The hidden ingredient fading your extensions: what you need to know about Avobenzone

You’ve got your dream hair, glossy, full, and flawless. Your skincare routine is perfected, your SPF is non-negotiable, and you’re ready to take on summer. But suddenly, your bright blonde or golden balayage extensions start looking a little… off.

Not brassy from bad toner and not sun-bleached. Just subtly dull and tinged with a peachy-orange hue.

Before you panic, here’s the sneaky truth: your sunscreen (or even your face moisturiser) could be the reason.

Let’s talk about avobenzone, the summer skincare hero that doesn’t always play nicely with your extensions.

What is avobenzone and why is it everywhere

Avobenzone is a chemical UV filter that absorbs UVA rays and protects your skin from premature ageing and sun damage.

You’ll find it in almost every SPF product on the shelf, but it doesn’t stop there. Many moisturisers, tinted serums, perfumes, foundations, and body lotions also include it to give you all-day sun protection.

It’s gentle on skin, lightweight, and great for daily wear, but when it comes to your hair extensions, it can be a little problematic.

The science behind the stain

Here’s where things get a little science-y (but we’ll keep it simple).

When avobenzone comes into contact with minerals like iron or copper, a chemical reaction happens. These minerals are found in ocean water, swimming pools, and even tap water in some areas.

When that oxidation occurs, it can cause colour changes in hair extensions, especially lighter tones.

The result? That beautiful, creamy blonde can shift into unwanted orange or peachy hues, almost like your extensions have had a mini fake tan you definitely didn’t ask for.

And before you start blaming your extensions, no need. Even the highest quality human hair, like Hair Wonderland’s double-drawn Russian/Mongolian strands, can experience this reaction. It’s about chemistry, not quality.

How to spot it early

If you’ve been spending more time outdoors or recently switched to a new sunscreen, look out for these signs:

• Subtle orange or peach undertones in blonde extensions
  

• Uneven colour patches or dullness
  

• Hair feeling coated or “film-like” after applying skincare
  
  

Often, this happens after swimming or holidays, when SPF, salt or chlorinated water, and minerals combine to create the perfect storm for discolouration.

Tip: compare your extensions to a spare weft or colour ring. You’ll notice the difference instantly.

Prevention is way better than cure

The good news is that you can absolutely enjoy the sun and still protect your hair. Here’s how:

1. Choose your SPF wisely.
Opt for mineral-free or avobenzone-free sunscreens. Look for formulas that use ingredients like zinc oxide or titanium dioxide instead. Some great options include La Roche-Posay Anthelios Invisible Fluid, Ultra Violette’s Queen Screen, or any “mineral-only” SPF.

2. Keep hair up during pool or beach days.
Tie your extensions into a loose braid or bun, or wrap them in a silk scarf to protect them from exposure.

3. Rinse immediately after swimming.
Fresh water helps wash away any residue before it reacts with your hair.

4. Be mindful of skincare near your hairline.
Avoid applying SPF or body products with avobenzone directly along your hairline, neck, or shoulders. These are the first areas your extensions can come into contact with.

5. Use a clarifying or chelating shampoo occasionally.
These shampoos help remove mineral build-up from hard water or salt exposure. Follow up with a hydrating conditioner to keep your extensions soft and glossy.

And of course, finish your routine with Hair Wonderland’s Detangle Brush or Tangle Tamer to keep your strands smooth and silky without causing damage.

If it’s already happened, don’t panic

If your extensions are already showing signs of discolouration, there are a few ways to tone it down:

• Use a gentle purple shampoo or toner to help neutralise orange hues.
  
  

• For more noticeable discolouration, your stylist can perform a professional toning service.
  
  

• Avoid using any bleach or box dye at home, as this can permanently damage the hair.
  
  

Think of it as a small reset. Your stylist will know exactly how to bring your extensions back to their perfect shade.

Protect your investment

You invest in beautiful, premium extensions, and they deserve to be cared for like the luxury they are.

Avobenzone isn’t the enemy, it’s just one of those ingredients that doesn’t mix well with your kind of fabulous. By being aware of the products you use and taking a few simple steps, you can keep your extensions looking salon-fresh all summer long.
