How to Avoid Brassy Tones as the Weather Gets Warmer

How can you stop brassy tones from ruining your hair colour as the weather heats up? You can prevent unwanted warmth by protecting your hair from UV rays and chlorine, using professional-grade toning products, and sticking to a steady, hydrating routine that supports your hair health. By understanding what causes these brassy changes, you can easily keep your tailored colour looking fresh, vibrant and cool all summer long.

What Are Brassy Tones and Why Do They Worsen in Warmer Weather?

Brassy hair happens when unwanted warm shades-like yellow, orange or red-start showing up in your coloured hair. When we lighten your hair with expert techniques like balayage or foils, we lift out the darker pigments, but the underlying warm tones are much more stubborn. As mentioned in our intro, UV rays, pool chlorine and extra washing during the warmer months speed up colour fading, letting those hidden warm tones peek through.

What Does Brassy Hair Look Like?

Brassy hair has a few clear signs depending on your tailored colour. On platinum or icy blondes, it usually shows up as a strong yellow or golden tone. For brunettes, it often looks like a deep orange or copper shade. Basically, it’s any warm tone you didn’t ask for during your stylist consultation. Your hair might also look flat, dull, uneven or slightly metallic.

Why Does Warm Weather Cause More Brassiness?

During the warmer months, your hair faces a lot more environmental stress. Sunlight speeds up oxidation, which opens the hair cuticle and lets your cool-toned colour escape. Add in frequent swims in chlorinated pools or salty ocean water, plus extra washing to rinse away sweat, and your colour can fade fast, leaving just the warm base behind.

Which Hair Colours Are Most Prone to Brassiness?

Any hair that has been lightened can turn brassy, but your natural base and underlying pigments determine how quickly it happens.

Blonde and Lightened Hair

Blonde hair-especially if you've had a heavy session of foils for an icy or platinum finish-is usually the most likely to go brassy. Lightened hair is more porous, meaning it easily soaks up minerals from tap water and pollution, which alters the tone. If you started with a darker base before going blonde, you’ll naturally see those warm yellow or gold tones pop up sooner.

Brown, Dark, and Red-Toned Hair

Brunettes experience brassiness too, usually as an orange or red copper tint. Because brown and dark hair naturally has strong underlying red and orange pigments, lightening it makes those warm tones want to break through. Even cool auburns, silver or pastel shades can shift, so keeping up with your hair health is essential for everyone.

What Factors Contribute to Brassy Tones as Temperatures Rise?

As we covered above, summer elements are tough on hair. But environmental factors aren't the only things changing your cool, fresh colour into something dull.

Sun Exposure and UV Damage

The Australian sun is gorgeous, but it quickly breaks down artificial colour pigments. Just like leaving clothes in direct sunlight, UV rays fade your tailored colour and expose the raw, warm tones underneath.

Chlorine and Salt Water Effects

Pool days and beach swims dry out your hair. Chlorine is incredibly harsh and can even leave blondes with a greenish tint, while salt water increases porosity. This makes your hair act like a sponge for things that cause discolouration.

Heat Styling and Chemical Processing

Regular blow-drys and heat styling with straighteners or curling wands can lift the cuticle and let colour fade quicker. High temperatures speed up oxidation, bringing out those warm tones. This is why having an expert stylist formulate your colour properly is so crucial to achieving an ashy or cool result from the start.

Product Buildup and Over-Washing

Using shampoos with strong sulphates or washing your hair too often strips away your colour. Plus, leftover styling product residue and hard water minerals can coat the hair, making it look dull and warm.

Common Mistakes That Can Increase Brassiness

Sometimes our daily routines work against our hair goals. Avoiding a few common habits helps you maintain a confidence-boosting colour for longer.

Frequent Heat Styling Without Protection

We all love a smooth finish, but styling without a heat protectant is a fast track to brassy hair. High heat dries out the strands and speeds up fading. It also damages your hair health, making it more vulnerable to the sun and water.

