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 effectively softens the water and reduces the calcium and magnesium content – the culprits behind hard water.

Use against hard water: ascorbic acid binds with magnesium and calcium minerals, making them water-soluble. They can now be washed away, leaving no more residue on skin, hair or 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(C2H3O2) (calcium acetate, which is water-soluble).

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

One gram of ascorbic acid neutralizes 1 milligram per liter of chlorine per 100 gallons of water. 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 neutralize 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.

Our filter is not just a tool, but a treasure trove of skin-friendly ingredients.

Enriched with vitamin C, it neutralizes chlorine and makes your water pure and gentle. But that's not all – we have also added other natural elements known for their cleansing properties.

Every shower becomes a nourishing ritual that provides your skin and hair with essential nutrients, transforming your daily routine into a pampering spa experience.

Ascorbic acid (vitamin C): ascorbic acid, better known as vitamin C, is used here for its antioxidant properties. Vitamin C is a radical capture agent and has an antioxidant effect (so it acts as a reducing agent).

Combats hard water: ascorbic acid reacts with and dissolves magnesium and calcium minerals into water-soluble compounds. They can now be washed off and no longer leave residues on skin, hair or in the shower cubicle.

Glycerin: is used for its high moisture absorption, its occlusive properties (protects the skin from aggressions) and its emollient (for smooth skin and hair).

Collagen: is a very important protein molecule in the human body and a major component of the skin. It has the function of supporting the connective tissue of the skin like a scaffold, which makes the skin elastic and supple.

Hair thinning isn't just about genetics

- it's often triggered by what's flowing from your shower. PICKI NIKI's lab-tested shower head targets this hidden cause at the source.

By filtering out chlorine, rust, and hard minerals, it reduces residue on the scalp and hair shaft.

Many of our customers came to Picki Niki because hard water and chlorine were affecting how their hair felt.

What Customers Say

★★★★★

Highly recommended!

I live in a very hard water area of London and have noticed my hair and skin suffering from dryness and dullness, regardless of the quality of products I used. I filter my drinking water, so why not my shower water too? Picki Niki's showerhead is beautifully designed to feel compact and lightweight to hold. It enhances water pressure, and the lovely citrus fragrance adds a subtle touch that makes every shower feel like a spa experience!

Amanda T.London, UKVerified buyer
★★★★★

Filtered shower head with Vitamin C

I am extremely happy with the results of using this shower head, it completely exceeded my expectations. After only a couple of weeks of usage my skin is much softer and my hair is very shiny and soft. I bought this product because I live in London and the water is hard and my hair was dry and dull. I would 100% recommend. The delivery was also seamless.

Nicola C.London, UKVerified buyer
★★★★★

Great shower

I bought the shower head after a bit of research and it's been great. I'm based in the UK and it has improved the pressure from the electric shower. Additionally the filter provides a higher quality water, noticeable on hair and skin, and straight away you can tell the shower glass doors are much less streaky and easier to clean.

Gaizka B.United KingdomVerified buyer
★★★★★

My curls sprang back to life

I have struggled with my hair since arriving in England due to the high amount of lime in the water. I tried other showerheads before proceeding with PICKI NIKI. My hair is super soft now, and manageable again. Worth the money, for sure!

Clara H.England, UKVerified buyer
★★★★★

So great

Using this shower head has changed my life. My skin is no longer tight or itchy from limescale after my shower, my hair is shinier and the smell of Vitamin C is pure relaxation. I highly recommend it.

Christelle O.Verified buyer
★★★★★

Smooth hair and relaxing

I can tell the difference already in my hair. The frizz has decreased when I air dry it and the smell from the filter is amazing. Wanted to purchase for a while and glad I did.

Ina A.Verified buyer
★★★★★

Five stars

Living in Copenhagen and showering in very hard water, it gave me dry skin and hair ends, but it has helped a lot using the shower head. Also, no more discolouring on the shower curtain.

RikkeCopenhagen, DenmarkVerified buyer
★★★★★

Full endorsement

I absolutely love this product. Improved skin and hair, increased water pressure with decreased consumption, with aromatherapy as an added benefit. And super easy to install. I give this product my highest endorsement!

Anastasia L.Verified buyer
★★★★★

Perfect

Very easy to install myself, and it makes my bathroom smell so good. I love how the Vitamin C makes my skin so soft. I feel like this also makes a difference when I wash my face in the shower. So glad I decided to buy this.

