Hard, mineral-rich water can be a burden on skin and hair. The PICKI NIKI filtered shower head is engineered for skin and hair contact under shower conditions.

It binds the calcium and magnesium minerals – the culprits behind hard water – helping reduce the residue they leave behind.

Use against hard water: ascorbic acid binds with magnesium and calcium minerals, making them water-soluble. This helps reduce the residue they leave on skin, hair and in the shower cubicle.

The lime, calcium carbonate (CaCO3), combines with ascorbic acid (C5H5O5CH2OH). The product is CO2 (carbon dioxide gas that simply goes into the atmosphere), H2O (water) and Ca(C6H7O6)2 (calcium ascorbate, which is water-soluble).

Use against chlorine: Reduces residual chlorine to non-detectable levels (KEWI lab test).

One gram of ascorbic acid neutralises the free chlorine in roughly 400 litres (about 100 gallons) of water at 1 mg/L. The reaction is very fast.

C5H5O5CH2OH + HOCL → C5H3O5CH2OH + HCl + H2O

Ascorbic acid + hypochlorous acid → dehydroascorbic acid + hydrochloric acid + water

About 2.5 parts ascorbic acid are needed to neutralise 1 part chlorine. Since ascorbic acid is weakly acidic, the pH of the treated water can drop slightly in weakly alkaline water. Slightly acidic water is perfect for the skin barrier, scalp and hair.

Look forward to a change for softer skin, silkier hair and a shower that feels like a gentle waterfall.

The Vitamin C gel filter is built around a small set of functional ingredients.

Ascorbic acid (vitamin C): the active filtration ingredient. It neutralises free chlorine (KEWI 2020 lab) and may reduce the mineral residue that hard water leaves on skin, hair and in the shower cubicle.

Glycerin: a humectant used in the gel formulation.

What Your Shower Becomes

Filter the water, and the difference shows up where you actually feel it - every shower, without changing a single product.

Less Residue Feel

Vitamin C mildly binds calcium - it does not soften the water, but there is less of that residue feel on skin and hair.

Aromatherapy in Every Shower

Fuller-Looking Hair, Less Breakage

Chlorine and hard-water minerals leave hair drier and more brittle, so it snaps and breaks more easily - and over time can start to look thinner and flatter. Take that daily stress away, and hair holds its body and strength better: less breakage, fuller-looking, wash after wash. (Thinning has many causes, including genetics; for medical hair loss, see a professional.)

Softer, Shinier Hair

Hard water leaves a dulling mineral film on every strand that no conditioner fully rinses away. Filter it out, and hair feels the difference from the very first wash - softer, glossier and easier to run your fingers through. The same hair, just without the residue dragging it down.

The Clean Base Your Skincare Needs

You invest in serums and creams - then every shower coats your skin in the chlorine and hard-water minerals they have to fight. Filter the water, and your routine finally has a clean base to work on: skin that looks fresher and more radiant, so the products you already love can actually do their job. Great skin starts with the water you wash in.

Calmer, Less Flaky-Looking Scalp

Chlorine and hard water strip moisture from the scalp with every shower, which can leave it dry, tight and flaky-looking over time. Filtered water lifts that daily burden, so the scalp has room to stay calmer and more balanced - the foundation for hair that looks and feels better. One environmental factor you can actually control.

02 · THE PROBLEM

You Don't Have a Skin Problem. You Have a Water Problem.

Hard water, chlorine and pipe sediment are three things a standard shower head lets straight through - and skin and hair are where you feel it first.

Chlorine

Added to UK tap water to keep it safe, and nothing removes it before your shower. With daily exposure skin can feel drier and hair rougher - and it's the smell in a warm bathroom.

Rust & sediment

Older pipes shed rust and fine particles the naked eye never sees - until you pull the filter out and look. Not in every home, but real where it happens, and a reason to filter.

Day after day, this combination can affect:

Most filters catch one. Not all three.

THE ONE EVERYONE SHARES

Remember How Your Skin Felt After the Pool?

That tight, dry skin. Frizzy, straw-like hair. The chlorine smell that clings even after you towel off. Here's the uncomfortable part: the same chlorine runs through your shower at home - not once on holiday, but every single day.
Chlorinated swimming-pool water
  • Added to keep water safeIn the UK it's added to tap water by law; across most of Europe it's standard practice - and nothing removes it again before it reaches your shower.
  • Safe to drink, hard on skinWith daily exposure, warm chlorinated water can strip the skin's natural oils and dry out hair - 'squeaky-clean-but-tight' isn't clean, it's stripped.
  • You can smell itThat pool-like note in a warm bathroom is the chlorine that's already in your water.

