Chlorine in Your Shower and Bath Water: What It Does to Your Skin and Hair

Most Australians know their drinking water is treated to keep it safe.

But fewer people think about the chlorine they're exposed to every time they shower or take a bath.

If you've ever noticed dry skin, frizzy hair, or that familiar "pool smell" after showering, chlorine may be one contributing factor.

In this guide, we'll explain why chlorine is added to Australian tap water, how it can affect your skin and hair, and the most practical ways to reduce chlorine exposure at home.

Is There Chlorine In Australian Tap Water?

Yes, most Australian municipal water supplies use chlorine or chloramine to disinfect drinking water and keep it microbiologically safe during distribution.

According to the NHMRC Australian Drinking Water Guidelines, disinfectants such as chlorine are used to protect public health by controlling harmful microorganisms throughout the water supply network.

This is a good thing.

The purpose of filtration is not because treated tap water is unsafe to drink.

Instead, many households choose to reduce chlorine because of its taste, smell, or how it affects their skin and hair during daily use.

What Chlorine Can Do To Your Skin And Hair

Although chlorine is effective at disinfecting water, it can also remove some of the natural oils that help protect your skin and hair.

Some people notice:

• Dry skin
• Tight skin after showering
• Itchy skin
• Frizzy hair
• Hair that feels dry or brittle
• Faster fading of colour-treated hair

Sensitivity varies from person to person.

Long, hot showers may increase contact because warm water opens pores and creates steam, increasing exposure during showering.

Research suggests chlorine exposure may contribute to skin dryness and irritation in some individuals, particularly those with sensitive skin.
