An FAQ on purple shampoos and conditioners

Ahead, we dialed our team of haircare experts — a celebrity hairstylist specializing in blonde hair and a cosmetic chemist with more than 25 years in the hair loss space — to put together an all-in-one guide to shopping for purple shampoos and conditioners.

What are the benefits of purple shampoo?

As mentioned, purple shampoo is an at-home toning product recommended for those with blonde and gray hair or highlights. More closely, purple shampoos contain purple pigments that neutralize brassy, yellow tones. 

“Purple shampoo enhances the vibrancy of the hair color, whether natural or color-treated, and corrects a yellow tone,” Green highlights.

When used on a regular basis, purple shampoos and conditioners help maintain the desired color of your hair and reduce salon visits, too, per Thompson. “They also help tone down brassiness caused by sun or water, refreshes your color between salon appointments, add shine and improve hair appearance and offer customizable usage for a desired toning effect,” she adds.

How to properly use purple shampoo and conditioner, according to experts

Once a week in the shower, lather purple shampoo into wet hair. “Depending on the formula of your purple shampoo, it may be left on from one to 15 minutes before rinsing with water,” Green notes. “Leaving purple shampoo in your hair for longer than the time that’s recommended may cause hair to temporarily have a purple tint.”

Should a purple tint occur, it can easily be remedied by switching to regular shampoo until the purple pigment is removed. “It’s important to read the instructions on the bottle before using your purple shampoo to get the best results,” she advises. “After rinsing the purple shampoo from your hair, follow up with a hydrating conditioner.”

How often should purple shampoos and conditioners be used?

It’s important to note that the frequency of using purple shampoo will depend on your hair’s needs and the intensity of toning desired.

“Some people use it once a week, while others may use it more or less frequently,” Thompson says. “Experiment to find the right balance for your hair to maintain the desired color and avoid over-toning.”

How does purple shampoo compare to other types of shampoo?

“Purple shampoo is meant to correct brassy, yellow tones from blonde and gray hair,” Green explains. “Regular shampoo is designed to cleanse hair, removing any debris and excess oil.”

Purple shampoo does not replace regular shampoo. “Regular shampoos do not contain the crushed violet pigments, such as Acid Violet 43 and Ext. Violet 2, that are incorporated into purple shampoos, which is what gives purple shampoo the ability to cancel out brassiness,” Green shares.

How does purple shampoo compare to blue shampoo?

Yes, there is blue shampoo — and it’s important to understand its formula, uses and benefits while shopping for your purple shampoo (aka, its sister).

“Blue shampoos contain crushed blue pigments, rather than purple pigments, to correct brassiness,” Green explains. “Blue shampoo is better suited to correcting orange hues, while purple shampoo is better suited to correcting yellow hues.”

On the color wheel, yellow is opposite from purple and blue is opposite from orange, which is why they have the ability to neutralize each other as well.

For this reason, using a purple shampoo is recommended for blonde hair, specifically.

“Blonde hair is more susceptible to discoloration due to exposure to the sun, minerals in water, or product buildup. The purple pigments in purple shampoo work as color correctors, as purple is the opposite of yellow on the color wheel.”

Myths about using purple shampoo, debunked

Ahead, Thompson shares three myths about using purple shampoo for blonde hair and explains why they’re false (and, debunks all the myths):

  • Purple shampoo makes you blonder. While purple shampoo creates more balanced tones, this only works on previously lightened hair at a level 9 or 10. (Think inside of a banana 🍌): If your hair is the color of the banana peel, you can actually make your hair look deeper and that statement goes for all colors. If it is the color of the outside of the banana, opt for blue shampoo to remove warmer and orangey tones.
  • You can use purple shampoo every day. While you shouldn’t technically shampoo every day because it strips your hair’s natural oils, it’s not advised to go purple every day. Think about a car tint. If you put a purple tint on top of a tint and three more tints on top of that, you’ll have a super dark tint and hardly see inside the window. The same goes for purple shampoo. If you over-purple your hair will look dark and dull. It will lack shine because we can’t see through the cuticle due to the build-up of purple. 
  • Leaving purple shampoo on longer makes it brighter and won’t dry out: This is false, as overuse of purple shampoo or applying long periods of time will dry out your hair which, in turn, won’t look healthy. Yes, overdoing it on the purple will dry your hair out.
