Brassy tones can turn beautiful brunette hair into an unwanted orange or yellow mess. This happens because brown hair color contains red and orange pigments that become exposed over time. Washing, sun exposure, heat styling, and even hard water can strip away the cool tones in your hair. What you’re left with are those warm, brassy undertones that make your hair color look dull and faded.
You don’t need to live with brassy hair or rush back to the salon every few weeks. There are simple methods you can use at home to maintain that rich, cool-toned brunette you want. Some solutions work immediately while others prevent brassiness from developing in the first place. The key is understanding what causes those unwanted warm tones and how to neutralize them effectively.
Below some practical ways to remove brassy tones and keep your brunette hair looking fresh and vibrant. These methods range from quick fixes to long-term care strategies. You’ll learn which products work best, how to adjust your hair care routine, and what to avoid if you want to maintain that deep, rich brown color.
Use Purple or Blue Shampoo
Purple and blue shampoos aren’t just for blondes anymore. These color-correcting products work on brunette hair too, though you need to pick the right one based on your specific brassiness.
Understanding Color Theory
Colors opposite each other on the color wheel cancel each other out. Purple neutralizes yellow tones while blue cancels orange. Look at your hair in natural light. If it appears yellowish, reach for purple shampoo. If it looks orange or coppery, blue shampoo is your answer.
How to Use Color-Correcting Shampoo
Wet your hair thoroughly before applying the shampoo. Work it through from roots to ends and let it sit for 3-5 minutes. The longer you leave it on, the more intense the toning effect. Start with less time and increase gradually to avoid over-toning.
Don’t use these shampoos every day. Two to three times per week is enough for most brunettes. Overuse can make your hair look dull or even slightly purple-tinted.
What to Expect
Your first wash might not show dramatic results. Color-correcting shampoos work gradually. After a few uses, you’ll notice your hair looks cooler and less brassy. The warm undertones become less obvious, and your brunette shade appears richer.
Some formulas are more pigmented than others. Professional brands tend to be stronger than drugstore versions. Start with a gentler formula if you’re new to toning shampoos. You can always switch to something stronger if needed.
Apply a Toner Treatment
Toner treatments provide more intensive correction than shampoo alone. These products deposit cool pigments directly onto your hair shaft to neutralize unwanted warmth.
Choosing the Right Toner
Professional toners come in various shades designed specifically for brunettes. Ash tones work well for most brown hair colors. Look for products labeled “cool brown,” “ash brown,” or “neutral brown.” Avoid anything with golden or warm in the name.
Demi-permanent toners last longer than temporary options but don’t damage hair like permanent color. They gradually fade over several weeks, which means you’ll need to reapply periodically. Semi-permanent options wash out faster but are gentler on your hair.
Application Process
Clean, damp hair absorbs toner best. Apply the product evenly from roots to ends using gloved hands or an applicator brush. Make sure every section gets covered or you’ll end up with uneven results.
Processing time varies by product, typically ranging from 10 to 30 minutes. Check the instructions carefully. Leaving toner on too long can make your hair look ashy or muddy. Set a timer so you don’t forget.
Rinse thoroughly with cool water until it runs clear. Follow up with a moisturizing conditioner. Here are the main benefits of regular toner treatments:
Longer-Lasting Results: Toners maintain cool tones for several weeks between applications.
Professional-Looking Color: Your hair looks freshly colored even as it grows out.
Customizable Intensity: You control how cool or neutral your brown appears by adjusting processing time.
Rinse with Cool Water
Hot water opens your hair cuticles and allows color molecules to escape. This simple habit change makes a real difference in maintaining your brunette shade.
The Science Behind Temperature
Your hair cuticle is like a protective layer of overlapping scales. Hot water lifts these scales, making your hair more porous. Color molecules slip out through the gaps, and brassiness shows through. Cool water keeps cuticles closed and color locked inside.
Making the Switch
You don’t need to suffer through cold showers. Wash and condition your hair with warm water if you prefer. Then turn the temperature down for the final rinse. Even lukewarm water helps seal the cuticle better than hot.
