Hard water can play havoc with your hair and skin. It can cause residue and product build up, affecting the health and shine of your hair, as well as making your skin feel dry and irritated. But short of moving to a soft water area, what can you do about it?

 

The solution could be simpler than you think. A shower filter is a game-changing bathroom upgrade that can make all the difference when it comes to the quality of your showers. Read on to find out how.

What Is Hard Water and Why Does It Matter for Your Shower?

You may see the effects of hard water in your shower cubicle (usually in the form of white chalky deposits on glass and tiles). But you might not know what hard water actually is. 

 

Here’s an explainer - hard water contains high levels of minerals such as calcium and magnesium. These are picked up from limestone and chalk as rainwater makes its way into reservoirs and into the mains water system. Hard water is particularly common in London and the South East of the UK. 

 

It isn’t dangerous to drink water containing these minerals, but it can affect your daily shower routine. 

 

Hard water can:

 

  • Leave mineral residue on skin and hair
  • Make shampoo and soap harder to rinse away
  • Cause dryness and irritation
  • Contribute to frizzy, brittle hair
  • Create limescale buildup on showerheads and tiles.

 

These issues can build up over time, and can be really frustrating to live with. You may struggle to feel properly clean after showering, no matter what products you use.

Is Hard Water Bad For Your Skin and Hair?

Hard water effects can be annoying for everyone, but they’re particularly problematic for people who already have dry hair or sensitive skin. 

 

This is because the minerals in hard water can disrupt the skin barrier (including on the scalp) and leave behind residue that prevents proper hydration. 

 

It can worsen existing issues with dryness, and irritation, and even trigger flare-ups of conditions such as eczema and psoriasis. Skin can feel tight and itchy, while your hair can suffer from dullness and frizz - or it can feel weighed down with mineral buildup. If you have coloured hair, you may notice it fades more quickly, while blonde hair can end up brassy or yellow.

 

Lastly, there’s your scalp. It can become dry and flaky after repeated exposure to hard water, and existing problems with dandruff can be exacerbated. 

Do Hard Water Shower Filters Work?

So the big question is - do shower head filters work for hard water, and can they alleviate all of these problems? 

 

In short, yes. A good shower filter can improve water quality, purify your water and give you back the clean, fresh feeling you used to have after showering. This means hair and skin products that actually work (and rinse away properly), no residue buildup and no unnecessary flare-ups. 

 

Shower filters work in a simple yet surprisingly effective way. They replace your normal shower head (usually in a few simple steps, without the need for a plumber) and intercept the flow of water before it reaches your hair and skin. 

 

The filter inside catches minerals, chlorine, heavy metals, sediment and other contaminants in your water, trapping them inside the filter. Change the filter regularly and it’ll be just like you live in a soft water area. 


For most people, this means a noticeable improvement in hair and skin health. You’ll enjoy healthier-looking hair, softer skin, and less dryness and irritation. Your shower should also stay cleaner, as there’ll be reduced limescale buildup on tiles, glass and surfaces.
