You know that feeling? Walking out of the salon with a fresh, vibrant colour, feeling like a million bucks. But then, a few washes later, that stunning shade starts looking a bit… well, sad. It’s a real downer, especially when you’ve invested your time and money into getting that perfect look.
Watching your beautiful colour literally go down the drain isn't just bad luck. It's a sign that your hair is sending out an S.O.S.
Why Your Coloured Hair Is Crying Out for a Lifeline
When you colour your hair, its structure changes. It becomes more porous and a little more fragile, making it an easy target for a whole host of colour-fading culprits.

The Usual Suspects Behind Faded Colour
Your everyday routine might actually be a battlefield for your hair colour. The enemies are often hiding in plain sight.
- Harsh Shampoos: A lot of regular shampoos have a high pH level. This essentially forces your hair’s protective outer layer (the cuticle) to open up, letting those precious colour molecules make a run for it.
- The Great Outdoors: The harsh Aussie sun is no joke. Its UV rays can act like a natural bleach on your hair, while minerals in hard water can build up and leave your colour looking flat and dull.
- The Heat is On: Love your straightener or curling wand? Without the right protection, all that heat can speed up the fading process, leaving your hair feeling dry and looking fried.
Getting your head around these challenges is half the battle. We dive deeper into this in your guide to colour-treated hair care.
Think of your hair's cuticle like the scales on a pinecone. When they’re lying flat and sealed, everything inside is safe and sound. But when they get ruffled and stand up, everything can escape—including that gorgeous colour you paid for.
This is exactly why a specialised shampoo isn't just a nice-to-have; it's a must-have. Biolage Color Last Shampoo was designed specifically to tackle these problems head-on, giving your colour the backup it needs to stay brilliant and true for far longer.
The Secret Science of Sealing in Your Colour
Ever wondered how Biolage Color Last Shampoo actually works its magic? It’s not just some fancy cleanser; think of it as a personal bodyguard for your hair colour. It wraps each strand in an invisible shield, locking in that stunning salon shade and stopping it from becoming a faded memory.
The real hero in this story is its low pH formula. Now, that might sound a bit like a high school chemistry lesson, but the idea is actually dead simple. Most regular shampoos are alkaline (high pH), which forces your hair's protective outer layer—the cuticle—to swell up and open. When that happens, colour molecules can't wait to make a run for it every time you wash.
Biolage Color Last does the complete opposite. Its low pH helps keep that cuticle layer smooth and tightly sealed, essentially trapping the colour inside where it belongs. Genius, right?
Keeping Your Colour Locked In
This gentle, slightly acidic environment is your best defence against the dreaded colour washout. Instead of stripping your hair, it maintains the delicate balance needed to keep your colour’s depth, tone, and vibrancy alive and kicking for much longer.
It’s pretty straightforward: your hair stays vibrant when the cuticle is sealed. That’s exactly what a low pH shampoo like Biolage Color Last is engineered to do. It’s the difference between locking your valuables in a secure vault and leaving the door wide open.
This is what we mean when we talk about keeping that beautiful, reflective shine on your colour-treated hair.

The image above perfectly captures that smooth, glossy surface you get when the cuticle layer is sealed, protecting the gorgeous colour underneath.
This clever formulation is designed to keep your salon colour looking fresh for up to 20 washes when you pair it with the matching conditioner—a massive win for anyone with coloured hair in Australia. It’s also packed with goodies like soybean oil to help strengthen your hair and protect it from UV damage. You can explore more of its protective features on our product page.
Alright, let's pop the hood and see what makes this shampoo tick. It’s not just a bottle of bubbly goodness; the magic is in the mix. Biolage has packed Color Last with a dream team of ingredients designed to treat your coloured hair like the VIP it is.
The real star of the show? Orchid Flower Extract. No, it’s not just in there to sound fancy. Orchids are nature’s masters of keeping their colour vibrant and breathtaking for ages. Biolage has bottled that same resilience, creating a natural shield for your hair.
It's like a bodyguard for your hair colour. The extract mimics the orchid's own UV filters, helping to protect your perfect shade from the fade-out caused by sun and daily washing.
But it’s not all about playing defence. Your hair needs some TLC, especially after a colouring session, which can leave it feeling a bit delicate. That’s where ingredients like soybean oil come in to swoop in and save the day.
This stuff is a moisture powerhouse. It dives deep to replenish what the colouring process takes out, bringing back that silky, touchable feel and a shine you can see from across the room. It gets to work strengthening each strand, making your hair tougher against whatever life throws at it. Here in Australia, where we're constantly battling sun and surf, having a formula that's both protective and nourishing is a game-changer. You can find the full ingredient breakdown right here at On Line Hair Depot when you Catwalk.
At the end of the day, Biolage Color Last Shampoo is far more than a one-trick pony. It’s a complete wellness package in a bottle, making sure your hair doesn't just look fabulous—it feels incredible, too.
Getting That Salon-Fresh Feeling in Your Own Shower
Okay, so you've got the good stuff. But having the right product is only half the battle – using it like a pro is where the real magic happens. Let's turn your daily wash into a proper colour-saving ritual. We're moving beyond a basic 'lather, rinse, repeat' here.
First things first, let's talk amount. It's so tempting to squeeze a giant dollop into your palm, but with a salon-quality formula like this one, a little goes a very long way. For short to medium hair, you genuinely only need about the size of a 10-cent piece.
That small amount is all it takes to whip up a rich, gentle lather that cleans your hair without stripping it. Overdo it, and you're just creating build-up and washing your money down the drain.
The Two Golden Rules of Colour-Safe Washing
Want to keep that stunning colour looking fresh between salon visits? It comes down to two super simple tweaks to your routine. They might seem small, but trust me, they make all the difference.
-
Dial Down the Temperature: I know, a steaming hot shower feels amazing, but it's a total nightmare for your hair colour. Hot water blasts open the hair's cuticle, which is like opening the floodgates for your colour molecules to wash away. Stick to lukewarm water for washing and rinsing – your hair will thank you for it.
-
Conditioner is Non-Negotiable: Seriously. Don't skip this step. Shampooing does the cleaning, but in the process, it slightly lifts the hair's protective cuticle layer. The Biolage Color Last Conditioner from our range is designed to be the perfect follow-up act, smoothing that cuticle right back down and sealing it shut.
Here’s a way to think about it: shampooing is like opening the door to clean out a room. Conditioning is like shutting and locking that door afterwards to make sure nothing precious gets out. If you skip the conditioner, you're leaving the door wide open for your colour to fade.
When you use the shampoo and conditioner together, you’ve got a powerful tag team that cleanses, nourishes, and most importantly, locks in that gorgeous colour. It’s your secret weapon for making that vibrant shade last.
Building Your Complete Colour Protection Arsenal