This final cool rinse also adds shine. Closed cuticles reflect light better than raised ones. Your hair looks glossier and feels smoother after just one wash with cooler water.
Additional Benefits
Cool rinses reduce frizz and improve hair texture. Your strands lie flatter and tangle less. You’ll notice your hair feels silkier when you skip the hot water.
Hard water contributes to brassiness by depositing minerals on your hair. Cool water doesn’t solve this problem entirely, but it does minimize damage. Consider installing a shower filter if you live in an area with hard water.
The change might feel uncomfortable at first. Start by gradually decreasing the temperature over several washes. Your scalp will adjust, and the benefits to your hair color are worth the brief discomfort.
Limit Heat Styling
Heat styling tools cook the color right out of your hair. High temperatures break down pigment molecules and expose those brassy undertones you’re trying to avoid.
Flat irons, curling wands, and blow dryers all cause damage when used frequently. The higher the heat setting, the faster your color fades. Even heat-protective products can’t completely shield your hair from thermal damage.
Finding Alternatives
Air drying is the gentlest option for your hair. Towel-dry excess water and let your hair dry naturally. This takes longer but preserves color much better than heat styling.
Try heatless styling methods like braiding damp hair for waves or using foam rollers for curls. These techniques create beautiful styles without any thermal damage. You can achieve most looks without plugging in a single tool.
When You Must Use Heat
Sometimes heat styling is unavoidable. Always apply a heat protectant spray or cream before using hot tools. These products create a barrier between your hair and the heat source.
Keep your tools on the lowest effective temperature. You don’t need maximum heat for most styling tasks. Test lower settings to find what works for your hair type.
Reducing Frequency
Cut back gradually if you currently heat style daily. Try limiting hot tools to special occasions or weekends. Give your hair break days where you use no heat at all. Here’s what happens when you reduce heat styling:
Color Stays Vibrant: Less heat means less color fade and fewer brassy tones developing.
Healthier Hair Texture: Your hair becomes stronger and more resilient over time.
Reduced Maintenance: You spend less time styling and more time enjoying naturally beautiful hair.
Deep Condition Regularly
Dry, damaged hair turns brassy faster than healthy hair. Deep conditioning treatments repair damage and create a smooth surface that holds color better.
Why Moisture Matters
Porous hair grabs onto environmental pollutants and minerals from water. These deposits create a dull, brassy appearance. Well-moisturized hair has closed cuticles that resist this buildup.
Color-treated hair needs extra hydration because the coloring process removes natural oils. Your hair becomes drier and more vulnerable to brassiness. Deep conditioning replaces lost moisture and strengthens your strands.
Choosing the Right Treatment
Look for deep conditioners with proteins and moisturizing ingredients like argan oil, shea butter, or keratin. Avoid products with sulfates or harsh chemicals that strip color.
Masks specifically formulated for color-treated hair work best. These contain ingredients that help lock in pigment while hydrating your strands. Check the label for color-safe or color-protecting claims.
Application Techniques
Apply deep conditioner to clean, damp hair. Focus on mid-lengths and ends where damage is worst. Avoid the scalp unless your product specifically says to apply there.
Leave the treatment on for at least 15 minutes. Some masks work better with heat, so consider wrapping your hair in a warm towel or using a heat cap. The warmth helps ingredients penetrate deeper into your hair shaft.
Use deep conditioning treatments once or twice weekly depending on your hair’s condition. More damaged hair needs more frequent treatments. Pay attention to how your hair feels and looks to determine the right frequency.
Rinse thoroughly but gently. Any residue left behind can make your hair look greasy or weigh it down.
Use Color-Depositing Products
Color-depositing conditioners and masks add pigment to your hair with every use. These products gradually build up cool tones while conditioning your strands.
How They Work
These treatments contain small amounts of semi-permanent dye mixed with conditioning ingredients. The pigments attach to your hair shaft and neutralize brassiness. Unlike regular dye, they don’t use harsh chemicals or require mixing.
The color deposits are subtle and cumulative. Each application adds a bit more pigment. You control the intensity by how often you use the product.
