The 10 Best Purple Shampoos for Brass-Free Hair (2026)
By Retail Verdict Editorial · Last Updated August 2026 · 12 min read
Finding the best purple shampoos can feel like a guessing game, especially when brassy undertones start creeping in just weeks after a salon appointment. Whether you’re maintaining an icy platinum, keeping silver strands luminous, or preserving expensive highlights, unwanted warmth has a way of showing up uninvited. Purple shampoo works by applying basicÂ
color theory – violet pigments sit opposite yellow on the color wheel, so they counteract golden and brassy tones on contact. The result is cooler, brighter-looking hair without a trip to the salon. We put dozens of formulas to the test to find the ones that actually deliver.

Pureology Strength Cure Blonde Shampoo & Conditioner | $72 Jump to ReviewBest Overall: Moroccanoil Blonde Perfecting Purple Shampoo
Moroccanoil
Blonde Perfecting Purple Shampoo
Why We Love It
- Delivers noticeable toning after just one wash without over-depositing pigment
- Argan-oil-infused formula leaves strands feeling conditioned, not stripped
- Signature Moroccanoil scent is subtle and pleasant
Worth Noting
- Premium price point compared to drugstore alternatives
This is the most well-rounded purple shampoo we tried. The formula balances toning power with genuine hair care – strands come out looking cooler and feeling silky rather than parched after rinsing. It lathers more than expected from a sulfate-free formula, making it easy to distribute from roots to ends. The argan oil base keeps mid-lengths hydrated, something rarely achieved with toning shampoos. The only downside is the price tag, which may give budget-conscious shoppers pause, but the results justify the cost over cheaper options that tend to dry hair out.
Recommended Use: 1-2 times per week | Scent: Warm amber and musk | Sulfate-Free: Yes | Size: 6.7 oz
Best Drugstore Purple Shampoo: Aussie Blonde Hydration Purple Shampoo
Aussie
Blonde Hydration Purple Shampoo
Why We Love It
- Genuinely effective toning at a fraction of prestige prices
- Lightweight texture rinses cleanly
Worth Noting
- Contains sulfates, so it may not suit very dry or chemically processed hair
For under ten dollars, this Aussie formula punches well above its weight. Worked into a lather and left on for three minutes, it made highlights look visibly brighter, with less of the golden muddiness that builds up between salon appointments. The lather is rich and easy to spread, and the shampoo rinses out without residue. Ends may feel slightly drier than usual – not surprising given the sulfate content – so pairing it with a good conditioner is non-negotiable. Still, for the price, it is hard to beat.
Recommended Use: 1-2 times per week | Scent: Fruity, tropical | Sulfate-Free: No | Size: 8 oz
Best Purple Shampoo for Gray Hair: Sachajuan Silver Shampoo
Sachajuan
Silver Shampoo
Why We Love It
- Gentle cleansing that respects curl pattern and moisture levels
- Mushroom and bamboo extracts strengthen color-treated strands
Worth Noting
- Toning effect is subtle – not ideal if you need heavy brass correction
Curly and coily textures need a toning shampoo that does its job without disrupting the moisture balance that keeps curls defined. This formula cleanses without that squeaky-clean feeling that usually signals stripped oils. Blonde highlights look fresher after each wash, and curl patterns stay intact – no extra frizz or dryness. The toning power is on the gentler side, which is actually preferable because it means zero risk of over-depositing. For anyone with textured, color-treated hair looking for a low-maintenance toning option, this belongs in your shower.
Recommended Use: 1-2 times per week | Scent: Light herbal | Sulfate-Free: Yes | Size: 8 oz
Best for Color-Treated Curly Hair: Briogeo Color Me Brilliant Shampoo
Briogeo
Color Me Brilliant Mushroom + Bamboo Color-Protect Shampoo
- Key ingredients: Aminexil, caffeine, arginine, ginger root extract, edelweiss
- Size: 3 fl oz (90 ml)
- Price: $64
- Where to buy: Kérastase, Sephora, Amazon
- Review signal: One of the brand’s longest-running bestsellers
Not all thinning begins at the follicle. If your hair is snapping mid-shaft from bleach, heat and a brush you use too enthusiastically, you don’t have a growth problem so much as a retention problem and this is the better tool for it. The jelly texture stays where you put it rather than running down your forehead, a small mercy among scalp treatments.
Worth knowing: Kérastase states plainly that Genesis is not a hair loss product, and its headline 97% figure applies to the full shampoo-conditioner-serum system rather than the serum alone. That candour is to the brand’s credit, but it also tells you who should skip it anyone whose part is genuinely widening rather than fraying. If heat is part of the story, our hair straightener testing is worth a look first.