Where You Shower, the Water Runs Hard

60%
of UK homes shower in hard water.

You've seen what it leaves on the glass and the kettle. It's in your shower water too - and it doesn't rinse off your skin and hair any differently.

The Water You Can't See - Until You Pull the Filter

Every sediment filter comes out the same way. This is rust and pipe sediment it caught from a normal home - before it reached your skin.

Straight From a Normal Home

The sediment filter after everyday use on a standard mains supply - this is the rust and pipe sediment it caught before the water reached your skin.

It Comes Out Brown

Not a one-off. Pull the sediment filter on most older plumbing and it looks like this - fine rust and particles you never see in clear-looking water.

Weeks to Months, Depending on Your Pipes

A fresh white filter next to one that's been in use - that colour is pipe sediment. In older plumbing it can brown within days; in modern pipes it stays lighter far longer. Replace it by around two months either way.

03 · SEE IT WORK

See It Clean Your Water - Step by Step

STEP 1: Sediment Filtration

A dedicated 5μm pre-filter catches rust, pipe debris and grit from old plumbing - the coarse stuff most shower filters skip, before it ever reaches your skin and hair.

STEP 2: Chlorine Neutralised on Contact

Vitamin C reacts with free chlorine by redox as water flows through, cutting it to non-detectable (KEWI lab, 2020). Daily chlorine can leave skin drier and hair rougher - filtered water can feel gentler.

STEP 3: Less Visible Hard-Water Residue

The same Vitamin C stage makes calcium and magnesium more water-soluble, so hard-water residue rinses away instead of building up - less visible film on skin and hair. It does not soften your water.

STEP 4: Stronger Spray, Less Water

A 200-hole precision plate gives a stronger feel with up to 35% less water - better pressure, a smaller bill, and a gentler spray on skin and hair, shower after shower.

HOW IT WORKS

Cleaner Shower Water Your Skin and Hair Can Feel

Two problems. Two different solutions.

Why Not Carbon?

Chlorine Neutralised the Moment Water Touches It

Chlorine removal is a race against contact time. Here's how long each technology needs - versus how long water is actually inside the filter.

WHY GERMANY & KOREA

Tested Where Filter ClaimsAre Taken Seriously

PICKI NIKI is engineered in Germany for European hard-water conditions. But it is developed, manufactured and tested in Korea.

There is a reason for that.

Korea is one of the world's most mature shower-filtration markets, where consumers pay close attention to the relationship between water, skin and hair.

It is also a market where product claims are regularly scrutinised and independently tested.

We evaluated manufacturing options across multiple countries. Korea was a more expensive choice. It was also the one we trusted most.

    Note: real shower conditions are typically higher pressure and warmer than this laboratory test. The Vitamin C gel cartridge is engineered as a self-regulating system: higher pressure releases more Vitamin C from the gel matrix, and higher temperature accelerates the chlorine-neutralisation reaction. Under typical shower conditions these dynamics are expected to keep real-use performance broadly comparable to the laboratory result.

    Pleasant smell

    Strong but soft jet Very good for our thick hair. My daughter likes to shower even more now. My son loves the water jet. I love the scent and the softer feel of the hair. My skin is no longer as tight as sun and feels much more comfortable. We are still using the original vitamin C filter for the 2nd week. We're very happy.

    Triple filter spa experience

    My water pressure wasn't reduced, this was good, as swapping showerheads seems to cause such issues. The design is very sleek and did not look out of place is the shower, if anything it upgraded it. The clear part on the shower handle is also a good design feature, as it allows you to view the debris and know when to change the sediment filter. Every home should have a PICKINIKI, no ifs , no buts, no regrets, no lies.

    Best shower head with water filter I’ve tried!

    After much research, I purchased this shower head with 2 integrated filters. I was expecting greatly reduced water pressure and modest reduction in hard water deposits on my shower and hair. The Picki Niki shower head with the handle filter and gel filter IMPROVED my water pressure with a wonderfully soft, but powerful stream of clean, softened water. My hair feels softer and I notice decreased hard water deposits on my shower pan. I LOVE IT and will absolutely repurchase!!
