You walk out of the salon after having a colour done, with a million-dollar smile on your face. The colour is glossy, rich and exactly what you pictured.
But the real pain begins when the hair colour becomes dull just after a few washes.
Hair colour fades fast because colour molecules slowly escape through a raised or damaged hair cuticle. Don’t worry, we’ll explain this phenomenon later in the blog.
Just to make things simple, keep in mind that frequent washing, hot water, harsh shampoos, heat styling, sun exposure and quality of the hair dye all of them can cause the hair colour to fade away early. Moreover, some shades, especially red and copper, are naturally quicker to fade.
The good news is that most of these causes are within your control. Let’s break down what is really happening and how to fix it.
How Hair Colour Actually Works
Think of each hair strand like a pinecone. The outer layer, the cuticle, is made of overlapping scales. Underneath that, there is the cortex, the inner part of the hair shaft where colour lives.
Professional colour gently lifts those scales so colour molecules can move inside. Once they settle, the cuticle closes and holds them in place. Fading happens when those scales open again and pigment slips out a little more each time.
Not every formula holds on equally:
- Permanent hair colour penetrates the cortex and lasts longest.
- Demi-permanent colour and toners sit closer to the surface, so they soften within weeks.
- Semi-permanent dye and fashion colours mostly coat the outside, which is why vivids wash out quickly.
- Temporary hair colour lasts until your next shampoo.
7 Reasons Your Hair Colour Fades Quickly
1. Frequent Washing
Every wash swells the hair with water and lifts the cuticle slightly. More washes means there are more chances for pigment to escape. If your hair colour fades after a few washes, your shampoo routine is the first place to look at.
2. Hot Water
Hot showers feel lovely, but heat opens the cuticle wider and lets colour rinse straight down the drain. Wash in lukewarm water and finish with a cool rinse.
3. Harsh Cleansing Products
Many everyday shampoos contain strong sulphates designed to strip oil, and they strip colour along with it. Clarifying shampoo is even tougher, so keep it for rare occasions rather than the weeks after a colour appointment.
4. Damaged and Porous Hair
Does damaged hair make colour fade faster? Absolutely.
Bleached hair and other chemically processed hair often have chipped, uneven cuticles. That creates high porosity, so hair soaks up colour quickly but struggles to hold it. It is a bit like filling a leaky bucket, and you’ll usually notice it on the ends first.
5. Heat Styling
Straighteners and curling wands run seriously hot. Without protection, that heat weakens the cuticle and cooks the tone out of your colour. Blondes most of the time turn yellow, while brunettes and reds lose their richness.
6. The WA Sun
UV rays break down colour pigments much like they fade a beach towel left outside. Perth has high UV levels for much of the year, and the Bureau of Meteorology’s Perth UV forecast shows daily sun protection times worth checking before a long day outdoors.
Add chlorine and saltwater from the pool or the beach, and your colour takes a double hit.
7. Hard Water Minerals
Calcium and magnesium can build up on hair and leave colour looking flat. The Water Corporation notes that hard water is more common in parts of regional WA supplied mainly by groundwater. If you live outside the metro area and your colour dulls quickly, minerals may be adding to the problem.
Why Does Red Hair Fade the Fastest?
Red hair colour has a reputation for disappearing, and it’s well earned.
Red dye molecules are generally larger than other shades, so they don’t anchor as securely inside the hair and escape more easily with each wash. Copper hair colour behaves the same way, and vivid hair colour fades even faster because most of it sits on the surface.
If you’re a redhead, treat your colour like a delicate fabric. Wash less, rinse cooler and use a colour-depositing conditioner between appointments.
Fading vs Brassiness
Why is my hair colour turning brassy? Usually because your blonde toner has worn off.
Lightening exposes natural warm pigments underneath, and toner neutralises them. As toner fading happens, those unwanted warm tones of yellow and orange come through. So brassiness doesn’t mean your colour has failed. Often it just needs a toner refresh.
How Long Does Hair Colour Last?
| Colour type | Average lifespan | What fades first | Best maintenance move |
|---|---|---|---|
| Permanent colour | Shade holds, regrowth shows in 4 to 8 weeks | Shine and richness | Colour-safe routine plus a gloss between visits |
| Demi-permanent and toners | Around 4 to 6 weeks | Tone, so blondes warm up | Purple shampoo once a week, regular toner top-ups |
| Reds and coppers | Often softens within 2 to 4 weeks | Vibrancy, especially on the ends | Cool rinses and colour depositing conditioner |
| Vivids and fashion colours | Roughly 2 to 6 weeks | Brightness with every wash | Stretch washes as long as possible |
| Colour on bleached or porous hair | Shorter than on healthy hair | Ends, where damage is greatest | Repair treatments and deep conditioning |
(These are average ranges. Your results depend on hair condition, routine and lifestyle.)
How to Make Hair Colour Last Longer
Here’s how you can maintain hair colour between appointments.
- Wait before your first wash. Give colour 48 to 72 hours to settle before shampooing.
- Switch to colour-safe products. A sulphate-free shampoo and colour-safe conditioner cleanse gently without dragging pigment out.
- Wash two or three times a week. Wondering how often to wash coloured hair? Most people can stretch to every second or third day, with dry shampoo filling the gaps.
- Always use a heat protectant spray. Apply it before every blow-dry or straightening, and lower your tool temperature where you can.
- Protect against the Aussie sun. Wear a hat, or use a leave-in with UV protection for hair on beach days.
- Prep before swimming. Wet your hair with fresh water and add leave-in conditioner first, so it absorbs less chlorine and salt.
- Use a deep conditioning hair mask weekly. Hydrated hair keeps a smoother cuticle, which improves colour retention.
- Book toner top-ups and colour refresh appointments. A quick gloss every 6 to 8 weeks revives dull colour without a full recolour.
Choose a Technique That Fades Beautifully
How your colour is placed changes how noticeable fading becomes. Soft, blended placements grow out more gracefully than solid, high contrast colour. If low maintenance matters to you, it’s worth understanding the difference between balayage vs foils before your next appointment.
Smoother hair also holds colour better, which is why some clients pair colour with a keratin treatment. Timing matters here, because colouring within two weeks after keratin can lead to fading. Plan both services together with your stylist.

FAQs
Does purple shampoo fade blonde hair colour?
No. Purple shampoo deposits violet pigment that neutralises yellow tones. Overusing it can leave blonde looking dull or lilac, so once a week is usually enough.
How soon can I swim after colouring my hair?
Wait at least 72 hours so the cuticle can fully close. For the first couple of weeks, rinse with fresh water before and after every swim.
Does dry shampoo make hair colour fade faster?
No. Dry shampoo helps colour last longer by letting you skip washes. Brush it out thoroughly so buildup doesn’t leave your colour looking dull.
Does salon hair colour last longer than box dye?
Generally, yes. A colourist tailors the formula, developer and processing time to your hair’s porosity, while box dye uses one formula for everyone.
Can a toner fix faded hair colour?
Yes. A toner or gloss refreshes faded tone, neutralises brassiness, and restores shine in one short appointment, without the commitment of a full recolour.
