When Niki moved to Germany, she started losing hair – more than ever before. She wanted a shower routine that worked with the local water. Berlin water has more dissolved minerals and chlorine than Seoul. She developed the PICKI NIKI filter shower head with Korean lab partners as part of her own filtered-shower routine. Today, many customers report softer-feeling hair, less mineral build-up, and a calmer-feeling scalp. Individual experiences vary.

Hard water can leave mineral residue on the scalp and hair, and chlorine can strip natural oils. PICKI NIKI reduces both at the source: your shower water.

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.
Real customers. Real water. Real change.
They tested it on their own water.
The Two Hidden Causes of Water-Related Hair Thinning
CAUSE 1: Hard Water Minerals
Calcium and magnesium build up on your hair and scalp. Every. Single. Shower. These deposits clog hair follicles, suffocate the roots, and make hair brittle and prone to breakage. Over time, the damage accumulates until your hair can’t grow back properly.
CAUSE 2: Chlorine & Chemicals
Chlorine strips your scalp of its natural protective oils, the oils that keep the hair shaft hydrated and reduce friction. Without them, the scalp dries out and hair becomes porous and fragile. Coloured or treated hair is especially vulnerable. The result is breakage and a stressed scalp barrier - separate from genetic hair-thinning causes, which a dermatologist should evaluate.
The damage is invisible – until it’s not
You won’t notice it at first. But every shower with unfiltered water adds another layer of mineral buildup. Follicles narrow. Hair thins. Growth slows.
By the time you see it in the mirror, weeks of damage have already accumulated. The earlier you switch, the more hair you keep.
Why PICKI NIKI is the Clear Choice
See the difference compared to a standard shower head

- ❌ Does not filter chlorine or heavy metals
- ❌ No skincare or hair benefits
- ❌ No aroma – plain sometimes smelly tap water
- ❌ Single-use plastic, no recyclable parts
- ❌ Weak, unfiltered stream

- ✅ Modular design, replaceable filters, less waste
- ✅ 200 micro-holes for powerful, filtered water pressure
How PICKI NIKI Addresses Two Daily Hair-Stress Factors
-
1
Removes what causes the damage:
The dual-filter system reduces chlorine and binds calcium and magnesium – the minerals that can leave residue on the scalp and hair.
-
2
Less mineral residue on the scalp:
Without chlorine and hard-water minerals on the scalp surface, residue can rinse off more easily. Many users describe their scalp as feeling calmer.
-
3
Nourishes with Vitamin C:
The vitamin C gel filter neutralises aggressive chemicals and delivers antioxidants directly to your scalp – promoting healthier, a more comfortable shower experience from the first wash.
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.
A Calmer-Feeling Scalp
Itchy scalp? Dandruff? Flaking? These are often signs of the same chlorine and mineral exposure that affects scalp comfort.
Filtered water reduces chlorine and mineral residue reaching the scalp - addressing two daily variables that can disrupt the scalp barrier.
Your skin benefits too: less dryness, less irritation, more hydration after every shower.
Safe for the Whole Family – Including Little Ones
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.

Independent open-label, single-arm 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. Sample size and design are appropriate for a tolerability/irritation screen, not a clinical efficacy trial.

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.
