Ever Wonder Why Hair Extensions Tone Pink?

Ever applied toner to your extensions, hoping for gorgeous ash tones, only to see them turn an unflattering pink or orange? If you’re a hairstylist or color specialist, you’ve probably faced this all-too-common (and frustrating) scenario. You’ve meticulously matched the color, applied toner like a pro, and yet the result isn’t what you anticipated. Why does this happen?

Don’t worry—we’ve got answers. This guide uncovers why hair extensions tone differently than natural hair, why discoloration like pink or orange happens, and how you can prevent it. And if you’re tired of fighting stubborn color transformations, stick around—we’ll introduce extensions that truly behave like natural hair.

The Science Behind Hair Extensions

Hair extensions might look like natural hair, but their structure and processing often make them behave differently. Here’s why:

Composition Differences

Natural hair grows from the scalp, nourished by natural oils that protect its structure and integrity. On the other hand, extensions are detached from this natural cycle. Without the scalp’s protective oils, extensions become more porous and prone to absorbing environmental damage and chemicals unevenly.

How Extensions Are Processed

Extensions, especially light or blonde ones, often start as dark hair from donors across places like India, Russia, or China. To achieve lighter shades, these strands undergo intensive bleaching processes that strip away melanin (the pigment responsible for hair color). Unlike your natural hair, which undergoes gradual wear and tear, these treatments can leave extensions structurally weaker. Many brands coat them with silicones to fake smoothness, but this washes off, leaving the hair more vulnerable.

The Role of Quality and Ethics

Not all extensions are created equal. High-quality hair, like Prolonged Hair's ethically sourced virgin Remy strands, retains its cuticle layer, ensuring it mimics the behavior of your natural hair. Cheaper options often rely on harsh chemicals and poor processing, making them more likely to discolor when toned.

What Happens During Toning?

To understand why extensions turn pink or orange, it’s essential to first understand what toner does.

How Toner Affects Hair Color

Toners deposit pigments, like violet or ash tones, to neutralize unwanted warm hues (yellow or orange). For example:

• Violet pigments cancel out yellow undertones (think brassiness).
• Ash or blue pigments neutralize orange tones.

For your natural hair, toner interacts with a mix of natural melanin and your hair's porosity. Extensions, however, behave differently due to their compromised structure, making discoloration more likely.

Pigment Dynamics in Extensions

Here’s why extensions are more prone to uneven toning:

• Residual Pigments: Even after bleaching, extensions can retain underlying pigments (particularly pheomelanin, which creates red/yellow tones). When toner fades, these undertones re-emerge as pink or orange.
• Porosity: Extensions are more porous than natural hair, which means they absorb toner pigments quickly, but these pigments also fade faster, exposing warm undertones.
• Lack of Natural Oils: Without natural scalp oils to coat and protect strands, extensions have less defense against environmental damage and chemicals.

Why Extensions Turn Pink

Nearly all stylists will encounter extensions turning pink at some point. Here’s why it happens:

Fading Toner

Toner pigments applied to extensions fade faster due to increased porosity, revealing the underlying residual warmth. For very light blonde extensions, warm red/yellow tones can visually appear as pink when exposed.

Environmental Damage

Chlorine, UV rays, and hard water strip away toner and damage extensions, exaggerating discoloration. Sunscreens containing avobenzone are a known culprit, triggering chemical reactions that leave extensions pink or orange.

Previous Chemical Treatments

Extensions processed with harsh chemicals or textile dyes may behave unpredictably. When these dyes interact with toner, unintended pink or brassy hues emerge over time.

Practical Tips to Achieve Consistent Results

Now that you know why discoloration happens, here’s how to avoid it and create flawlessly toned extensions every time.

Pre-Toning Prep

• Malibu C Treatments: Use these treatments to remove mineral buildup caused by hard water or previous color treatments.
• Clarify First: Wash extensions with a sulfate-free clarifying shampoo before toning.
• Strand Test: Always test toner on a single strand first to gauge absorption and fade behavior.

Application Techniques

• Dilute the Toner: Mix toner with a developer and dilute with conditioner to slow the absorption onto porous extensions. This ensures even application.
• Blend Extensions and Natural Hair Seamlessly: Match tones carefully before application so the results look cohesive.
• Check Progress Often: Since extensions are more porous, they take to toner faster. Monitor them closely and rinse as soon as you achieve the desired effect.

Maintenance to Prevent Fading

• Use Color-Safe Products: Silver or purple shampoos help maintain cool tones and neutralize brassiness.
• Shield Against Chlorine & UV Rays:
  • Wear a swim cap or avoid pool water altogether.
  • Apply a UV-protective spray to extensions 
• Minimize Heat Styling: Heat accelerates fading, so use heat tools sparingly or with a thermal protectant.
• Soft Water Solutions: Install a water softener or use distilled water for washing to prevent mineral buildup.
