If your blonde’s looking a little more “banana” than “buttery,” it might be time to reach for purple shampoo — the unsung hero of cool tones. What exactly does it do, and how can you use it without overdoing it? Here’s everything you need to know about this violet-tinted miracle for brighter, brass-free hair.
What is purple shampoo and how does it work?
If you’ve ever noticed your bright blonde or silver strands fading into a yellowish hue, purple shampoo is your secret weapon. This color-correcting product refreshes your tone, all thanks to basic color theory. On the color wheel, purple sits opposite yellow, meaning the two cancel each other out.
“Purple shampoo is made with violet pigments that counteract unwanted pigments, such as brassy yellow tones, that blonde, silver or gray hair naturally take on over time,” explains Gina Rivera, hair artist and founder of Phenix Salon Suites.
That’s why this toning shampoo is a must-have for maintaining cool-toned shades between salon visits. It doesn’t dye your hair purple — it simply deposits subtle pigments that balance warmth and brighten your overall color.
While blondes are the main users, it’s also helpful for gray, silver and even highlighted brunettes looking to tone down brassiness without a full recolor.
The main benefits of purple shampoo
Using purple shampoo regularly comes with a handful of perks beyond just brighter hair. Here are some of the possible benefits:
- It neutralizes brassiness: As Rebecca Johnston, owner and freelance hairdresser at Rebecca Johnston Hair, explains, “Purple shampoo helps neutralize yellow or brassy tones in the hair, leaving blonde shades looking fresher and brighter. It also enhances the overall vibrancy of blonde hair and can give a cleaner, more polished finish.”
- It boosts shine and brightness: When those yellow hues are toned down, light reflects better off your strands — giving hair that just-toned, salon-fresh gleam.
- It extends time between salon visits: By keeping your color looking new longer, purple shampoo saves you both time and money. Plus, it’s better for your hair’s health and the planet. In fact, sustainable hair care practices, like spacing out salon treatments and choosing eco-friendly formulas, can reduce waste and chemical
- It works for multiple shades: While blondes love it most, Rivera notes that darker hair with highlights and even silver or gray tones benefits, too. Purple shampoo helps maintain cool undertones in any hair type prone to warmth.
How often should you use purple shampoo?
The trick with purple shampoo is moderation. Use it too little, and brassiness will creep back in. Use it too often, and you might find your hair turning slightly purple.
“Purple shampoo can be very strong, so it’s best to use it once a week or once every two weeks, depending on how your hair reacts,” advises Johnston. “You can also mix normal shampoo with purple shampoo to reduce the intensity.”
Rivera agrees, adding that how often you use it depends on your color. “To maintain blonde, I recommend using a purple shampoo at least two to three times a week,” she says. “Gray [and sliver] hair I recommend using at least once a week.”
If you’re new to purple shampoo, start slow — maybe once a week — and adjust based on your hair’s response. Over time, you’ll find the perfect rhythm for keeping your color bright without any lavender surprises.
How to use purple shampoo the right way
Using purple shampoo correctly makes all the difference between polished, brass-free hair and unexpected purple streaks. Here’s a simple step-by-step routine:
- Wet your hair thoroughly: Warm water opens the cuticle and helps the pigment penetrate evenly.
- Apply purple shampoo evenly: Start with a small amount and work it through your hair.
- Leave it on: As Rivera explains, “It’s good to leave your purple shampoo on the hair anywhere from three to five minutes. If washed out too early it won’t give it time to work.”
- Rinse thoroughly: Make sure no residue remains.
- Follow up with conditioner: Purple shampoo can dry out your hair, so a hydrating conditioner is key.
Johnston adds a precaution for salon-goers: “If you’re due to have your hair colored at a salon, I’d stop using purple shampoo about two weeks before your appointment. It might lead to your hair appearing dull and having to bleach it out, which can damage your hair.”

Common mistakes to avoid
Even the best purple shampoo won’t help if you’re making some common mistakes. Avoid these pitfalls:
- Overusing it: Too frequent application can leave a purple tint.
- Leaving it in too long: Extended exposure can cause uneven color.
- Skipping conditioner: Purple shampoo can dry out your hair, so be sure to use a hydrating conditioner.
- Using the wrong strength: If your formula is too strong, mix it with regular shampoo to reduce intensity.
Purple shampoo myths, busted
Some misconceptions about purple shampoo might give you pause, but there’s no need for worry:
- It’s only for blondes: It works on gray, silver and highlighted hair, too.
- It replaces your regular shampoo: It’s a toning supplement, not a full replacement.
- More purple means better results: Definitely not. Balance is key — too much pigment can backfire.
The violet verdict
Purple shampoo is a simple, effective way to keep your blonde, gray, silver or highlighted hair looking fresh and polished. By neutralizing brassiness, boosting shine and extending the life of your salon color, it earns its spot in any hair care routine. With a little violet power in your routine, you’ll tone down the brass and turn up the brilliance.
