I love this shower head! The water feels amazing, and it was super easy to install. I’ve already noticed my hair looks way healthier and my skin isn’t as dry anymore. It’s such a small change that has made a huge difference!! Totally worth it.

Honestly, this is an absolute game changer for me. I’ve always struggled with dry skin on my face, have tried products that haven’t fixed it long term. Finally, since I started using filtered water with this shower head I’m actually seeing improvements! My hair is also feeling softer and healthier. Can’t recommend this product enough.

Sia has done absolute wonders for my skin and hair, I have been using for a few weeks now and I can really notice a difference. Not only that the design is extremely sleek and the installation was so easy! I now know that my water is inherently cleaner making me feel much better after every shower. Also a bonus it has improved my water pressure!

Our skin feels better and my normally dry tight scalp feels so much calmer. Our hair has benefited too so win win!! I hadn’t subscribed straight away because I wanted to give it a go first, but, pretty much, 3 months later the yellowing on our shower curtain started again. I instantly subscribed and am so pleased I did! Thanks Sia.

This shower head has made such a difference for me! Normally during the winter I tend to get drier skin and a drier scalp, but since installing this shower head, I have noticed a big improvement. My skin feels more hydrated, and my hair feels less brittle. It also brings peace of mind to know that it is filtering out any harmful chemicals. I would recommend this to everyone!

I’ve noticed a huge difference in the hard-water build-up in my bathroom. My shower curtain and bathroom tiles aren’t going orange anymore and my hair/ skin look and feel so much better!

Your Week-by-Week Results

    First Few Showers

    Immediate feel-good changes

    • You may notice your skin feels less tight and smoother immediately after showering, as the chlorine is no longer stripping its natural oils.
    • The natural moisture balance is preserved, so your skin stays hydrated for longer and feels more comfortable throughout the day.
    • Many people also find that dry patches soften and any feelings of itchiness or sensitivity begin to ease almost right away.

    Within 1–2 Weeks

    Softer skin & easier hair

    • Softer, smoother skin: Skin retains moisture better, leading to a more hydrated and supple feel, according to a study where 63% of people reported better skin moisture after two weeks with filtered water.
    • Less irritation: Reduced exposure to harsh chemicals and minerals can lessen scalp itchiness and skin dryness.
    • Improved hair texture: Hair becomes softer, smoother, and more manageable, making it easier to brush and style.

    Ongoing Benefits

    Long-term skin & hair health

    • Healthier scalp: A healthier scalp supports hair growth and can help prevent dandruff.
    • Reduced breakouts: Filtering out bacteria and impurities helps keep pores clearer, which can reduce acne and other skin issues.
    • Longer-lasting hair colour: Filters can protect colour-treated hair from being stripped by harsh chemicals.
    • Calmer sensitive skin: For conditions like eczema or dermatitis, filtering out impurities can help reduce flare-ups and provide relief.

Our multi-stage shower filtration system combines premium natural and engineered media to deliver cleaner, softer, healthier water:

  • KDF-55: Chlorine & heavy metal removal
  • Vitamin C: Chlorine/chloramine neutralization
  • Carbon: Odor & chemical adsorption
  • Calcium Sulphite: Fast chlorine removal

This depends on your water quality and how often you use your shower. As a guide, most people replace their filters every 3–6 months. Regularly changing the filter ensures your shower head continues to reduce chlorine, limescale, and other impurities, keeping your skin and hair feeling their best.

Yes. Many customers notice softer skin, shinier hair, and a fresher overall feeling after switching. By reducing harsh chemicals and minerals, filtered shower heads create a more spa-like experience at home — proof that small changes can have a big impact on your wellbeing.

They are designed with sustainability in mind. Using advanced flow technology, our shower heads deliver strong water pressure while using less water overall. That means you get a powerful, refreshing shower while saving on your bills and reducing your environmental footprint.

Keeping your shower head clean is simple. Wipe the outside with a soft, damp cloth, and every so often soak the nozzles in a little warm water with vinegar to clear any limescale. This keeps your shower working at its best and ensures your water feels fresh and smooth.

Very easy. All of our shower heads are designed for simple, tool-free installation. Just unscrew your old shower head, attach the new one, and you’re ready to enjoy your upgraded shower in minutes.
