The Hidden Effects of Copper in Your Shower Water on Coloured Hair

If you've invested in colouring your hair, you've probably been warned about the usual culprits behind fading:

• UV exposure
• Heat styling
• Harsh shampoos

But there's another factor many people overlook—your shower water.

In many parts of India, water can contain trace amounts of metals such as copper, iron, and other minerals that gradually build up on the hair shaft.

Over time, these deposits can affect the appearance, feel, and longevity of coloured hair.

Why Copper Matters

Research has found measurable levels of copper in hair samples around the world.

While copper occurs naturally in water supplies, it can also enter your shower water through ageing plumbing systems, water tanks, and household pipes.

For colour-treated hair, this matters because copper is highly reactive.

It can accelerate oxidation, contributing to:

• Faster colour fading
• Brassiness and unwanted warm tones
• Dullness and loss of shine
• Increased dryness and rough texture
• Split ends and breakage

The risk is often higher for highlighted, bleached, or lightened hair because the hair cuticle becomes more porous during the colouring process, making it easier for minerals to accumulate.

Signs Copper May Be Present in Your Water

You may notice:

• Blue-green stains around taps or shower fixtures
• A metallic taste in tap water
• Hair colour fading sooner than expected
• Increased brassiness in blonde or highlighted hair
• Hair that feels coated or dull despite regular washing

Can You Remove Copper Build-Up?

A chelating shampoo can help.

Unlike regular shampoos, chelating formulas are specifically designed to remove mineral deposits from the hair.

Many colourists recommend using one every few weeks to reduce buildup and maintain colour vibrancy.

However, prevention is often easier than correction.

Start With Cleaner Shower Water

If your hair never seems to feel as healthy as it does after a salon visit, your shower water may be working against you.

• Sediment
• Chlorine

By filtering water before it reaches your hair, the Pure Flow Shower Head helps create a cleaner environment for colour-treated hair, allowing your shampoos, conditioners, and treatments to perform the way they're meant to.
