Does Hello Klean reduce limescale?

And is it the game-changer for your hair and skin you’ve been searching for?

Live in a hard water area and wondering if Hello Klean actually reduces limescale? The short answer: yes — to a degree.

Is your hair frizzy, brittle, or have you noticed your colour fades faster than it should? Does your skin feel tight and dry when you step out of the shower, or have you noticed eczema flair ups? The problem might be flowing straight from your showerhead. If you live in a hard water area, the minerals in your water could be the reason why your skin and hair aren't feeling in top shape.

While hard water isn’t harmful to drink, it can be a nuisance for your hair and skin. That’s where shower filters like Hello Klean can help. So the big question is: does Hello Klean actually make a difference? Let’s dig in

Why hard water can be a problem

You see the way the minerals cling to your shower head? It’s also doing the same thing to your skin and hair and breaking down it’s natural moisture. Hard water is full of minerals like calcium and magnesium. Great for your body when you drink them — not so great when they’re left clinging to your skin and hair. Many people in hard water areas notice that their skin feels dry or tight after a shower, and their hair becomes brittle, frizzy, or harder to manage and that hair colour fades fast.

Emily a hairdresser at Bournemouth, says: “I noticed when I moved from up north to the south how much more quickly highlights dulled and hair texture changed in the south, including my own! I realised it was due to the water hardness in the area. Installing a shower filter in hard water areas is a great way to keep your hair smoother and colours longer lasting.”

How does the Hello Klean filter work?

If you’ve spent some time in Cornwall, Devon, further north or in Scotland where the water is naturally softer and noticed how much nicer your skin and hair feels there — that’s the kind of results shower filters are aiming for.

The Hello Klean shower filter uses a mix of filtration materials to reduce some of the harshness of your water.

KDF-55

KDF-55 is a mix of high-purity copper and zinc. It might sound technical, but its job is simple: it helps remove chlorine, heavy metals (like lead and mercury), and control bacteria growth in your water.

It works using something called redox (reduction–oxidation) — basically, it triggers a chemical reaction that changes harmful contaminants into something more harmless. It’s especially good at targeting the things in water that can irritate your skin and damage hair over time.

Calcium sulphite

This is a powerful filtering material primarily used to remove chlorine from water — and it does it very quickly, even in high temperatures. Chlorine is often added to tap water to disinfect it, but it can strip moisture from your skin and hair, and irritate sensitive skin conditions like eczema.

Ceramic beads

Ceramic beads in shower filters can serve different purposes depending on their composition. In Hello Klean’s case, they help with balancing pH levels and reducing impurities like heavy metals, some bacteria, and residual chlorine.

So how does Hello Klean reduce limescale?

While KDF-55, calcium sulphite, and ceramic beads don’t soften water in the traditional sense — meaning they don’t fully remove calcium and magnesium (the minerals responsible for limescale) — they do help reduce its impact.

Calcium sulphite is particularly effective at removing chlorine, even in hot water, which can make your water feel noticeably gentler on the skin. Although it doesn’t eliminate calcium, it helps stabilise the water’s chemistry, which reduces the likelihood of scale forming.

Ceramic beads, meanwhile, can subtly alter the structure of the minerals — often through magnetic or physical interaction — making them less likely to cling to surfaces like your showerhead or your hair.

Together, these help to make your water feel a little gentler. While it doesn’t soften the water in the way a full-home softening system would, it can take the edge off the worst of the effects — especially in the shower, where you feel it most.

What online reviewers say

There’s no shortage of people online sharing their experiences with Hello Klean — and many of them are pretty positive.

Here are a few from Trust Pilot

"It’s made a noticeable difference in my health and the way my hair feels—so much softer and healthier."

"Using this filter has helped my hair—there is no more frizz, and it is so shinny. My skin is super soft, no longer dry, and I need less moisturizer when I get out of the shower."

"After relocating down south I kept having skin flare ups. I’d tried everything to keep it under control but felt like I was on a constant cycle of steroid creams. I tried the shower head and it has changed everything. I no longer have regular flare ups and my skin has became much more manageable"

For full disclosure there are also some negative reviews for the product but these tend to be about that faulty products.

So… should you try it?

If your skin feels dry, your hair’s got a mind of its own, or you’ve got eczema or colour-treated hair that’s fading fast, a shower filter like Hello Klean could be worth trying. For many users, the difference is noticeable — especially after a few weeks of regular use.

Just be aware that it’s not a one-and-done investment. The filter cartridges need replacing every 3–4 months, so it’s something to factor into the cost.

It’s worth bearing in mind the shower filter wont stop limescale completely, so if you’re looking for a more effective solution a water softening system might be for you.
