Your shampoo might not be the problem. Your water might be.
New apartment. New water. New problem.
It started with a move. Same routine, and suddenly heavy hair shedding and dry, itchy skin in the household. Switching shampoos and moisturisers changed nothing.
Matt Polzin started digging into the one thing that had changed: the water. Australian city water is treated with chlorine and chloramines, and the filtered showerheads on offer were bulky, weak or a pain to install.
So Matt designed one that wasn't. After the switch, the symptoms that started it all settled down, and in July 2025 Flowy launched to bring the same fix to other Australian households.
Chlorine keeps tap water safe to drink. It isn't so kind to skin and hair.
Australian city water is treated with chlorine and chloramines. In the shower, that can leave skin feeling dry and hair frizzy, and no shampoo or moisturiser fixes the water itself.
01
Install in two minutes
Fixed and handheld showerheads screw onto standard fittings by hand, with no tools or plumber.
02
Filter every shower
A three-stage cartridge of KDF-55, calcium sulfite and catalytic carbon cuts chlorine and heavy metals as the water flows.
03
Swap every three months
Fresh filters can arrive on subscription, and every showerhead comes with a 60-day money-back trial.

In mid-2024, a year before Flowy launched, we advised founder Matt Polzin as the business took shape.
“Yianni was great and took the time to understand the requirements of the project and gave great insights. Would highly recommend for anyone looking for an advisor in a startup.”
