It’s not your shampoo. It’s not your genes. It’s calcium, chlorine, and rust in your water – silently damaging your hair every time you shower. PICKI NIKI removes the hidden cause so your hair can finally recover.
As seen in
After moving to Berlin, Niki noticed how different the shower water felt. Berlin has more dissolved minerals than Seoul. So she built her shower routine around filtered water. She developed the PICKI NIKI filter shower head with Korean lab partners. Many customers report softer-feeling hair after switching to filtered water. Individual experiences vary.
TESTED AT THREE INDEPENDENT KOREAN LABS
Many customers report softer-feeling hair and easier styling after switching. Individual experiences vary.
Many users describe their scalp as feeling calmer after switching to filtered shower water. Individual experiences vary.

Old pipes carry tiny rust particles and sediment that settle on your hair and scalp. The result: dull, heavy hair that’s lost its natural lightness. These particles also clog pores, causing scalp irritation and breakouts.
Calcium and magnesium build up on your hair. Every. Single. Shower. This invisible coating makes hair heavy, dry, and impossible to style. Your expensive products can’t penetrate through mineral layers – so they simply stop working.
Chlorine is a powerful oxidiser that attacks hair proteins, especially keratin. It strips natural oils, makes hair porous and brittle, and fades colour-treated hair. Over time, chlorine exposure leads to split ends, breakage, and accelerated hair shedding.
Low water pressure means shampoo and conditioner aren’t rinsed out properly. Residue builds up, weighing hair down and preventing products from working. The result: hair that never feels truly clean, no matter how long you shower.
Itchy scalp? Dandruff? Eczema flare-ups? These are often signs of chlorine and hard water damage – not just dry skin.
Filtered water removes the irritants that clog pores, cause breakouts, and disrupt your skin’s natural barrier. Your scalp calms down, flaking reduces, and your skin feels softer and more hydrated after every shower.
Less reliance on heavy creams. More confidence in your skin.
See the difference compared to a standard shower head
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 (KEWI lab test). Less chlorine on contact means less residue on skin and hair.
200 precision micro-holes create a silky soft yet powerful water flow. This ensures a thorough and gentle cleanse without harsh pressure.
We filter our drinking water. Why not our shower water?
Children and babies have more sensitive skin that’s especially vulnerable to chlorine and hard water minerals. The PICKI NIKI filter uses only skin-friendly, EWG Green Grade ingredients – dermatologically tested non-irritant (P&K Skin Clinical Research Centre, n=30).
One shower head protects everyone in your household. Nearly 1 in 5 of our customers choose PICKI NIKI specifically for filtered water for their family.
The vitamin C filter adds a subtle, refreshing scent – turning every shower into a mini spa moment.
No plumber, no tools. Simply screw it on and enjoy filtered water immediately.
Comes with a travel pouch so your hair stays protected – even on holiday.
Sediment filter + vitamin C gel work together to remove chlorine, soften water, and neutralise minerals.
250 lemons worth of vitamin C per filter – nourishing your scalp and neutralising chlorine on contact.
200 precision micro-holes create a silky stream that rinses thoroughly without harsh pressure.
You’ve spent hundreds on shampoos, treatments, and salon visits. None of them fixed the root cause.
PICKI NIKI costs less than your morning coffee – and it tackles the one thing no product can: your water quality. The starter set includes everything you need. Replacement filters start at £15/month.

Independent 24-hour patch test on Vitamin C filter material. n=30 (28F/2M, mean age 47.2y). Skin Irritation Index 0.03 (range 0.00-0.25 = non-irritant). Zero adverse events.

Korea Environment and Water Works Institute (KEWI). Residual Chlorine Removal Test. Seoul, Korea. 2020.
100 L synthetic water at 0.19 mg/L free residual chlorine, passed through Vitamin Filter. Outlet: not detected. Flow 2.52 L/min. T = 21-23 degrees C.
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.