Selecting Your Shade
Pick a color slightly cooler than your current hair color. If you have medium brown hair with brassy tones, choose an ash brown depositing conditioner. Dark brown hair benefits from espresso or cool chocolate shades.
Test the product on a small section first. Some formulas are more pigmented than others. You want to neutralize brassiness without drastically changing your base color.
Usage Guidelines
Start by using the product once per week. Apply to clean, towel-dried hair and distribute evenly. Leave on for 5-10 minutes before rinsing. You can increase frequency if you want more intense toning.
These products work best as maintenance tools. Use them between salon visits to keep your color fresh. They won’t fix severely brassy hair on their own but prevent new brassiness from developing.
Wear gloves during application because the pigments can stain your hands. Also protect your clothes and towels from potential staining. The color washes out of most fabrics but better safe than sorry.
Consistency matters with color-depositing products. Regular use maintains results, while sporadic application gives uneven toning.
Protect Hair from Sun and Chlorine
Environmental factors accelerate color fading and increase brassiness. Sun exposure and chlorine are two of the biggest culprits.
UV Damage
The sun’s ultraviolet rays break down color molecules in your hair. This process happens faster on color-treated hair because the protective outer layer is already compromised. Brunettes might not notice fading as quickly as blondes, but UV damage still causes brassiness.
Hair sunscreen exists and works similarly to skin sunscreen. These products create a protective barrier against UV rays. Look for leave-in treatments or sprays with UV filters. Apply before going outside, especially during peak sun hours.
Hats provide excellent protection and add style to your outfit. Wide-brimmed hats work best, covering more of your hair. Even baseball caps help shield the top layers from direct sunlight.
Chlorine Protection
Pool water is harsh on color-treated hair. Chlorine strips away pigment and deposits green or brassy tones on brunettes. The chemicals oxidize your hair, similar to what happens with sun damage.
Wet your hair with clean water before swimming. Saturated hair absorbs less chlorine than dry hair. Think of it like a sponge that’s already full.
Apply a leave-in conditioner or hair oil before entering the pool. This creates a barrier between your hair and the chlorinated water. Coconut oil works particularly well for this purpose.
Rinse immediately after swimming. Don’t let chlorine sit on your hair for hours. Wash with a clarifying shampoo to remove chemical buildup. Follow with a deep conditioning treatment to restore moisture.
Swimming caps offer the best protection but aren’t always practical or comfortable. If you swim regularly, invest in a quality cap that seals well around your hairline.
Get Regular Gloss Treatments
Hair gloss treatments add shine while depositing subtle color. These salon services smooth your hair cuticle and create a reflective surface that makes your brunette shade look richer.
What Is a Hair Gloss?
Gloss treatments use demi-permanent or semi-permanent color mixed with a conditioning base. The formula is sheerer than regular hair dye but more concentrated than color-depositing conditioner. Professional glosses penetrate the hair shaft to even out porosity and add dimension.
These treatments don’t lighten your hair or cover gray completely. They enhance your existing color and neutralize unwanted tones. Think of gloss as a filter for your hair.
Salon vs. At-Home Options
Professional gloss treatments deliver the most dramatic results. Stylists can customize the formula to match your specific needs. They know exactly which tones to add for optimal brassiness correction.
At-home gloss kits offer a more affordable alternative. These work well for maintenance between salon visits. The formulas are less customizable but still effective for general toning and shine enhancement.
Frequency and Maintenance
Most women get gloss treatments every 4-6 weeks. The effects last longer than toning shampoo but aren’t permanent. Your hair gradually returns to its previous state as the gloss fades.
Timing your gloss appointments strategically extends your color. Schedule them midway between your regular color services. This keeps brassiness at bay without requiring constant salon visits. Here’s what regular gloss treatments provide:
Enhanced Shine: Light reflects off smoothed cuticles, making hair look healthier and more vibrant.
Even Color: Gloss fills in porous areas where color fades faster, creating uniform tone throughout.
Extended Color Life: Regular glossing means less frequent need for full color treatments.
