Maintaining coloured hair extensions can be challenging because they don’t benefit from natural scalp oils and are prone to dryness, fading, and damage. Using the wrong products can weaken bonds, cause slippage, and shorten the lifespan of your extensions. Here’s what you need to know:
- Shampoos: Opt for sulphate-free, pH-balanced formulas like Color WOW Color Security Shampoo or Pureology Hydrate Sheer Shampoo to preserve colour and prevent bond damage.
- Conditioners: Lightweight, hydrating options like Beauty Works Pearl Nourishing Conditioner or Limitless C2 Colour Care Conditioner help lock in moisture without build-up.
- Treatments: Weekly deep conditioning masks (e.g., Amika Hydro Rush Intense Moisture Hair Mask) and bond-strengthening products (e.g., K18 Leave-In Molecular Repair Hair Mask) repair and protect extensions.
- Tools: Using the best brushes for hair extensions, like the Tangle Tamer Brush and Detangle Brush, prevent breakage and keep extensions smooth. Knowing how to detangle hair extensions properly is also essential for preventing bond damage.

What to Look for in Products for Coloured Hair Extensions
Recommended vs Avoided Ingredients for Coloured Hair Extensions
Taking care of coloured hair extensions requires more than just grabbing a product labelled "colour-safe." The right products should protect the colour, keep the extensions hydrated, and avoid build-up. Here's a breakdown of the key factors to keep in mind.
Colour-Safe and pH-Balanced Formulas
A pH-balanced formula is essential because it helps seal the hair cuticle, which locks in colour and prevents fading. Sulphate-free shampoos, for example, use gentler cleansers that don’t strip moisture or roughen the cuticle. This means your colour stays vibrant for longer, even after multiple washes.
Hydration Without Build-Up
Unlike natural hair, extensions don’t receive oils from the scalp, so they rely entirely on external hydration. This is especially true for high-quality hair, so it helps to compare Russian and Mongolian hair extensions to understand their specific maintenance needs. Lightweight moisturisers like argan oil or aloe vera are excellent choices. As The Lauren Ashtyn Collection puts it:
"If you wouldn't put it on fragile silk fabric, don't put it on your extensions. You want gentle, lightweight, hydrating products that keep your hair fresh".
This advice underlines the importance of choosing products that nourish without leaving heavy residue.
Sulphate-Free and Residue-Free Products
Sulphates and heavy silicones can be a nightmare for coloured extensions. Ingredients like Sodium Lauryl Sulphate (SLS) and Sodium Laureth Sulphate (SLES) strip moisture from the hair, leaving it dry and prone to fading. Colour WOW explains:
"Our colour protect shampoo avoids silicones and heavy conditioning agents that leave a residue, dull it, cause scalp irritation and even hair loss".
To help you navigate product labels, here’s a quick guide to what’s recommended and what to avoid:
| Ingredient Type | Recommended Ingredients | Ingredients to Avoid |
|---|---|---|
| Cleansers | Japanese amino acids, sulphate-free surfactants | SLS, SLES (Sulphates) |
| Moisturisers | Argan oil, Aloe vera, Avocado oil, Shea butter | Coconut oil, Castor oil |
| Proteins | Hydrolysed keratin, Milk protein, Oat protein | Heavy, non-water-soluble proteins |
| Finishers | Water-based silicones, pH-balanced formulas | Heavy silicones, Waxy coatings, Alcohol |
Best Shampoos for Coloured Hair Extensions
Choosing the right shampoo for coloured extensions is all about finding a formula that cleans effectively without leaving residue, stripping colour, or making it difficult to blend extensions with natural hair. The shampoos listed here are specially formulated to maintain vibrancy while keeping your extensions in excellent condition. Here are some top picks that balance thorough cleansing with colour and bond protection.
Color WOW Color Security Shampoo

