is that it all depends on how long you leave the shampoo on for. If you're just looking for a subtle bust of brassiness, a couple minutes should do — but if you're purposefully aiming for a more violet-hued shade of silver, you'll want to leave it for a few more.
Another important tip: Though most purple shampoos won't stain your shower, they can stain shower curtains — so be extra careful with application.
Ahead, find three of the best purple shampoos for platinum blonde hair. While you're at it, consider picking up one of the best hair masks for bleached hair, too. Not only will they amp up the silver even further, but they'll help soften and repair hair that's become damaged from all that bleach.
