Dry skin, brittle hair? The problem is not you - it might be your water.

If you shower in London or the South East, your water is among the hardest in Europe - several times the dissolved minerals of a soft-water city. You’ve watched it fur up your kettle and cloud the shower glass. The same hard water, plus the chlorine UK water supplies are required to carry, runs over your skin and hair every single day.

  • Helps reduce the hard-water & chlorine stressors behind dry-feeling skin and hair
  • Neutralises chlorine, filters rust & sediment, and reduces limescale residue
  • Spa-like pressure with a 60-day money-back guarantee

The problem often isn’t your routine - it’s a hidden stressor: your water.

These are the 12 most common problems hard water and chlorine cause - and how PICKI NIKI solves each one.

The 12 most common water problems - solved

Video poster
Skin

1. Skin That Feels Tight the Moment You Towel Off

You moisturise the second you step out - and by lunchtime skin feels tight and papery again.

It isn’t your routine. The limescale that furs up your kettle is in the same water running over your face every day. Hard water and chlorine strip the oils your barrier needs, particularly on sensitive skin¹ - so it leaks moisture instead of holding it. No cream fixes water.

PICKI NIKI takes the chlorine and mineral stress out before the water touches you - so your shower stops working against your skin.

Hair

2. Hair That’s Gone Dull, Dry and Hard to Manage

Freshly washed - and it still won’t shine or sit right.

The same film that clouds your shower glass builds up on every strand. Chlorine roughens the surface, hard-water minerals weigh it down - so hair looks flat and feels heavy no matter which mask you try.

PICKI NIKI’s dual filtration lifts that daily load, so hair feels softer, lighter and easier to manage from the very first wash.

Hair

3. Hair That Looks Flatter and Thinner Than It Used To

More scalp in the mirror than there used to be - more strands in the plughole.

Thinning has many causes, and the genetic or medical ones belong with a professional. But one daily factor you can control is your water: chlorine and hard-water minerals stress the scalp and coat every strand, weighing hair down so it looks limp and less full over time.

PICKI NIKI filters the chlorine and reduces the residue reaching your scalp and hair, so it looks fuller and moves lighter. Individual experiences vary.

4. Skin That Reacts to Everything - Even Water

The gentlest products, and skin still flares, tingles or turns blotchy.

If the water itself is harsh, no cleanser can make up for it. Chlorine strips the oils that keep skin calm and leaves it quicker to react with daily exposure - so the problem starts before your routine even does.

PICKI NIKI is dermatologically tested non-irritant (P&K Skin Clinical Research Centre, n=30)² - a gentler shower for skin that’s had enough.

Family

5. The Whole Family Showers in It - Even the Little Ones

Your kids’ skin is more delicate than yours - and it meets the same water every day.

The chlorine and hard water that stress your skin reach theirs too, on every bath and shower. One filter on the family shower changes the water for everyone in the house.

PICKI NIKI is dermatologically tested non-irritant (P&K, n=30)² - gentle enough for the whole family.

Hair

6. Salon Colour That Fades Before Your Next Appointment

You didn’t pay for salon colour to watch it wash down the drain.

Chlorine and hard-water minerals dull and strip colour-treated hair, so it turns brassy and flat weeks before your next appointment. The water undoes the work every single day.

PICKI NIKI filters the chlorine and reduces mineral residue, helping your colour stay truer and glossier for longer.

Scalp

7. A Scalp That Itches and Flakes by Evening

That tight, itchy scalp - and flakes on your shoulders by the end of the day.

Your scalp is skin too, and it meets the water first. Chlorine strips its natural oils and shifts its pH, and with a daily-shower habit that stress adds up fast.

PICKI NIKI filters the chlorine that dries your scalp out, so it feels calmer and more balanced.

Skin

8. Serums That Just Sit There

Expensive serums, and your skin seems to drink in nothing.

Hard-water residue leaves a fine film on skin that products have to push through - so even a good routine can feel like it’s working at half strength.

PICKI NIKI reduces that residue, so the skincare you already own has a clean surface to work on.

Shower

9. A Shower That Smells Like a Spa, Not a Pool

That faint swimming-pool note the moment the hot water hits.

UK supplies are required to carry a chlorine residual, and warm water lifts it into the air. Filter it out and that harsh edge is gone - and the Vitamin C gel comes in gentle scents (Tea Tree, Baby Powder or Unscented) that leave the water soft and calm.

PICKI NIKI turns your shower into the ten minutes you actually look forward to.

Pressure

10. Filters That Trickle. Ours Doesn’t.

Most filters choke your pressure down to a sad trickle.

Not this one. 200 precision micro-holes hold a strong, even, spa-like stream - while using up to 35% less water.

PICKI NIKI gives you pressure and purity, not a trade-off.

Value

11. The Pricey Products That Never Quite Deliver

Shelves of premium products - and skin and hair that still won’t behave.

If the water you rinse with is the problem, every product is fighting uphill. Fix the base first, and the rest of your routine finally gets a fair chance.

Clean water is step zero - the one upgrade that makes everything after it work better.

12. No Tools, No Plumber, No Excuses

Worried it means tools, tape and a plumber?

It doesn’t. PICKI NIKI twists onto any standard shower hose in about 20 seconds - the easiest upgrade in your bathroom.

The same you – without the water stress

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.

Not all shower filters are equal

Why the PICKI NIKI filter is built differently

A Vitamin C gel cartridge that reacts with chlorine on contact, plus a melt-blown sediment pre-filter. Here's how that compares with the media most shower filters use.

"It actually works."

“I used to spend a fortune on skincare and hair masks - but nothing worked. I never imagined the problem was my shower water.

    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.