This shampoo is a standout for its 100% residue-free formula, featuring a blend of eight non-stripping cleansers designed to prevent colour fading for up to 20 washes. According to the brand:
"Our color protect shampoo contains no silicones, thickening, conditioning or anti-frizz ingredients that stay behind and can weigh hair down, dull it, cause scalp irritation and even hair loss."
A 250ml bottle is priced between $39.00 and $53.00 AUD, and it boasts an impressive 4.7 out of 5 stars from 229 reviews. One satisfied customer, Anne P., shared: "Build-up is eliminated and colour stays vibrant – a must for preserving delicate bonds." This makes it an excellent option for tape-in and micro-ring extensions, where maintaining bond strength is critical. For lighter or finer extensions, this shampoo offers a gentle cleanse that won't add unnecessary weight.
Pureology Hydrate Sheer Shampoo
Pureology Hydrate Sheer is perfect for fine, delicate extensions. Its sulphate-free formula ensures gentle cleansing while protecting colour vibrancy, making it ideal for extensions that need moisture without heaviness. If you're working with finer extensions, this is a great choice for lightweight hydration. For those with clip-in or tape-in extensions, however, you might want to consider a product with a bit more robust hydration, like the option below.
ELEVEN Australia Hydrate My Hair Shampoo

Made in Australia, this shampoo is designed to deliver hydration while protecting both colour and bond integrity. Its gentle formula makes it suitable for regular use on clip-in and tape-in extensions. A 350ml bottle is priced at approximately $36.95 AUD, offering an accessible option for those looking for reliable hydration without compromising extension quality.
Best Conditioners for Coloured Hair Extensions
Choosing the right conditioner is crucial for keeping coloured hair extensions looking vibrant and healthy. A good conditioner not only locks in moisture but also shields your extensions from environmental factors. Below are some top picks designed to maintain colour, prevent build-up, and solve common extension problems to keep your hair soft and manageable.
Beauty Works Pearl Nourishing Conditioner
This conditioner is specially crafted for coloured extensions, featuring a blend of argan oil, milk proteins, and keratin. These ingredients work together to repair damage, enhance shine, and maintain the integrity of both the colour and the bonds. With no sulphates, SLES, or parabens, it’s a gentle yet effective option. Users appreciate its ability to deliver a glossy finish and silky softness. A 30ml bottle is priced at $7.95 AUD. For best results, apply it to the mid-lengths and ends, leave it on for 1–3 minutes, and rinse with warm water.
Remi Cachet Conditioner

Designed to offer lightweight hydration, the Remi Cachet Conditioner helps protect extensions from environmental stressors. It prevents slippage while keeping your extensions soft, tangle-free, and vibrant. This formula ensures your extensions stay manageable without compromising their colour or texture.
Limitless C2 Colour Care Conditioner