While the Biolage Color Last Shampoo is a true hero for your hair, every hero needs a super-squad to back them up. Think of it as your star player; it gets the game started beautifully. But for a total, game-changing victory over colour fade, you need the entire team working in perfect harmony.
We’ve brought the whole Biolage Color Last family together right here, making it your one-stop shop for building an impenetrable fortress around your hair colour. It’s all about creating a system where each product amplifies the effects of the next, delivering results you can really see and feel.
The Power Couple Conditioner
First up in your arsenal is the non-negotiable Biolage Color Last Conditioner. If the shampoo gently opens the door to cleanse your hair, the conditioner is the expert that follows right behind to seal the deal.
Its main job is to smooth and close the hair cuticle, which gets slightly lifted during washing. This step is absolutely crucial for locking in moisture and, more importantly, those precious, vibrant colour molecules you want to protect. Using the shampoo without its conditioner partner is like leaving your front door wide open—you’re just asking for trouble!
A complete system works synergistically. The conditioner doesn't just soften your hair; it completes the protective process started by the low-pH shampoo, ensuring maximum colour retention and shine.
The Deep Nourishment Reinforcement
For those moments when your hair is crying out for a serious dose of TLC, it's time to bring in the heavy artillery: the Biolage Color Last Mask. Think of this as a weekly spa day for your strands.
This intensive treatment dives deeper than a regular conditioner, delivering a concentrated hit of nourishment to repair and fortify hair that’s been weakened by the colouring process. Using it regularly helps restore elasticity and resilience, making your hair less prone to dreaded breakage.
And let’s be real, healthy hair holds onto colour so much better. Since heat styling can also take its toll, pairing this routine with one of the 12 best heat protectant spray options in Australia is a brilliant move for total defence.
Your Biolage Color Last Questions Answered
It's smart to have a few questions before you commit to a new shampoo, even one with a reputation like this. We get it! Consider this your personal cheat sheet for everything you've been wondering about the brilliant Biolage Color Last Shampoo.
Let's get right into the nitty-gritty.
Is Biolage Color Last Shampoo Sulphate-Free?
This is the big one, isn't it? The classic Biolage Color Last Shampoo isn't technically a sulphate-free formula. But don't let that scare you off! Its magic lies in its low-pH design, which is incredibly gentle on your hair. It cleanses without being aggressive, which is exactly what your expensive colour needs to stay put.
If a completely sulphate-free routine is a non-negotiable for you, that's totally fine! We'd point you towards the Biolage R.A.W. range right here on our site for another fantastic option.
Can I Use This on Hair That Isn't Coloured?
You absolutely can! While its claim to fame is protecting your dye job, the formula itself is just beautifully nourishing for any hair type.
Thanks to goodies like Orchid Extract, it’s a brilliant moisturising shampoo for anyone. It'll leave your hair healthier, easier to manage, and with a lovely shine. So even if you're rocking your natural shade, it’s a top-tier choice.
The bottom line is that a gentle, pH-balanced, and moisturising formula is great for all hair types. Coloured hair just needs those properties a little more desperately.
How Often Should I Wash with It?
Go right ahead and use Biolage Color Last Shampoo every time you wash. To really make that colour last, we usually find that shampooing two to three times per week is the sweet spot for most people.
And please, always follow it up with the Biolage Color Last Conditioner from our store. This isn't an optional step! The conditioner is what seals the hair cuticle, locking in that vibrant colour and moisture you just worked so hard to cleanse.
For a deeper dive, you might want to check out our guide exploring if Biolage Color Last is the answer for coloured hair.
Does It Protect Against Heat Damage?
The whole Color Last system does a fantastic job of strengthening your hair, making it more resilient overall. But the shampoo itself is not a dedicated heat protectant.
Think of it this way: shampoo is for cleansing, and heat protectant is for shielding. To keep your strands safe from your straightener or curling wand, you absolutely need to add a proper heat protectant spray to your routine. We've got plenty to choose from!
