Hard, mineral-rich water can be a burden on skin and hair. The PICKI NIKI filtered shower head works wonders by using advanced filter technology.
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 (>99%).
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.

Two filters working together inside one shower head: a cotton-blend sediment pre-filter in the handle, 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.

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.

By filtering out chlorine, rust, and hard minerals, it helps restore scalp balance and strengthen strands - right from the root.
32.9% of our customers came to PICKI NIKI for hair-thinning concerns.
The sediment filter in the handle traps rust, dirt, and large particles from the water. This ensures a clean start to your shower.
The vitamin C gel filter reacts with and dissolves calcium/magnesium minerals so they rinse off instead of building up on your skin and hair. No more dryness & irritation, or dull hair.
The vitamin C filter reduces chlorine to non-detectable levels (>99%). This reduces dryness and irritation caused by residual chlorine from water treatment.
200 precision micro-holes create a silky soft yet powerful water flow. This ensures a thorough and gentle cleanse without harsh pressure.

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 cotton-blend sediment pre-filter in the handle 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.

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.
Looks good , water pressure seems better too.
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.
It solves Hard water, Skin Irritation and shower head pressure issues and cherry on top is modular design. Thank you for existing.
I cannot believe the difference in the condition of my hair using the Picki Niki shower head! My hair is very fine and tangles easily when wet and no matter what shampoo or conditioner I used nothing made a difference. Why isn’t everyone taking about using a shower head filter! It’s the best purchase for improving hair condition. A beautiful contemporary quality design, easy to replace your existing shower head and it smells divine. There is no loss of water pressure either and my hair is smooth and easy to manage after every wash! Well worth the investment