An Australian-made favourite, the Limitless C2 Colour Care Conditioner is packed with advanced UV filters to combat fading caused by sun exposure. Enriched with hyaluronic acid, argan oil, linseed oil, and jojoba oil, this vegan and sulphate-free formula locks in moisture and colour while improving elasticity. It has earned a 100% positive rating from 10 reviews on AMR Beauty Group. Anna Simms shared her thoughts, saying, "Love my colour care conditioner at the basin. Perfect straight after a colour. And clients just love the smell." The conditioner also features a refreshing acai berry fragrance. Prices start at $14.95 AUD for 100ml and $39.95 AUD for 1L. It works by sealing the hair cuticles, ensuring colour pigments and moisture stay locked in.
| Product | Key Ingredients | Key Benefits | Price (AUD) |
|---|---|---|---|
| Beauty Works Pearl Nourishing | Argan oil, Milk protein, Keratin | Shine enhancement and structural repair | $7.95 (30ml) |
| Remi Cachet | Lightweight hydrating agents | Colour protection and tangle-free finish | Not specified |
| Limitless C2 Colour Care | UV Filters, Hyaluronic acid, Argan oil, Linseed oil, Jojoba oil | UV protection and moisture retention | $14.95 (100ml), $39.95 (1L) |
When applying any of these conditioners, focus on the mid-lengths to the ends of your hair to avoid slippage at the bonds. Next, consider treatments that complement these conditioners to further enhance the longevity and vibrancy of your coloured extensions.
Best Treatments for Coloured Hair Extensions
Coloured extensions require weekly treatments to repair damage and keep their vibrancy intact. Unlike regular conditioners, these treatments go deeper, addressing chemical damage and extending the life of your extensions when used alongside your shampoo and conditioner routine.
Deep Conditioning Masks for Coloured Extensions
Deep conditioning masks are a must for providing the moisture that coloured extensions crave. For example, the Amika Hydro Rush Intense Moisture Hair Mask uses hyaluronic acid to deliver intense hydration. Another great option is the Goldie Locks Signature Hair Mask, which repairs damage with a colour-safe formula packed with vitamins, fatty acids, and antioxidants. This sulphate-free mask, priced at $56.00, is especially suited for extensions as it doesn’t weigh down the bonds.
To maximise the benefits of any mask, start by removing excess water from your hair. This helps the product penetrate more effectively. Apply the mask to the mid-lengths and ends, leave it on for the recommended time, and finish with a cool water rinse. The cool rinse seals the cuticles, locking in all that moisture.
Bond-Strengthening Treatments
If your extensions need more than just moisture, bond-strengthening treatments are key. These products go beyond the surface, repairing the hair's internal structure. The K18 Leave-In Molecular Repair Hair Mask is a standout, working in just four minutes to reconnect broken keratin chains and restore elasticity. As Nnor Hair explains:
"K18 goes deeper inside the hair strand to reconnect broken keratin chains and regenerate disulfide bonds that have been destroyed when bleaching or coloring hair".
For new extensions, it's recommended to use the K18 treatment during the first six washes to stabilise the hair structure.
Another excellent option is the Olaplex No. 3 Hair Repair Perfector, which focuses on regenerating disulfide bonds to prevent further damage. According to OLAPLEX:
"We've heard amazing feedback from those with extensions on how much longer they last by keeping them healthy!".
Once you’ve completed the initial six K18 treatments, you can alternate between Olaplex No. 3 and K18 every 3–4 weeks. This approach helps maintain the strength of your extensions while preventing them from becoming dry or difficult to manage. Bond-strengthening treatments are also incredibly useful during extension removal, as they make the process smoother and protect both your natural hair and the extensions from mechanical damage.

Conclusion
Taking care of coloured extensions requires a thoughtful routine using nourishing and protective products.

Harsh ingredients like protein, keratin, sulphates, or high alcohol can weaken their structure and appearance.
The best care routine includes sulphate-free shampoos, hydrating conditioners, and weekly deep conditioning treatments to keep them moisturised. Adding a treatment oil as directed helps preserve softness and manageability. For an extra touch, a cool rinse can seal the cuticles and lock in moisture.

FAQs
How often should I wash coloured hair extensions?
Hair Wonderland suggests washing clip-in extensions after every 10–15 uses. For permanent extensions, it's best to wash them 1–2 times a week. This routine helps keep the extensions in good condition and prolongs their lifespan. Consistent care is key to ensuring your extensions look their best for as long as possible.
Can I use treatment oils without loosening the bonds?
Yes, you can use treatment oils on hair extensions, but it's important to choose oils that are lightweight and specifically designed to be extension-friendly. When applying, make sure to avoid the bonds and adhesive areas to prevent any weakening. This way, your extensions will stay secure and maintain their quality.
What’s the safest way to protect extensions from sun and chlorine?
To shield your extensions from sun damage and chlorine, start by applying a UV-protective spray every day. If you're spending extended time outdoors, reapply it every 2–4 hours. For added protection, consider wearing wide-brimmed hats or wrapping your hair with a silk scarf.
Before diving into a pool or the ocean, rinse your extensions with fresh water and apply a leave-in conditioner. This creates a protective layer and reduces chlorine absorption. Also, try to limit heat styling and steer clear of using heavy products near the bonds, as these can weaken them, especially under the sun.
