If your hair is naturally blonde, color-treated blonde or gray, experts recommend adding a color-depositing shampoo to your hair care rotation to maintain your color. Color-depositing shampoos add specific pigments (either purple, blue or green) onto the hair shaft to maintain your desired color. Based on color theory, blondes should use purple shampoos, which is one type of color-depositing shampoo.
As the name suggests, purple shampoo uses violet pigments to tone and neutralize hair, allowing it to counteract unwanted brassiness and yellow/orange hues that can develop over time, according to Brittany Byrd, hairstylist and owner of Blondify Studio. These shampoos aren’t meant to cleanse or hydrate your hair nearly as much as regular shampoo, so these aren’t a complete replacement.
I spoke to four hairstylists and colorists and asked them about what ingredients to look for when shopping for a purple shampoo and how to find the right formula for your hair. I also asked them for their go-to formulas, along with our team of editors at NBC Select.

How I picked the best purple shampoos
To keep your hair toned and bright, whether it’s blonde, gray or white, experts recommend considering the following:
- Pigment: Purple-based pigments can neutralize yellow hair tones, which you’ll see when blonde hair oxidizes. When shopping, you may find shampoos in ranges of purple — from lavender to dark violets — since they have varying concentrations, according to hairstylist and salon owner Tiffany Munoz.
- Frequency: You can use lighter, less concentrated purple shampoos more frequently because there’s less risk of your hair turning purple, while dark, more pigmented formulas require less frequent usage since they are more concentrated, according to experts. Overusing these shampoos can dry out your hair or, in some cases, alter its color by darkening it or making it appear purple.
- Ingredients: Since purple shampoos can be drying, our experts recommend looking for formulas that have moisturizing ingredients like shea butter, hyaluronic acid, glycerin and panthenol.

This purple shampoo has a lighter color deposit (meaning it does’nt add a ton of purple pigment to the top of the hair shaft), is one of the most affordable options on this list. “It’s for somebody that wants the occasional maintenance without a huge investment,” says Byrd. Keep in mind that this shampoo might be drying, so use a conditioner in conjunction with it, according to Byrd.

It removes the brassiness, adds shine and helps the hair retain moisture using humectants like glycerin and emollients like sunflower sprout extract, according to the brand. If you want a shampoo that’s a bit more powerful, consider R+Co’s Bleu Blonded Brightening Shampoo, which is more moisturizing and has a darker violet pigment, according to Munoz.

This Redken shampoo comes recommended by Burnside, who uses it on her clients and sees positive results. It not only manages to maintain their desired blonde, but it also helps repair damage, strengthen hair and increase hair elasticity.

Many reviewers also recommend going in with another shampoo or conditioner after, to soften the hair and get a more in-depth cleanse of the hair and scalp.

This formula, which has a 4.6-star average rating from over 11,100 reviews on Amazon, also conditions the scalp and strengthens the hair. If you want to target the same concerns but in a less-pigmented formula that’s more suited for daily use, consider the brand’s light formula, which only has 50% of the violet pigment seen in the original.

Best silver-toned hair:Davines Alchemic Shampoo Silver
- Suitable for all hair types

Burnside recommends this Davines option, which is especially great for platinum blondes and cool, silver-toned hair. Reviewers say this shampoo lathers well when emulsified with water and leaves their gray hair brighter, shinier and less dry than other options.

Editor’s pick:Olaplex No. 4P Blonde Enhancer Toning Shampoo
- Suitable for all hair types
- Improves dullness
- Strengthens hair
- A little drying
In addition to her standard hair-washing routine, NBC Select editorial director Lauren Swanson uses this purple shampoo to tone her blonde hair. “This Olaplex one is gentle on my fine hair and still does a solid job of bringing the brassiness down,” she says. “I typically leave it on for a few minutes before rinsing, but on particularly brassy, yellow days, I’ll let it saturate for several minutes.” She also recommends following up with a second cleanse and a moisturizing conditioner to combat any dryness and thoroughly clean her hair.
Recommended frequency: two to three times a week or as needed | Scent: citrus
Best mask: Christophe Robin Baby Blonde Mask
- Rich, creamy consistency
- Conditions hair
- Doesn’t weigh down hair

Although this isn’t necessarily a shampoo, you can use this hair mask during every wash, according to Byrd. “It’s a conditioner, so it bathes your hair in nourishing [and] hydrating ingredients [to help] your blonde get some pampering,” she says. “It’s also great because it’s very sheer, so it’s hard to go overboard.”
Recommended frequency: as needed | Scent: n/a

How to shop for a purple shampoo
When shopping, the experts I spoke to recommend taking a product’s consistency and your hair type into account.
Ingredients
Look for hydrating ingredients to prevent your hair from drying out. Consider options with humectants like hyaluronic acid and emollients like shea butter because they can counteract the drying element of purple shampoos, according to Byrd.
Consistency
Generally, purple shampoos at salons tend to have a thick consistency, while drugstore options have a more liquid consistency, according to Byrd. “I actually tend to like those [liquid options] because clients don’t go as overboard with them,” she says. Runnier shampoos tend to distribute a lot easier, and they usually have less concentrated pigment, so there’s less chance for user error, says Byrd.
Hair type and texture
Unlike other shampoos and hair products, you have a little more flexibility when it comes to choosing a purple shampoo for your specific hair type and texture.
- Hair texture. If you have fine hair, your thinner strands may get too saturated by purple shampoo, so consider using a more lavender-like purple shampoo or diluting your shampoo if you have a darker, more pigmented option. Also, coarser, tighter cuticles tend not to hold on to as much purple, she says.
- Hair type. This doesn’t play as massive of a role when it comes to purple shampoos, says Byrd. However, if you have curly hair, you may want to consider a purple conditioner instead of a shampoo, because purple shampoos can strip moisture from your curls, says Byrd.
How often should you use purple shampoo?
There isn’t a specific formula for how often you should use purple shampoo because everyone’s hair is different, however, generally speaking you can use your purple shampoo every four to six washes, says Byrd.
If you initially feel really brassy, try a clarifying shampoo before reaching for a purple shampoo, says Byrd. This type of product uses the surfactants in the formula to reach into the hair and pull out any contamination that is causing it to look discolored.
If that doesn’t work, Munoz recommends asking yourself whether your hair looks yellow when styled (like a light bulb)? If so, you know it’s time to reach for a purple shampoo, says Munoz.
Experts recommend having a separate non-purple formula for normal wash days and only use a purple shampoo for when you need that toning element, according to experts.
What happens if you overuse purple shampoo?
Overusing a purple shampoo can cause or worsen damage and dryness, or it can turn your blonde hair darker or even purple. The latter happens because of the large amount of pigment in these products, which can build up over time and cause hair to look dull, according to Byrd. (Some warm undertones are essential to keep for shine and brightness, she says).
If your hair is drying out, make sure you use other hair care products, like a conditioner, leave-in or hair mask, to bring in moisture. If your hair is looking purple, use a clarifying shampoo and visit your hairstylist so they can remove the color.
What are other ways to maintain your blonde?
Other than using purple shampoo or conditioner, experts recommend investing in:
- A showerhead filter: No matter where you live, a filtered showerhead can help prevent microcontaminants, like metals, from getting in your hair, says Byrd. Metals like iron, calcium and magnesium can tint your hair and dull out its appearance over time, says Munoz. Just make sure to change your filter every three months since they tend to accumulate gunk, according to experts I spoke to.
- Clarifying shampoos: These help remove excess buildup, like dirt and product residue, from your hair and scalp. “It’s actually going to make the products that you use afterward more effective because they can penetrate deep down in your hair,” says Byrd.