Best for Brassy Hair: Redken Color Extend Blondage Shampoo
Redken
Color Extend Blondage Shampoo
Why We Love It
- Ultra-violet pigment deposits quickly and evenly
- Citric acid strengthens hair while toning
- Excellent lather and rinse
Worth Noting
- Can leave a slight violet tinge if left on beyond five minutes
If brassiness is your primary enemy, Redken’s Blondage formula brings serious toning muscle. Used twice a week for four weeks, it delivers a visible reduction in golden undertones by the end of the first week. The pigment distribution is even – no blotchy spots or uneven cooling – and the lather is satisfying and easy to work through thick, straight hair. One caveat: respect the clock. Leaving it on for seven minutes or longer can produce a faint purple cast at the temples. It fades after the next regular shampoo, but it is a reminder that more is not always better with highly pigmented formulas.
Recommended Use: 1-2 times per week | Scent: Subtle floral | Sulfate-Free: No | Size: 10.1 oz
Best for Bleached Hair: Fanola No Yellow Shampoo
Fanola
No Yellow Shampoo
Why We Love It
- Intensely pigmented – a small amount goes a long way
- Salon-grade strength at a moderate price
Worth Noting
- Can stain hands, nails, and shower surfaces if you are not careful
- Too potent for very porous or damaged ends without diluting
Fanola has a devoted following among professional colorists for a reason: this shampoo is intensely pigmented and works fast. A pea-sized amount is enough to tone an entire head in under three minutes. The formula neutralizes warm spots around the hairline and nape that always seem to resist salon toner. However, this is not a leave-it-and-forget-it product. The deep violet formula will stain your nails, your grout, and any towel it touches if you are not quick to rinse. For heavily bleached hair that needs serious correction between appointments, though, nothing else on this list matches its toning intensity.
Recommended Use: Once a week (or as needed) | Scent: Neutral, slightly chemical | Sulfate-Free: No | Size: 11.8 oz
Best Purple Shampoo for Shine: Amika Bust Your Brass Cool Blonde Shampoo
Amika
Bust Your Brass Cool Blonde Shampoo
Why We Love It
- Leaves hair with a noticeable glossy finish
- Sea buckthorn provides antioxidant protection for color longevity
- Rinses clean with no purple residue
Worth Noting
- Scent is polarizing – sweet and strong
If dull, lifeless blonde is your main complaint, Amika’s formula might be your answer. Hair has a visible sheen after the first use – not just brass correction but an actual glossy quality that lasts until the next wash. The sea buckthorn berry extract, an antioxidant-rich ingredient, helps protect color from environmental stressors like UV exposure and pollution. The scent is strong and on the sweeter side, which may not be everyone’s preference. Performance-wise, though, the toning is on point and hair never feels dry or crunchy afterward. For anyone who wants their blonde to not just look cooler but truly gleam, this is worth a spot in your rotation.
Recommended Use: 1-2 times per week | Scent: Sweet berry | Sulfate-Free: Yes | Size: 10 oz
Best Purple Shampoo for Highlights: Matrix Total Results So Silver Shampoo
Matrix
Total Results So Silver Shampoo
Why We Love It
- Evens out tone across highlights and base color without flattening dimension
- Cleans thoroughly without feeling harsh
Worth Noting
- Slightly drying on the ends – follow with conditioner
Highlighted hair presents a unique challenge for toning shampoos: you want the brass gone from the lighter pieces without affecting the depth of your natural base. Matrix So Silver handles that balance well. The purple tones target lighter strands without turning darker sections muddy. Highlights look cleaner and more distinct after three weeks of use. The ends, which tend to be the oldest and most processed sections, can feel a touch dry after each wash, so pairing this with a hydrating mask is recommended. If you are trying to keep your hair straighteners-smooth highlighted look on point between salon visits, this is a solid workhorse.
Recommended Use: 1-2 times per week | Scent: Light, clean | Sulfate-Free: No | Size: 10.1 oz
Best for Fine Hair: Verb Purple Shampoo
Verb
Purple Shampoo
Why We Love It
- Lightweight formula does not weigh down fine strands
- Tones gently without over-depositing
Worth Noting
- May need a longer leave-on time for heavier brassiness
Many purple shampoos feel thick and heavy, which is a problem if your hair is fine or flat-prone. This Verb formula feels almost like a regular shampoo in terms of texture. It lathers nicely, rinses completely, and leaves zero residue. The toning effect is gentle – a full five minutes of leave-on time is needed to see meaningful results – but that controlled approach is preferable to a heavily pigmented formula that could overpower delicate strands. Hair looks cooler without feeling limp or coated, which is a rare combination. If you have been searching for a toning shampoo that does not sacrifice volume, start here.
