Expert Insight
Dr Sonia Khorana is a UK-based GP with a special interest in dermatology, known for her evidence-based, practical approach. She treats a wide range of skin and scalp concerns and highlights water as an often-overlooked trigger in everyday routines.

“My patients rarely think of water when their skin flares up, but they should.”

Hard water is rich in calcium and magnesium. These minerals leave a residue on your skin that raises its pH, making it more alkaline. Your barrier functions best around 5.5, so this shift can weaken its natural defences. Over time, this can lead to dryness, tightness, irritation, and increase the risk of eczema.

“Hard water changes how your products work.”

Minerals like calcium and magnesium react with cleansers to create soap scum, leaving a filmy residue on skin, scalp, and surfaces. This buildup blocks moisture, weighs hair down, and makes products less effective over time.

“Chlorine accelerates moisture loss, leaving skin feeling tight.”

For sensitive or eczema-prone skin, this irritation compounds over time, making flare-ups more frequent and recovery slower.

“Heavy metals in water are invisible but impactful.”

Trace metals like copper and iron, often found in older pipes, can deposit on skin and scalp. These invisible particles contribute to oxidative stress and interfere with how your skincare and haircare perform. This build-up can explain why some skin feels persistently dry, congested, or irritated even with a consistent routine.

A water softener is a whole-house device that tackles limescale, but it doesn’t address everything. While no shower filter removes calcium and limescale, our Hello Klean Filtration range targets harmful elements like iron, copper, lead, and chlorine, helping to mitigate the harsh effects of hard water on your skin and hair. But we don’t stop there—our wash-off products are powered by our proprietary Klean Complex, specifically designed to combat the lingering effects of calcium and magnesium.

The Klean Complex works by neutralising these stubborn minerals, preventing them from clinging to your hair and skin. For your hair this means less crispy-feeling, reduced breakage and restored fullness. For your skin, this means boosted moisture, and reduced irritation to help maintain a healthy skin barrier.

Together, our haircare, bodycare and filtration range offer a comprehensive solution, addressing both the water you shower in and the lasting impact it can have on your hair and skin. This dual-action defense ensures you step into the shower and out so your hair and skin can get back to how it used to be.

No, our Hello Klean Filtration range won’t affect your water temperature. The filters are designed to maintain your water's flow rate and pressure, ensuring that your water temperature remains consistent during your shower.

You don't need a handyperson, electricity to install our shower filter, rain shower or shower head. It's designed for quick and easy setup.

Yes, our Hello Klean Filtration range is compatible with electric heaters and can be installed without issue. However, because different heaters have varying flow requirements, we recommend checking with your heater's supplier or manufacturer beforehand to ensure optimal performance. This way, you can be sure everything works smoothly together.
