So, you've taken the plunge and rocked a stunning new shade from On Line Hair Depot. The big question is: how long do you get to enjoy it? The honest answer is that it really depends, but you can typically expect your vibrant new look to last anywhere between 4 to 12 washes.
Think of our semi-permanent colour like a beautiful, high-end glaze for your hair. It wraps around the outside of each strand, giving you a brilliant burst of colour without permanently changing your hair's inner structure.
Your Guide to Our Semi Permanent Colour Longevity
It’s the ultimate way to experiment with your style—all the fun of a new look, without the 'til-death-do-us-part commitment of permanent dye. Permanent colours work by cracking open the hair's protective outer layer (the cuticle) to deposit pigment deep inside. Our semi-permanent options are much kinder; they simply coat the surface.
This means the lifespan of your colour is a bit of a choose-your-own-adventure story, shaped by your hair's unique quirks and how you treat it. For most people in Australia, this means their colour will stick around for about six weeks, assuming they wash their hair two or three times a week.
This little infographic gives you a great visual of how your colour will gently fade over time, starting from that very first wash.
As you can see, your after-care routine is your secret weapon right from day one.
The real trick to making that colour last isn't just in the dye—it's all about prepping your hair beforehand and then protecting your masterpiece afterwards. The right products from our store will become your absolute best mates on this journey.
Quick Guide to Semi Permanent Colour Lifespan
To give you a clearer picture, here’s a quick rundown of what you can expect based on your hair and habits.
| Hair Condition | Washing Frequency | Estimated Colour Lifespan (Washes) | Estimated Colour Lifespan (Weeks) |
|---|---|---|---|
| Healthy, non-porous hair | 1-2 times a week | 10-12 washes | 6-8 weeks |
| Lightly processed hair | 2-3 times a week | 6-8 washes | 3-4 weeks |
| Bleached or porous hair | 3-4 times a week | 4-6 washes | 1-2 weeks |
This table shows just how much of a difference your hair's health and your washing schedule can make. A little extra care really does go a long way!

The Secret Role of Hair Porosity
Ever wondered why the exact same shade of our semi-permanent colour looks electric on your best mate but washes out of your hair in a flash? It's not magic, it’s hair porosity. Honestly, this is the single biggest player in the game of how long your colour sticks around.
Think of each strand of your hair like a sponge. Porosity is all about how well that sponge can soak up and hold onto things—like water, and more importantly, our amazing hair colour. It’s the deciding factor for your whole colour journey, from the moment you apply it to the way it eventually fades.
What Kind of Sponge is Your Hair?
So, how does this sponge idea translate to your actual hair? Your strands will generally lean one of two ways, and each one behaves totally differently with our colours.
-
Low Porosity Hair: Picture a brand-new, dense kitchen sponge. The hair's outer layer, the cuticle, is sealed down tight. It's smooth, shiny, and tends to fight off moisture and colour molecules. This means our semi-permanent pigments have to work a bit harder to find a grip. For you, leaving the colour on a bit longer is the trick to getting that killer vibrancy.
-
High Porosity Hair: Now, imagine a well-loved, holey sponge. This hair has been through it—maybe it's been pre-lightened, heat-styled, or chemically treated. The cuticle is raised and open, practically begging for colour. Your hair will drink our dye right up, giving you a seriously intense, show-stopping result from the get-go. The catch? What goes in easily can also come out easily, often leading to a quicker fade.
Figuring out which camp you're in is your secret weapon. If you have low porosity hair, try a clarifying shampoo from our range before you colour to gently nudge those cuticles open. For high porosity hair, our colour-safe conditioners are your best friend—they help seal everything in and lock that pigment down.
Understanding if your hair is a reluctant sponge or an eager one is the key to mastering your application. Nail this, and you'll get brilliant, long-lasting results every single time you use our semi-permanent colours.
Common Habits That Fade Your Colour
So, you’ve just spent time and money getting that incredible new shade from On Line Hair Depot. It looks amazing. But now the real work begins, because some of your most innocent daily habits might be secret colour assassins, plotting to send your vibrant new look down the drain.
The biggest offender is probably your favourite part of the morning: a long, steamy shower. Hot water feels great, but it’s a nightmare for your hair. It forces the hair’s cuticle—its protective outer layer—to open up, giving those precious colour molecules a wide-open escape route.
Honestly, how long your semi-permanent hair colour lasts often boils down to a few small tweaks in your routine. Ditching a couple of bad habits for colour-friendly ones is the difference between a colour that vanishes in a week and one that truly lasts.
Everyday Colour Killers To Watch Out For
Besides turning down the heat in your shower, a few other sneaky culprits are likely lurking in your routine. Let’s shine a light on them so you can keep your colour looking salon-fresh.
-
Those Sudsy Shampoos: That rich, bubbly lather you love? It’s often thanks to sulphates. These are powerful detergents that are a bit too good at their job, stripping your hair of its natural oils and your gorgeous new colour. Always reach for a sulphate-free formula from our store, made for colour-treated hair.
-
Our Aussie Sun: We all love a bit of sunshine, but your hair doesn't. UV rays are notorious for breaking down colour pigments, much like leaving a vibrant t-shirt out on the clothesline for too long. A hat or a good UV protectant spray from our collection is non-negotiable.
-
A Quick Dip in the Pool: Planning on doing a few laps? Be warned. Chlorine is basically a bleach, and it will mercilessly pull the colour right out of your hair, leaving it dull, uneven, and sad after just one swim.
Here in Australia, our intense sun and often hard water can be especially brutal on coloured hair. This is exactly why our stylists are always recommending sulphate-free shampoos and UV sprays to keep your colour from fading into oblivion.
Turning the water temperature down to lukewarm is a fantastic start, but the products you use from our site are just as important. Knowing how to wash your hair properly is a game-changer, and our guide has some brilliant tips to help lock that colour in tight.
So, you’ve got that jaw-dropping, vibrant new hair colour and you want to keep it looking salon-fresh for as long as possible. Who wouldn’t? The secret isn’t locking yourself away—it’s about tweaking your routine with products from our website to protect that gorgeous investment.
Let’s get you set up with a few pro tips. Your mission, should you choose to accept it, is to defend your hair against its two biggest nemeses: harsh cleansers and scorching heat. It’s amazing what a few simple swaps can do to keep your colour popping.

