Every shower you take exposes your skin and hair to chlorine, heavy metals, and hard water minerals — unless you filter it first.HolyH2O™ Shower Plus Review: What It Does, How It Works, and Why Your Shower Water Matters More Than You Think
Most Australians spend hundreds of dollars on skincare serums, shampoos, and hair treatments — and never think about the water those products are rinsing off in. But every time you shower, your skin and hair are exposed to chlorine, chloramines, heavy metals, and hard water minerals from the municipal water supply. These aren't trace amounts you can ignore. Dermatologists have documented their effects. And no moisturiser or conditioner fully compensates for what chlorinated water strips away at the source.
The HolyH2O™ Shower Plus is a premium multi-stage inline shower filter designed to remove up to 95% of chlorine and chloramines, filter heavy metals, soften hard water, and infuse beneficial minerals — all without a plumber, without tools, and in under 60 seconds of setup. This guide covers exactly what it does, the science behind why shower water quality matters, and who it's best suited for.

Myths vs. Facts About Shower Water
Before getting into the product itself, here are the most common misconceptions that stop people from taking shower water quality seriously.
❌ Myth 1
Shower water doesn't affect your health — you're not drinking it.
✅ Fact
Your skin is your largest organ and it absorbs what it's exposed to. Multiple studies show chlorine is absorbed transdermally during showering — and hot water opens pores, increasing absorption. Chlorine also vaporises into steam, meaning you inhale volatile chlorine compounds throughout your shower. Research published in the American Journal of Public Health found that showering can be a greater source of chlorine exposure than drinking chlorinated water.
❌ Myth 2
If my hair and skin are dry, it's my shampoo or genes — not my water.
✅ Fact
Chlorine strips the natural sebum layer from your scalp and skin, disrupting the protective oil barrier that keeps moisture in. Hard water minerals (calcium and magnesium) deposit on hair shafts and skin, compounding the dryness. Many dermatologists now recommend shower filtration as a first-line recommendation for patients with persistent dry skin or scalp conditions before adjusting product routines.
❌ Myth 3
Shower filters reduce water pressure significantly.
✅ Fact
Well-engineered shower filters like the HolyH2O™ Shower Plus are designed to maintain full flow pressure. The filtration media is sized to allow normal water volume to pass through without restriction. Most users report no noticeable difference in shower pressure after installation.
❌ Myth 4
A shower filter is a luxury, not a necessity.
✅ Fact
If you live in any Australian capital city, your water is chlorinated. This is non-negotiable for public health — but it also means every shower is a chlorine exposure event. For people with sensitive skin, eczema, psoriasis, colour-treated hair, or anyone spending money on premium skincare, a shower filter is arguably a higher-return investment than most of the products in their bathroom cabinet.
What Chlorine and Hard Water Are Doing to Your Skin and Hair
Understanding the problem makes the solution obvious. Here's what's happening every time you shower in unfiltered Australian tap water:
To Your Skin
- Strips natural oils: Chlorine is a powerful oxidant that breaks down the lipid layer protecting your skin, causing dryness, tightness, and accelerated visible ageing
- Disrupts the skin microbiome: The beneficial bacteria that protect your skin barrier are killed by chlorine, leaving your skin more vulnerable to breakouts, irritation, and sensitivity
- Triggers eczema and psoriasis flare-ups: Multiple peer-reviewed studies link chlorine exposure in shower water to worsening of inflammatory skin conditions, particularly in children
- Causes acne: With protective sebum stripped, pores become more susceptible to clogging and irritation, contributing to breakouts especially on the back and chest
- Chloroform inhalation: Chlorine in hot shower steam converts to chloroform, a compound classified as a possible human carcinogen, which you inhale throughout the shower
To Your Hair
- Raises the hair cuticle: Chlorine forces the overlapping cuticle scales open, leaving hair porous, dry, and prone to breakage and frizz
- Strips colour up to 70% faster: Colour-treated and bleached hair is particularly vulnerable — chlorine actively degrades the dye molecules in your hair shaft
- Creates mineral build-up: Hard water calcium and magnesium deposits accumulate on hair shafts and around follicles, contributing to hair thinning, shedding, and brittleness
- Scalp irritation and dandruff: Removing protective sebum from the scalp creates the dry, flaky conditions that cause dandruff and itchiness that no shampoo fully resolves while the root cause remains
🔑 The key insight: No amount of conditioner, serum, or moisturiser fully compensates for daily chlorine exposure if the source isn't addressed. The most effective thing you can do for your skin and hair routine is change what your water is doing to you before any product touches your skin.
