Blonde hair extensions turning pink or orange is a common problem we deal with at Beauty Club London, especially during the summer season. The ‘root’ cause is a chemical reaction that strips away the violet and ash pigments in the hair, revealing the warm tones underneath.
The most common culprits are skincare ingredients (specifically Avobenzone and Octocrylene, found in many sun creams and other skincare products), hard water, sea water, chlorine, and even perfume. The good news? It’s preventable, and in most cases, it’s fixable too. Below, we’ll break down exactly why your extensions have changed colour, how to reverse it, and what to do so it doesn’t happen again.
What Causes Hair Extensions to Turn Pink or Orange?
There are several triggers that cause extensions to discolour and in many cases it’s a combination of more than one. Here are the main offenders.
1. Skincare Products: The Biggest Culprit
This is the one that catches most people off guard. Two common UV-filtering ingredients, Avobenzone (sometimes listed as Butyl-Methoxydibenzoylmethane on the product label) and Octocrylene, are found in a wide range of skincare products, including sun creams, moisturisers with SPF, and facial sunscreens. When these ingredients come into contact with your hair extensions and are exposed to UV light, they react with the keratin in the hair. This reaction oxidises the hair, lifting out the cool-toned pigments and leaving behind pink, peach, or orange tones.
It doesn’t even require direct application to your hair. Running your hands through your extensions after applying sun cream, using an SPF moisturiser on your face and neck, or simply having your hair resting against sun-creamed shoulders is enough to trigger the reaction.
2. Hard Water
Hard water contains high levels of minerals like calcium, iron, and copper. Over time, these minerals build up on the hair shaft and cause discolouration. If you live in or are visiting a hard water area, regular washing can gradually turn your extensions pink or peachy.
3. Sea Water and Chlorine
Salt water is a natural dehydrator. It strips moisture and pigment from your extensions, leaving them dry, rough, and off-tone. Chlorine in swimming pools causes similar damage, pulling colour from the hair and leaving it looking brassy or warm. In some cases, heavy chlorine exposure can even leave a greenish tinge.
If you’re heading on holiday and plan to swim, it’s worth reading our guide on whether you can swim with hair extensions for practical tips on protecting them in the water.
4. Perfume
This one surprises a lot of people. Some perfumes and body sprays contain alcohol and chemical compounds that can react with processed hair. Spraying perfume near your extensions, or directly onto them, can contribute to discolouration over time. It’s a small thing, but sweeping your hair out of the way before you spritz makes a real difference.
5. Sun Exposure
UV rays on their own can lighten and warm up the tone of your extensions, just as prolonged sun exposure will lighten natural hair. Combined with any of the other factors above (especially Avobenzone-containing skincare), sun exposure accelerates the process significantly.
Why Does This Happen to Extensions But Not Your Natural Hair?
This is the question our clients ask us most often at Beauty Club London, and the answer is straightforward. Your natural hair is attached to your scalp, which continuously produces sebum (natural oils). These oils coat each strand and act as a protective barrier against minerals, chemicals, and all the other daily wear and tear your hair goes through.
Hair extensions, no matter how high-quality they are, don’t have access to those protective oils. They’re more porous and more exposed, which means they absorb and react to chemicals faster. This is also why a proper hair extensions aftercare routine matters so much. Extensions need you to provide the protection that natural hair gets automatically.
It’s also worth understanding the science behind the colour itself. We asked our Colour Director, Moe Harb, to explain:
“Most hair extensions, even blonde ones, start their life as naturally dark hair. Sourcing varies from brand to brand, but the processing is similar across the board. The hair is lightened from its base colour to achieve the desired shade, and during this process, violet and ash pigments are added to neutralise the natural warm tones, just as I would when lightening a client’s natural hair in the salon. When those cool pigments get stripped out by chemicals or minerals, the warm tones underneath are all that’s left, which is why you end up with pink or orange rather than any other colour.”
How to Fix Hair Extensions That Have Turned Pink or Orange
If the damage is already done, don’t panic. Our stylists have helped plenty of clients fix exactly this problem, and in most cases, the discolouration can be fully reversed.
Use a Purple or Silver Shampoo
For mild brassiness or a slight warm shift, a good quality purple or silver shampoo can help reintroduce violet pigments and cool the tone back down. Leave it on for a few minutes longer than you would on natural hair, but keep a close eye on it so you don’t over-tone. Our guide to the best shampoo and conditioner for hair extensions covers exactly what to look for and what to avoid.
Try a Chelating or Hard Water Treatment
For more noticeable discolouration, especially if hard water or mineral build-up is the cause, a chelating treatment is your best option. These are specifically designed to draw out mineral deposits and impurities from the hair, restoring the original tone. Malibu C Hard Water Wellness sachets are widely recommended for this and are available to use at home.
A few things to keep in mind with chelating treatments:
- You may need more than one sachet depending on the amount of hair extensions you have. Check with your stylist if you’re unsure.
- For severe discolouration, you may need to repeat the treatment two or three times.
- Always follow up with a deep conditioning treatment afterwards, as the process can leave hair feeling dry. When conditioning, apply only to the mid-lengths and ends and avoid your extension attachment points, as product build-up around the bonds or tapes can cause them to slip. Our guide on how to wash hair extensions like a pro covers the full technique in detail.
See a Professional for Toning
If the pink or orange tone is stubborn or particularly uneven, it’s best to give your stylist a visit. A professional toner can neutralise the unwanted warmth precisely and evenly, without risking over-processing. This is especially important for bonded or tape-in extensions, where you can’t simply remove and treat them as easily as clip-ins.
