What is purple shampoo?

Purple shampoo is responsible for keeping hair bright, cool, and brass-free. Soo…what does purple shampoo do exactly? In a nutshell, the purple pigments found 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 benefit 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, in turn, 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?

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

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

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

Tips For Using Purple Shampoo

To master the art of purple shampoo usage, read through these six pro tips.

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 every day. Not so fast!

While purple shampoo 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 you can let it set for three to 10 minutes.

Can I leave purple shampoo in overnight?

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

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—and especially if you have highlights—the more of a 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! To maximize that brass-busting goodness, invest in a complete shampoo and conditioner system.