Neglecting Conditioner for Colour-Treated Hair

Toning products are fantastic, but they can occasionally feel drying. A common mistake is skipping a high-quality, hydrating conditioner afterwards. Lightened hair needs extra moisture to stay soft and shiny so your colour doesn't look flat.

Ignoring Product Build-Up

When pollution, minerals and heavy styling products build up, they create a barrier that stops toning shampoos from working evenly. Using a gentle clarifying wash every so often helps remove this residue so your toners can do their job.

How Can You Prevent Brassy Tones in Warm Weather?

Stopping brassiness before it starts is the best strategy. A few easy tweaks to your routine will keep your hair looking fresh in the warmer months.

Minimise Sun Exposure and Use UV Protection

If you’re spending the day outside, pop on a hat to shield your hair. We also recommend using professional styling products with UV protection-like those from our trusted evo range-to act as a barrier against colour fade.

Reduce Swimming-Related Brassiness

Before diving into the pool or ocean, wet your hair with clean tap water. Your hair will soak up the fresh water, leaving less room for chlorine or salt. After swimming, rinse it out immediately and apply a leave-in conditioner.

Wash Hair With Cool Water

Hot showers might feel lovely, but they open the cuticle and wash away your colour. Washing with cool or lukewarm water keeps the cuticle flat, locking in moisture and your gorgeous tone.

Avoid Over-Washing and Harsh Shampoos

Try to stretch out your wash days to keep natural oils intact. When you do wash, stick to gentle, sulphate-free options. A good dry shampoo is perfect for soaking up oil between washes without stripping your colour.

Schedule Regular Trims and Treatments

Healthy hair holds colour so much better. Booking in for a regular haircut every 6 to 8 weeks keeps split ends away. Combining this with in-salon keratin treatments or hydrating masks improves your hair's manageability and shine.

What Products Help Reduce or Eliminate Brassiness?

When unwanted warmth starts creeping in, using the right products at home can make a massive difference to your confidence and your colour.

Choosing Purple or Blue Shampoos and Conditioners

It's basic colour theory: purple cancels out yellow, and blue cancels out orange. Blondes and those with silver shades should use purple shampoo, while brunettes benefit from blue. Use them once or twice a week, leaving them in for a few minutes, and always follow up with a deeply moisturising conditioner.

Using Colour-Neutralising Toners and Masks

If you need a bit more power between salon visits, a toning mask is brilliant. They offer stronger neutralisation than standard shampoos while also delivering a heavy hit of moisture and repair to support your hair health.

Trying At-Home Gloss or Salon Toning Treatments

While at-home glosses are okay in a pinch, nothing beats a professional salon toning treatment. We can expertly mix a demi or toner tailored exactly to your hair’s needs. This helps banish brassiness and adds beautiful shine that lasts much longer than home treatments.

What Is the Best Hair Care Routine for the Warmer Months?

A consistent routine is the secret to modern styling and long-lasting colour. The goal is to protect, hydrate and gently tone.

Weekly Use of Toning Products

Introduce your purple or blue toning products once or twice a week. On your other wash days, stick to your gentle, colour-safe shampoo. Swapping your regular conditioner for a hydrating toning mask once a week is a great way to refresh your look.

Hydrating and Strengthening Treatments

Sun and extra washing dry out your locks quickly. Incorporate nourishing treatments, like those from our professional evo range, to reduce damage. Applying a leave-in conditioner before you head out helps keep your hair smooth and manageable.

Taking Care Before and After Colouring

Great colour starts with healthy hair. If you have buildup, a clarifying wash before your stylist consultation ensures your new colour takes evenly. We always formulate cool-based toners or tints to keep your hair looking its absolute best from the moment you leave the chair.

When Should You Seek Professional Advice?

At-home care goes a long way, but sometimes you need an expert stylist to get your hair health and colour back on track.

Signs of Damage Beyond Home Care

If your hair feels incredibly dry, is snapping, or looks patchy and overly orange despite your best efforts, it’s time to reach out. Sometimes the underlying warmth is just too stubborn, and you need a professional colour correction to fix it gently without causing more stress to your strands.