I always recommend starting with the gentlest fix first: Try a purple shampoo, then move to a chelating treatment if needed. If neither fully corrects it, come in and we’ll tone it professionally. The last thing you want to do is pile on harsh treatments without knowing what’s actually causing the issue.
How to Stop Your Hair Extensions Turning Pink in the First Place
As the saying goes, prevention is better than cure, and it’s quite a lot cheaper than professional colour correction too. Here’s how to keep your extensions protected from unwanted tones.
Check Your Skincare Ingredients
This is the single most effective thing you can do. Before your next holiday, or even before a sunny day in the park, check the ingredients list on your sun cream, SPF moisturiser, and any other skincare you apply to your face, neck, or body. Avoid products containing Avobenzone and Octocrylene. Look for mineral-based sunscreens that use zinc oxide or titanium dioxide instead. These sit on top of the skin rather than being absorbed, so they’re far less likely to react with your hair. They’re also generally better for sensitive skin, according to the Cleveland Clinic, which is a nice bonus.
When applying any sun cream or SPF product, let it fully absorb into your skin before letting your hair down. Better yet, tie your extensions up while you apply and keep them away from your neck and shoulders during the day if you want to be extra careful.
Rinse Your Hair After Swimming
If your extensions get wet in the sea or a swimming pool, rinse them with clean, fresh water as soon as possible. This helps wash away salt, chlorine, and minerals before they have a chance to build up and cause discolouration. For more detailed advice on protecting your extensions while travelling, our hair extensions on holiday guide covers everything you need to know.
Keep Perfume Away From Your Extensions
Make it a habit to sweep your hair forward or to one side before spraying perfume on your neck, chest, or wrists. It only takes a second and it removes one more potential source of chemical exposure.
Worth noting too: most perfumes are made from 60 to 95% alcohol, which is actually one of the main active ingredients in tape extension removal solution, so regular contact can weaken your extensions attachment points over time as well.
Use the Right Shampoo in Hard Water Areas
If you live in or are visiting a hard water area, consider using a chelating or hard water shampoo regularly. This will prevent mineral build-up before it has a chance to affect your colour. It’s a particularly good idea to pack one for holidays abroad, where the water quality may be different from what you’re used to at home.
Protect Your Extensions From the Sun
On very sunny days, wearing a hat or loosely tying your hair up can help reduce UV exposure. If you’re spending a full day outdoors, a UV-protective hair spray adds another layer of defence. This is good practice for your natural hair too, not just your extensions.
When to Consider New Extensions
Sometimes, particularly with very severe or repeated discolouration, the damage can go beyond what shampoo and toner can fix. If the hair has become dry, brittle, or the texture has changed significantly alongside the colour shift, it may be time for a fresh set. This is particularly true if the extensions have been exposed to chlorine or hard water repeatedly over a long period.
At Beauty Club London, our team can assess your current extensions and give you personalised advice on whether they can be restored or whether a replacement would give you a better result. If you’re considering new extensions, or if your current set needs attention, book a consultation with our extensions team and we’ll find the right solution for your hair.
Frequently Asked Questions
Why have my hair extensions turned pink on holiday?
Holidays are the perfect storm for extension discolouration because so many triggers are happening at once: sun cream and skincare on your skin, sea water, chlorine from pools, intense UV exposure, and often hard water in your accommodation’s shower. The two most effective things you can do are switch to Avobenzone and Octocrylene-free skincare, and rinse your extensions with fresh water straight after swimming.
Can I fix orange or pink extensions at home?
Yes, in most cases. Start with a purple or silver shampoo to see if that cools the tone enough. If the discolouration is more pronounced, use a chelating treatment like Malibu C Hard Water Wellness to remove mineral build-up. For severe cases, or if the colour is patchy and uneven, visit your stylist for a professional toner. Always follow up with a moisturising conditioner, as these treatments can leave extensions feeling dry.
What sun cream is safe to use with hair extensions?
Look for mineral-based sunscreens that use zinc oxide or titanium dioxide as their active ingredients, and avoid any product listing Avobenzone or Octocrylene on the label. Mineral sunscreens sit on the skin’s surface rather than being absorbed, which significantly reduces the risk of a chemical reaction with your hair. Always let your sun cream absorb fully before letting your hair touch your skin.
Why have my extensions gone peach but my natural hair looks fine?
Your natural hair receives protective oils from your scalp that act as a barrier against minerals and chemicals. Extensions don’t have this protection, making them more porous and more vulnerable to colour changes. The underlying warm pigments in processed hair extensions are also typically stronger than those in naturally light hair, which is why extensions can turn visibly pink or orange while your own hair stays looking normal.
How do I stop my blonde hair extensions turning pink?
The key steps are: avoid skincare products containing Avobenzone and Octocrylene, rinse your extensions with fresh water after swimming in the sea or pool, keep perfume away from your hair, use a chelating shampoo if you’re in a hard water area, and minimise prolonged sun exposure by wearing a hat or tying your hair up. Following a consistent aftercare routine will also keep your extensions in the best possible condition.
Do all hair extensions turn pink or orange?
It’s most noticeable in blonde and light-coloured extensions because the contrast between the cool-toned surface pigment and the warm underlying pigment is greatest. Darker extensions can still be affected, but the colour change is less visible. Higher quality human hair extensions that have been processed carefully tend to hold their colour better, but no extension is completely immune to chemical reactions from skincare products, chlorine, or mineral-rich water.
