You dye your hair, choose the perfect shade, invest time and money… and within days, that vibrant colour starts to fade. You wonder: What am I doing wrong?
The answer often lies in something as simple as the water you shower with.
In this article, we explain why shower water can ruin hair colour, which components of the water are responsible, and how you can easily prevent it without giving up dyeing or changing your habits.
What’s in Tap Water That Affects Hair Dye
Your shampoo might be designed for coloured hair, but if the water isn’t right, it won’t help much. Most of the water we use at home contains substances that damage both hair and colour.
Minerals such as Calcium and Magnesium
In areas with hard water, there is an excess of minerals such as calcium and magnesium. These elements build up on the hair, creating an invisible layer that prevents the colour from penetrating properly.
They can also accelerate colour fading, leaving hair looking dull or even causing greenish tones in lighter hair.
Chlorine and Other Chemicals
Chlorine is another major culprit. It is added to disinfect water, but in hair it acts as an oxidising agent, drying out the hair fibre and breaking down the colour, especially in blond, red, and fantasy shades.
Quick Tip: If your dye loses intensity in just a few days or changes shade, the shower water is probably to blame.
Visible Effects on Hair Colour
Here are clear signs that your shower water is affecting your hair colour:
- Rapid loss of colour intensity
- Unwanted tones (green, orange, yellow)
- Rougher or drier texture after washing
- Feeling like the dye “doesn’t hold” properly
If you notice several of these effects, it’s time to take action.
How to Protect Your Colour
Fortunately, protecting your dyed hair is easier than you think. You don’t need to stop showering or wash your hair with bottled water. You just need to tackle the problem at its source: the water.
Use Specific Shower Filters
Tappwater shower filters, such as the ShowerPro or ShowerPro Diamond, remove minerals, chlorine, and other compounds that damage hair. What does this achieve?
- Maintains colour intensity for longer
- Prevents unwanted changes in tone
- Reduces dryness and increases shine
- Saves money on colour-touch products
They are easy to install and fit most showers. No tools or technical skills required.
Colour-Protecting Products
You can also complement with shampoos and masks designed for dyed hair. But remember: if your water still contains chlorine or calcium, no product will be 100% effective. Start by improving the water, and you’ll see real results.