How the HolyH2O™ Shower Plus Works
The Shower Plus is an inline shower filter — it connects directly between your existing wall outlet and your showerhead. No plumbing, no drilling, no tools. It installs in under 60 seconds and works immediately from your very first shower.
Inside the Shower Plus is a multi-stage filtration system that works in sequence on every litre of water that passes through:
The primary filtration stage uses KDF-55 media — a high-purity copper-zinc alloy that removes free chlorine through an electrochemical oxidation-reduction process. Unlike activated carbon (which degrades in hot water), KDF-55 performs effectively at shower temperatures and is NSF/ANSI-certified for chlorine reduction.
The same KDF media captures lead, mercury, iron, and other heavy metals through precipitation and ion exchange. This is particularly relevant for homes built before 1990, where lead can leach from older pipes between the street main and your showerhead.
The Shower Plus includes scale-reducing media that soften hard water by reducing calcium and magnesium mineral content. This prevents the mineral deposits that build up on hair shafts and skin surfaces, and is responsible for the noticeably softer skin feel many users report within the first few showers.
Unlike basic chlorine-only filters, the Shower Plus adds back beneficial minerals and vitamins that nourish the skin and scalp with every shower. This is the stage that distinguishes the Shower Plus from lower-tier shower filters and is a key reason users report skin and hair improvements beyond simply removing what was harmful.
Municipal tap water in most Australian cities has a pH between 7.0 and 8.5 — mildly alkaline, but still higher than the skin's natural pH of around 4.5–5.5. The Shower Plus helps moderate the pH of water contacting your skin, reducing the alkaline disruption to your skin's acid mantle that contributes to dryness and sensitivity.

What You'll Actually Notice — and When
Based on customer feedback across 100,000+ HolyH2O™ customers, here's a realistic timeline of what to expect:
days
The most immediate change most users notice is the absence of that faint pool-like chlorine smell during and after their shower. This happens from the very first use.
days
Within the first week, most users report that their skin feels softer and less tight after showering — without applying more moisturiser. This is the combined effect of chlorine removal and hard water softening.
weeks
As mineral deposits on hair shafts begin to clear and chlorine damage stops accumulating, hair typically becomes shinier, smoother, and more manageable — especially noticeable for curly, wavy, or colour-treated hair.
weeks
For those with eczema, psoriasis, or persistent acne, improvements in flare frequency and severity typically become noticeable within 2–4 weeks as the daily chemical trigger is removed. Results vary by individual and condition severity.
weeks
With mineral build-up around follicles clearing over time, many users report a reduction in daily hair shedding. This is one of the slower-developing benefits as it requires accumulated mineral deposits to clear from the follicle level.