Build Your Colour-Saving Toolkit
The easiest change you can make starts the second you step into the shower. Dial that water temperature down from "surface of the sun" to lukewarm or even cool. Super hot water lifts your hair's outer layer, the cuticle, which is like opening the floodgates for your colour molecules to escape. A cooler rinse, on the other hand, helps slam that door shut, locking your colour safely inside.
Next up: a shampoo audit. That rich, bubbly lather you get from most standard shampoos? That’s usually thanks to sulphates, which are brilliant at cleaning but also notorious for stripping colour right out of your hair. Making the switch to a professional, colour-safe shampoo from our store is a total game-changer. These formulas are designed to cleanse gently without being so aggressive. If you're not sure where to start, check out our guide to the best shampoos that are paraben and sulphate-free.
Think of it like this: you wouldn't wash a delicate silk shirt with harsh laundry detergent. Your beautifully coloured hair deserves the same specialised care, and you can find it all on our website.
Protect and Refresh Your Colour
Your colour-saving strategy doesn’t end when the water turns off. Heat styling is another major villain in the premature fading story. Before a straightener or curling wand even comes near your hair, you need to arm it with a quality heat protectant spray from our range. This simple step creates a thermal shield, protecting your strands from damage and helping to preserve the integrity of your colour.
And for that mid-cycle slump when your shade starts looking a little less punchy? Our pigmented conditioners are your secret weapon. Using one of these will deposit a fresh dose of colour while giving your hair a deep conditioning treat. It’s the perfect way to breathe new life into your look and stretch the time between full colouring sessions.
Colour-Saving Habits Do This Not That
To make it even simpler, here's a quick rundown of the habits that will keep your colour vibrant versus the ones that will send it down the drain.
| Do This (To Save Your Colour) | Not That (To Avoid Fading) |
|---|---|
| Wash with cool or lukewarm water. | Take long, steamy-hot showers. |
| Use our colour-safe, sulphate-free shampoos. | Grab any old shampoo off the shelf. |
| Always apply a heat protectant spray from our site. | Use styling tools on unprotected hair. |
| Refresh with a pigmented conditioner from our collection. | Let the colour completely fade before reapplying. |
Sticking to the "Do This" column is your ticket to a longer-lasting, more brilliant hair colour. It's all about working smarter, not harder, with the right products from On Line Hair Depot.

Your Burning Questions About Semi-Permanent Colour
So, you're on the brink of diving headfirst into the kaleidoscopic world of semi-permanent hair colour, but a few nagging questions are holding you back. Excellent! Doing your homework is the secret to getting a result you’ll absolutely love. We’ve rounded up the most common queries about our semi-permanent range to help you feel totally confident before you get colouring.
Think of this as your final checklist before the fun begins. Let’s get these questions sorted so you can get down to the business of picking your next incredible shade from our store.
Will It Actually Cover My Greys?
This is the big one, isn't it? The short answer is no, not in the traditional sense. But what it does do is pretty magical. Our semi-permanent colours are designed to deposit a sheer layer of pigment onto the hair. They don’t contain the chemicals needed to create the solid, opaque coverage you get from a permanent dye.
Instead of hiding your greys, our colours give them a gorgeous, artistic tint. Picture a watercolour wash that lets the natural dimension of your hair peek through. This creates a beautiful blending effect, making your greys look like deliberate, shimmering highlights. It's the perfect solution if you have scattered greys and want a modern, multi-tonal look instead of a flat, single block of colour.
Do I Have to Bleach My Hair First?
This all comes down to the result you’re chasing. If you're dreaming of those super vibrant, look-at-me shades from our collection—think electric blue, pastel pink, or neon green—then yes, you’ll need to start with a lightened base. Bleaching creates a clean, pale canvas that allows these vivid pigments to pop in their truest, most brilliant form.
But if you’ve got darker hair and bleaching isn’t on the cards, you can still get a stunning result! Our deeper, more saturated shades like rich burgundies, deep teals, or luscious purples will give brown hair a gorgeous, jewel-toned sheen. It’s a more subtle vibe, for sure, but when the light hits just right, your hair will reveal an incredible richness and dimension.
The key difference is how the colour works. Our semi-permanent range is a direct dye with no developer. It just coats the hair's surface and fades beautifully over several washes. This is what makes it such a gentle, low-commitment option.
What's the Difference Between Semi-Permanent and Demi-Permanent Colour?
It’s super easy to get these two confused, but they are completely different beasts. The main distinction boils down to one crucial ingredient: a developer.
Our semi-permanent colours are direct dyes. They come ready to use, straight from the bottle, and simply coat the outside layer of your hair shaft. Easy!
Demi-permanent colour, on the other hand, needs to be mixed with a low-volume developer. This developer’s job is to gently lift the hair’s cuticle just enough for the colour molecules to sneak inside. This means a demi-permanent will last a bit longer (usually up to 24 washes) but is still a much lower-commitment option than a permanent dye, which goes deep into the hair’s core.
