"After washing my hair just once, it felt smoother, silkier and shinier."
– Louise Whitbread
During testing, Louise Whitbread reported that her hair felt smoother, silkier and shinier after a single wash, and described a clear improvement in dryness and frizz over two weeks. She linked the results to the vitamin-C gel filter – which also contains glycerin – reducing the residual chlorine left on hair washed in hard water. Read the current guide at independent.co.uk.

"Often when I shoot beauty and hair campaigns, I do the final rinse with bottled water. Since using PICKI NIKI, not anymore."
Amy Hunt, AIT
Associate of the Institute of Trichologists
"Consumers are increasingly investing in premium hair and skincare products yet often overlook the quality of the water used every day."
Stefan Scholz
Hairdresser, Berlin
"As a hairdresser, I look for long-term results rather than instant impressions. One of my long-term clients noticed softer-feeling hair and no visible green tint after using PICKI NIKI. I would happily recommend it."
These statements reflect the personal opinions of the experts.
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!
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.
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.