Who Needs the Shower Plus Most
The Shower Plus is a meaningful upgrade for almost every Australian household — but it delivers the most noticeable results for:
🎯 Best-Fit Users for the HolyH2O™ Shower Plus
- People with dry, sensitive, or reactive skin — including those who've tried multiple moisturisers without lasting results
- Eczema, psoriasis, or dermatitis sufferers — chlorine is a documented trigger for inflammatory skin conditions
- Anyone with colour-treated or bleached hair — chlorine strips colour up to 70% faster, making this a cost-saving measure as much as a health one
- People experiencing hair thinning or excessive shedding — especially where hard water is a contributing factor
- Curly or wavy hair types — chlorine and hard water are particularly damaging to curl definition and moisture retention
- Families with young children — children's skin is thinner and more permeable, making chlorine absorption proportionally higher
- Anyone spending significant money on premium skincare or haircare — you're working against yourself if your water is undoing what your products do
- Renters who can't modify plumbing — the Shower Plus requires no permanent installation and is fully portable

🔑 Our recommendation: For most Australians wanting meaningful skin and hair improvements, the Shower Plus is the right starting point. It covers all five filtration stages including mineral infusion and pH balancing that basic filters omit. The Shower Max suits larger households or areas with noticeably harder water or stronger chlorine odour.
Installation and Maintenance
The Shower Plus installs in three steps, no tools required:
Simply unscrew your current showerhead from the wall outlet by hand. Most Australian showerheads unscrew easily — if stiff, use a cloth for grip rather than a wrench to avoid thread damage.
Thread the Shower Plus filter body clockwise onto the wall outlet. Hand-tighten firmly — no tools needed. The unit includes universal thread sizing compatible with all standard Australian shower fittings.
Thread your existing showerhead onto the outlet end of the Shower Plus. Turn on the water and check for any leaks at both connections. Done — your next shower is filtered.
🗓 Shower Plus Maintenance Schedule
- Every 3–6 months: Replace the filter cartridge — performance gradually decreases as filtration media becomes saturated, typically around 10,000–15,000 litres
- Watch for signs it's time to replace: Return of chlorine smell, reduced water softness, or change in water taste if drinking is involved
- Replacement cartridges: Available directly from HolyH2O™ at holyh2o.com.au with free express shipping
- No other maintenance required: No cleaning, no backflushing, no descaling of the filter body itself
Frequently Asked Questions
Does the HolyH2O™ Shower Plus fit Australian shower fittings?
Yes — the Shower Plus is designed specifically for standard Australian shower connections and is compatible with all standard fixed and handheld showerhead configurations. It installs without tools in under 60 seconds.
Will it reduce my water pressure?
No. The Shower Plus is engineered to maintain full water pressure throughout filtration. The vast majority of users notice no change in shower flow after installation.
How often do I need to replace the cartridge?
Every 3–6 months, depending on your household's daily usage and local water quality. Replacement cartridges are available from HolyH2O™ with free express shipping Australia-wide.
Can it help with eczema or psoriasis?
Many users with eczema and psoriasis report a reduction in flare frequency and severity after switching to filtered shower water. Chlorine is a well-documented trigger for inflammatory skin conditions. While results vary, removing the daily chemical trigger is a logical and commonly recommended first step by dermatologists.
Can a shower filter help with hair loss?
Hard water minerals deposit around hair follicles, restricting healthy growth and contributing to breakage and daily shedding. By removing these minerals and chlorine, the Shower Plus addresses a major and commonly overlooked contributor to hair thinning.
What's the difference between the Shower Plus and the Shower Mate?
The Shower Plus is HolyH2O's premium 5-stage shower filter, adding mineral and vitamin infusion and pH balancing on top of the 3-stage chlorine, heavy metal, and sediment filtration of the Shower Mate. For users focused on skin and hair improvement — rather than just chlorine removal — the Shower Plus is the recommended option.
Is there scientific evidence that shower filters improve skin and hair?
Yes. Multiple peer-reviewed dermatological studies link chlorine and hard water exposure in shower water to increased skin dryness, eczema flare-ups, and structural hair damage. A 2018 study published in the International Journal of Trichology found a significant association between hard water and hair breakage. Removing chlorine and softening water has been demonstrated to measurably reduce these effects.
Is the Shower Plus suitable for renters?
Yes — the Shower Plus requires no permanent installation, leaves no marks, and is fully reversible. It's ideal for renters who can't make plumbing modifications but want the full benefit of filtered shower water.
💡 Pro Tip: Pair It with the Trinity