Certificates for PICKI NIKI

Four Steps. One Shower.

STEP 1: Sediment Filtration

A dedicated 5μm pre-filter catches rust, pipe debris, and grit from old plumbing - the first thing most shower filters skip.

STEP 2: Less Hard-Water Residue

Hard-water minerals leave that tight, residue-like feeling after showering. The Vitamin C stage helps reduce visible mineral build-up on skin and hair.

STEP 3: Chlorine Neutralisation

The Vitamin C reaction reduces free chlorine to non-detectable (KEWI lab, 2020). That means a shower that won't strip your skin's natural oils or roughen your hair.

STEP 4: Stronger Spray, Less Water

A 200-hole precision plate gives you stronger feel with up to 35% less water. Better pressure, smaller bill, gentler on skin and hair.

WHY NOT CARBON

Carbon Was Built For Kitchen Taps. We Changed The Chemistry.

Most shower filters are repurposed drinking-water tech10 - activated carbon, mineral beads, KDF media - all designed for cold tap water with minutes of contact time. In a real shower, water passes through the cartridge in ~0.1 seconds at 40 °C+.3 Catalytic chlorine reduction by activated carbon needs 25-40 seconds of empty-bed contact time4 - 25× longer than a shower allows. PICKI NIKI uses Vitamin C (ascorbic acid), where the chlorine redox reaction runs faster with heat, not slower. Built for shower physics from scratch.
PICKI NIKI shower filter - built for real showers
  • Sub-second reactionVitamin C neutralises chlorine via direct redox - no contact-time bottleneck like adsorption media. ~0.1 s residence time at 7.5 L/min shower flow.2,3
  • Temperature-positiveReaction speed increases with heat (Arrhenius). Activated carbon by contrast needs 25-40 seconds of empty-bed contact time for chlorine reduction (WQA), while a shower gives under 1 second.
  • Hard-water activeReacts with calcium and magnesium minerals - softens water as it filters, not as a separate stage.
Mechanism over marketing

A Filter Built For a Real Shower. Not a Kitchen Tap.

Two filters working together inside one shower head: a melt-blown PP sediment pre-filter in the handle (sealed full-flow housing, 100% pass-through), and a Vitamin C gel cartridge in the head. Then look at how the rest of the category was built - for cold, slow drinking water.

What's Actually Inside.

Filter 1 · In the handle

Melt-blown PP sediment filter

Catches rust, sand and pipe debris before water reaches your skin. Melt-blown PP pre-filter in sealed full-flow housing - 100% of water passes through, no bypass possible. Lasts approximately 1-3 months, replace as a 3-pack.

Melt-blown PP sediment filter
Filter 2 · In the head

Vitamin C gel cartridge

Ascorbic acid reacts with chlorine on direct contact - a fast redox reaction that accelerates at warm shower temperatures, and reacts with calcium and magnesium so hard water stops drying out skin and hair. Lasts ~2-4 weeks with a visible end-of-life as the gel is consumed.

    TECHNICAL DETAILS

    Specifications

    PICKI NIKI is a Vitamin C shower filter, designed in Germany, made in Korea, engineered for hot water, high flow and the actual conditions of a real shower. Two filters in one head: a melt-blown PP sediment pre-filter in the handle (sealed full-flow housing, 100% pass-through) catches rust and pipe debris, then the Vitamin C gel filter in the head neutralises chlorine on contact and reacts with calcium and magnesium so hard water is gentler on skin and hair. Independently tested at three Korean labs: P&K Skin Clinical Research Centre (clinical irritation, n=30, non-irritant), KEWI (chlorine + drinking-water) and KTR (pH performance). Universal fit on any standard shower hose, no plumber required. 1,000+ verified five-star reviews across the UK, Germany and the EU.

      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.

      Really happy with this shower head so far

      I’ve been using this shower head for a couple of months now. It was super easy to install, and the replacement process for the filters was very straightforward. I love the scent from the vitamin C filter every time I turn on the shower. And the water pressure is great as well.

      So easy to use

      Having given up on a UK competitor whose quality control with regard to filtered showerheads seemed to be non-existent, the PickiNiki is a breath of fresh air. The quality of the showerhead is better and feels more substantial. Removing and replacing filters is so easy and quick, no scrambling around with a useless tool as I was doing before.

      I have tried them all

      I have tried so many shower filters and this is the only one that has genuinely made a difference! I travel with it from country to country to overcome the varying hard water I come across.