Recommended Use: 1-2 times per week | Scent: Mild citrus | Sulfate-Free: Yes | Size: 12 oz
Best Purple Shampoo and Conditioner Set: Pureology Strength Cure Blonde Shampoo & Conditioner
Pureology
Strength Cure Blonde Shampoo & Conditioner
Why We Love It
- Shampoo tones while conditioner replenishes – a complete system
- Vegan, sulfate-free, and 100% recycled packaging
- Both products feature a pleasant, spa-like fragrance
Worth Noting
- Highest price point on this list
Pairing a toning shampoo with a compatible conditioner makes the whole routine more effective, and Pureology’s Strength Cure Blonde set is the gold standard. The shampoo neutralizes warmth as well as any standalone pick on this list, and the conditioner follows up by adding back the moisture that toning can sometimes strip. After four weeks, bleached balayage looks cooler, feels stronger, and shows noticeably less breakage at the ends. The set is vegan and comes in recycled packaging – a plus for eco-conscious shoppers. The price is steep, but you are essentially buying two premium products in one. If you have been piecing together shampoo-conditioner combos from different lines, this eliminates the guesswork.
Recommended Use: 2-3 times per week | Scent: Floral, slightly minty | Sulfate-Free: Yes | Size: 9 oz each
What to Keep in Mind
Sulfate-Free vs. Sulfate Formulas
Sulfates are surfactants that create a rich lather and strip oil and buildup effectively, but they can also fade color-treated hair faster and leave strands feeling dry. If your priority is preserving your color investment, a sulfate-free purple shampoo is generally the safer choice. The trade-off is that sulfate-free formulas produce less lather and may not cut through heavy product buildup on their own. “Sulfate-free formulas are kinder to the cuticle, which means your toner lasts longer between appointments,” notes hair-care expert and colorist Renee Vasquez.
Nourishing Ingredients to Look For
Color-treated and bleached hair is more porous than virgin hair, so any shampoo you use regularly should contribute to its health, not just its tone. Look for formulas that include hydrating agents like argan oil, coconut oil, or hyaluronic acid, as well as proteins such as keratin or silk amino acids that help reinforce weakened strands. “You’re asking your hair to absorb pigment every time you wash with a purple shampoo, so giving it moisture and protein support in the same step is ideal,” says Vasquez. Our picks with the best conditioning profiles include Moroccanoil and Pureology, both of which left testers’ hair feeling noticeably softer.

How Often to Use Purple Shampoo (and Avoiding Over-Toning)
The most common mistake with purple shampoo is using it too often or leaving it on too long. Most formulas perform best when used once or twice a week, swapped in for your regular shampoo on those days. If you are new to toning shampoos, start with once a week and observe the results before increasing. Leaving a purple shampoo on for longer than the label suggests can deposit excess pigment, resulting in a noticeable violet or ashy cast – especially on lighter, more porous hair. If that happens, a clarifying shampoo will usually remove the unwanted tint within one or two washes.
Your Questions, Answered
How do you use purple shampoo?
Wet your hair thoroughly, then apply a small amount of purple shampoo and work it into a lather from roots to ends. Leave it on for the time specified on the label – typically two to five minutes. Rinse completely and follow with conditioner. If you are new to purple shampoo, try mixing it with your regular shampoo in a one-to-one ratio for a gentler introduction. Concentrate the product on areas where brassiness is most visible, and run it through the ends quickly since porous ends absorb pigment faster and can turn uneven.
What is the downside to purple shampoo?
The main risk is over-toning. If you use purple shampoo too frequently or leave it on too long, your hair can develop a purple or ashy cast that looks unnatural. The effect is temporary and washes out over a few shampoos, but it can be startling. Purple shampoo can also stain your hands, nails, shower tiles, and towels if you are not careful. Finally, keep in mind that purple shampoo provides a temporary tonal correction – it does not replace professional toning or color services.
Is blue or purple shampoo better for brassy hair?
It depends on your base tone. Purple shampoo neutralizes yellow and golden brassiness, making it the better choice for lighter blondes, platinum shades, and gray or silver hair. Blue shampoo targets orange brassiness and is more effective for darker blondes, light brunettes, and brunettes with warm undertones. If your brassiness pulls more gold, reach for purple. If it leans more copper or orange, blue is your match. When in doubt, consult your colorist – they can recommend the right pigment for your specific shade and level.
How often should you use purple shampoo?
Once or twice a week is the sweet spot for most people. Some heavily pigmented formulas, like Fanola No Yellow, may only need a single weekly application. Lighter formulas, like Verb Purple Shampoo, can be used more frequently without risk of over-toning. The right frequency depends on your hair’s porosity, your specific shade, and how quickly brassiness returns between uses. Start conservatively and increase if needed – it is much easier to add another session than to undo a purple cast.
