No matter the season, year, or decade, brassy hair is just not a look we can get behind.

Fret not if you're a salon blonde dealing with brass because there's a solution: purple shampoo.

Today we're doing a deep dive on the topic, explaining when and how to use purple shampoo and how this miracle product works. We're also showcasing the best purple shampoo formulas we offer. Keep scrolling for everything you need to know.

What does purple shampoo do to your hair?

Purple shampoo is responsible for keeping hair bright, cool, and brass-free. So, what does purple shampoo do, exactly? In a nutshell, the purple pigments in these shampoos counteract and neutralize the yellow and orange tones that pop up in blondes over time. Check out the color wheel, and you’ll see these two hues are opposites!

What are the benefits of using purple shampoo?

Incorporating a purple toning shampoo into your routine is beneficial for several reasons. The obvious advantage is less brass, which we outlined above. It also keeps your hair looking fresher and more like that “just walked out of the salon” color (you know that feeling!). This maximizes your last dye job and can help stretch appointments between in-salon toning, foiling, and balayaging. Of course, purple shampoos also clean your hair, and many boast other benefits such as strengthening, softening and boosting shine.

Who should use purple shampoo?

Blondes tend to have more visible brassiness in their hair compared to other hair colors simply because their hair is lighter. Still, you can also use blue or purple shampoo on brown hair to nix those unwanted orange and yellow undertones.

Additionally, you can benefit from using purple shampoo even if you have a warmer-leaning color, such as butter blonde or chestnut. We recommend using these products less frequently to strike the perfect balance of warm but not brassy.

Short answer: there’s a purple shampoo for blonde hair, brunettes, and the equivalent product for inky hair colors, too.

When should you not use purple shampoo?

As the saying goes, you can have everything in moderation, and the same applies when using purple shampoo. If your hair starts to look darker after using purple shampoo, that may be your cue to lay off the toning formula. That’s because overusing purple shampoo can also eliminate some of the yellow tones in strands that make them blonde, resulting in a color that appears visually darker.

Tips for Using Purple Shampoo

Read through these six pro tips to master the art of purple shampoo usage.

How often should I use purple shampoo?

If you want to keep your tresses as bright and shiny as possible, you may be tempted to use purple shampoo daily. Not so fast!

While purple shampoo for blonde hair is excellent at toning and keeping brass at bay, most brands recommend incorporating purple shampoo into your hair care routine once or twice a week. Those with warmer tones who want to nix brass without removing all their warmth should scale back to once or twice a month.

How long do you leave purple shampoo in?

Every product varies, so refer to the directions on the bottle and your desired brightness. However, as a rule of thumb, let it sit for three to 10 minutes.

Can I leave purple shampoo in overnight?

Purple shampoos contain toning pigments and chemicals that are intended to be left on your hair for a short time. According to the directions on the bottle, most purple shampoos should sit on your strands for only a few minutes before being rinsed out. Therefore, we don't recommend leaving any formula on your strands overnight.

Can purple shampoo damage your hair?

Purple shampoo shouldn’t damage your mane as long as you follow the instructions on the bottle.

Can you use purple shampoo on brown hair?

Yes, you can use purple shampoo on brown hair. The lighter your hair color, especially if you have highlights, the more difference you'll see before and after using a purple toning shampoo. However, those with all-over brown or highlighted hair will benefit more from using a blue shampoo, such as Redken Color Extend Brownlights Shampoo and Conditioner, a powerful toning system that assists in preventing and neutralizing brass for brunettes.

Do you need purple conditioner with purple shampoo?

It’s not a mandatory requirement, but we argue that some things are just better in pairs! Invest in a complete shampoo and conditioner system to maximize that brass-busting goodness.
