Uncover what’s really flowing from your shower and how filtering your water with Hello Klean could be the answer to glowing skin and happy hair
Have you ever stopped to think about what’s actually in your shower water? It may look crystal clear, but looks can be deceiving. The truth is, our everyday water often contains a wide range of common water contaminants that could be impacting your skin, hair and even long-term health. Since knowledge is power, we take a closer look at what’s really in your water and why you should strongly consider a Hello Klean water filter…
So, what’s in your water?
You might assume the water coming out of your shower is clean and harmless, but the truth is, it’s often riddled with common water contaminants that affect much more than just its taste. One of the most widespread and underestimated issues? Hard water. Hard water is water that has a high mineral content - particularly calcium and magnesium.
But hard water isn’t the only concern. Your shower may also contain other water contaminants such as heavy metals like lead, mercury and arsenic which are often found in older plumbing systems. Other culprits include pesticides and herbicides from agricultural runoff, microplastics and chlorine.
Even if your water is technically deemed as ‘safe’, hard water and other contaminants can lead to a whole host of issues around the home and also have a pretty big impact on your skin and hair.
The effect of hard water on your skin and hair
While you might not see it, the water you shower in could be leaving more than just steam behind. Hard water can in fact quietly interfere with your skin and hair health. Over time, these minerals accumulate and can leave behind a residue which affects how your skin feels, how your scalp behaves and even how well your products perform.
“Hard water can also increase the pH levels of your skin, making it more alkaline,” explains Dr Sonia Khorana, GP, dermatology expert and Hello Klean ambassador. “The skin barrier functions best at a slightly acidic pH (of around 5.5). A higher pH weakens the skin's defence mechanisms.” This can lead to tightness, flaking, and even flare-ups of eczema and psoriasis - especially in sensitive skin types. “People living in areas with hard water often have drier, rougher skin and sometimes even a general feeling of tightness after washing,” she adds.
That chalky residue can lead to dullness, dryness, and even brittleness of your hair too - particularly those with colour-treated or chemically processed hair types. As hard water accumulates on the scalp, it can lead to itching, flaking, and even clogged follicles that stunt hair growth.
“Filtering water, especially for the shower, is definitely becoming a popular and dermatology-approved strategy for sensitive skin, eczema, and dryness,” explains Dr Sonia who’s seen patients report less dryness, reduced itching, fewer flare-ups, and even better hair texture after switching to using a water filter.
Why you need a water filter at home
We often don’t think twice about investing in serums, creams and shampoos, but we rarely stop to question the water we rinse them off with. Since that water may be the hidden factor sabotaging your routine, a water filter should be top of the list for your next Healf haul.
“The inspiration for Hello Klean came from personal experience,” says Founder, Karlee Zhang. “I’ve lived in many cities where each has different water qualities, and I noticed the way hard water could wreak havoc on my hair and skin. From dull, brittle hair to itchy, dry skin, it was clear that the water itself was the hidden culprit behind these issues.” This insight is what led to the development of their products - a solution designed to target the root cause of these problems, not just the symptoms.
Hello Klean filters use a multi-layered filtration system combining activated carbon and KDF (a redox filtration media). This powerful pairing removes over 90% of chlorine, reduces heavy metals and filters out impurities that harm your skin and hair. Since KDF binds heavy metals during hot showers (when your skin is most absorbent), you’re protected when you need it most.
The importance of clean water goes beyond just appearance. Removing contaminants like chlorine, copper, iron and microplastics helps maintain your skin’s barrier, improves the way your products absorb and protects your scalp and hair follicles from daily stressors.
There’s also the eco-friendly water filter angle. Hello Klean’s filters are all refillable, recyclable and designed to last. They even reduce water usage, lowering your average shower output from 12 litres per minute to just 8.5 litres or 6 litres with their Rain Shower Head.
How to use Hello Klean
Super simple and easy to use, each and every one of their products is intuitive and effective making your water filter setup seriously straightforward.
Simply unscrew your existing shower head and install your Hello Klean Shower Filter in between the pipe and the head. With no tools required, just better water, instantly. Refills are just as easy to replace and worth doing every 3-4 months depending on usage. Once installed, your filter works immediately to soften hard water, reduce chlorine and neutralise metals. The result? Softer, smoother skin, shinier and more manageable hair, less itching, dryness and irritation and better product absorption. We’re sold.
