Every hairdresser has seen it.
A client walks into the salon complaining that their hair suddenly feels dry, dull, difficult to manage or that their colour doesn’t seem to last as long as it used to.
The first questions are usually about shampoo, conditioner, heat styling and colouring history.
But increasingly, another question is entering the conversation:
“What is your shower water like?”
While shampoos and styling products are important, they are only part of the picture. Every time you wash your hair, it comes into contact with the water flowing from your shower. Depending on where you live, that water may contain different disinfectants, minerals and naturally occurring elements that can influence how hair feels and behaves.
Water Isn’t the Same Everywhere
Many people assume tap water is identical across Australia.
In reality, water chemistry can vary between cities, suburbs and even neighbouring streets depending on the source of the water, treatment methods and local plumbing infrastructure.
Some areas use chlorine, while others use chloramine as the primary disinfectant. Mineral levels also differ depending on where the water originates.
These differences don’t necessarily make one water supply better or worse—they simply mean your hair may respond differently depending on where you live.
Why Hair Professionals Notice These Changes
Hairdressers often spend more time examining hair than anyone else.
They see how hair responds after colouring, bleaching, chemical treatments and everyday washing.
Many professionals also notice that clients who move interstate—or even to a different suburb—sometimes describe changes in how their hair feels.
Some common comments include:
- “My hair feels drier than before.”
- “It doesn’t feel as soft.”
- “My colour fades faster.”
- “It takes more conditioner to manage.”
- “It feels heavier or harder to style.”
While many factors can contribute to these experiences, shower water is one that is often overlooked.
What Does the Research Say?
Research has shown that some aspects of water chemistry can influence the properties of hair.
For example, hard water minerals may leave deposits on the hair surface, while disinfectants such as chlorine have been studied for their effects on the hair fibre.
Scientists continue to investigate how different water characteristics affect hair texture, colour-treated hair and the overall condition of the hair shaft.
As research grows, many people are becoming more interested in the role shower water may play as part of an overall hair care routine.
Looking Beyond Hair Products
Healthy hair isn’t just about choosing the right shampoo.
Hair professionals often consider many factors, including:
- Nutrition
- Heat styling
- Chemical treatments
- Sun exposure
- Swimming
- Hair care routines
- The water used every day
Considering shower water alongside these factors can help create a more complete approach to hair care.
The Future of Hair Care
As awareness continues to grow, more Australians are asking questions about the water they use every day.
Understanding your local water supply and choosing products that suit your hair type—including shower filtration where appropriate—may become an increasingly common part of modern hair care.
After all, if every wash starts with water, it’s worth understanding what is flowing through your shower.