Adjust Your Hair Care Routine
Small changes to your daily habits prevent brassiness before it starts. Your hair care routine impacts how long your color stays fresh.
Washing Frequency
Overwashing strips color faster than anything else. Each wash removes some pigment molecules from your hair shaft. Reduce washing to 2-3 times per week if possible.
Dry shampoo becomes your best friend between washes. It absorbs oil and refreshes your style without water. This gives your color time to settle and last longer.
When you do wash, use lukewarm or cool water throughout. We mentioned cool rinses earlier, but washing in cooler water from start to finish provides even better protection.
Product Selection
Sulfate-free shampoos are essential for color-treated hair. Sulfates are harsh detergents that strip away natural oils and color molecules. Gentler surfactants clean effectively without damaging your color.
Color-safe products contain ingredients that help seal the cuticle and lock in pigment. They often include UV filters and antioxidants that protect against environmental damage.
Avoid clarifying shampoos unless absolutely necessary. These are designed to deep clean and remove buildup, but they also remove color. Use them sparingly, perhaps once a month at most.
Styling Product Choices
Alcohol-based styling products dry out your hair and accelerate color fading. Check ingredient lists and avoid products with alcohol listed in the first five ingredients.
Oil-based serums and creams nourish while styling. They add moisture and create a protective layer against environmental stressors. Apply to damp or dry hair as needed.
Leave-in treatments serve double duty by conditioning and protecting your hair throughout the day. These products continuously work to maintain moisture and shield against damage.
Touch up your roots promptly when gray starts showing. Visible gray makes brassiness more noticeable by contrast. Keeping roots fresh helps your overall color look more cohesive and less brassy.

Frequently Asked Questions
Q: How long does it take to remove brassy tones from brunette hair?
A: Results vary depending on the method you use. Purple or blue shampoo shows improvement after 2-3 washes over a week. Toner treatments work immediately but take 20-30 minutes to process. Color-depositing products build results gradually over several weeks. For severely brassy hair, combining multiple methods gives the fastest results.
Q: Can I use purple shampoo and blue shampoo together?
A: Don’t mix them in the same wash. Use blue shampoo if your hair looks orange and purple shampoo if it appears yellow. If you have both types of brassiness, alternate between the two products. Use blue shampoo one wash and purple the next until you find which works better for your specific hair.
Q: Will toning my hair make it darker?
A: Toners don’t significantly darken your hair. They deposit cool pigments that neutralize warm tones, which might make your hair appear slightly deeper. The change is usually minimal. If you notice your hair looks too dark or ashy, reduce the processing time on your next application.
Q: How often should I deep condition color-treated hair?
A: Most brunettes benefit from deep conditioning once or twice weekly. Very damaged or porous hair needs more frequent treatments. Pay attention to how your hair feels. If it’s dry or rough, increase frequency. If it feels heavy or greasy, cut back to once per week.
Q: Do I need to use all nine methods to prevent brassiness?
A: No, you don’t need to implement every single method. Start with 3-4 techniques that fit easily into your routine. Color-correcting shampoo, cool water rinses, and limiting heat styling are good starting points. Add other methods as needed based on your results and lifestyle.
Q: Can hard water cause brassy tones in brunette hair?
A: Yes, hard water deposits minerals like iron and copper on your hair. These minerals oxidize and create brassy, orange, or even greenish tones. Installing a shower filter removes these minerals before they reach your hair. Clarifying shampoo once monthly also helps remove mineral buildup.
Q: Is it better to air dry or blow dry color-treated hair?
A: Air drying is always better for maintaining color. Heat from blow dryers accelerates color fading and can bring out brassy tones. If you must blow dry, use the lowest heat setting and always apply heat protectant first. Let your hair air dry partially before using the dryer to minimize heat exposure.
Q: How do I know if I need purple or blue shampoo?
A: Look at your hair in natural daylight. If your brunette hair has yellow or golden tones, use purple shampoo. If it looks orange, red, or copper-toned, blue shampoo is what you need. Some brunettes have both types of brassiness and may need to alternate between the two products.
