You cannot feel it.
The mineral in hard water is dissolved. It has no taste, no smell, and no feel in the water itself. You only feel what it does to your hair, months later, by which point you are blaming the shampoo.

Why check
Three reasons to look before you buy another bottle.
The odds are not in your favour.
72 of the UK's 124 postcode areas are supplied with hard or very hard water. If you live in England, you are more likely in one than not. The report replaces the guess with your own number.
Everything else goes on after the water.
Water first. Then shampoo, conditioner, mask, oil. If the water is the cause, every product you own is arriving after the damage. Checking is the first step that is not another bottle.
Twenty seconds now, or another year of treating the wrong thing.

What you will see
Twenty seconds from now you will know four things.
- 1
How hard your water actually is.
The figure in milligrams per litre, translated into plain English, and how it compares with the softest water in Britain.
- 2
How much chlorine is in it, and which disinfectant your supplier uses.
Some suppliers use one that ordinary carbon filters barely touch. It changes what you should buy, if you buy anything.
- 3
What that has been doing to your hair.
Wash by wash, for as long as you have lived at that postcode, in numbers you can picture.
- 4
A straight verdict.
Whether a shower filter is worth it for your postcode. If your water is soft, we say so, and you can walk away.
Where the numbers come from
Not our opinion. Your water company's own figures.
Every claim in your report can be traced to a public source. This is the whole basis of it.
22 suppliers. 124 postcode areas.
Hardness, chlorine level and disinfectant type for every main UK water company, as they report it to the Drinking Water Inspectorate, mapped to the postcode areas each one supplies. Published under the Open Government Licence.
14,439 reviews. 12 brands.
Before we sold a single filter we read what people wrote after they changed their shower water, across twelve competing brands. What happens to hair, in what order, and how long it takes. That is where the "what to expect" in your report comes from.
Written up, with sources.
How hard water builds up on hair, why chlorine strips it, and why softening is not possible at shower scale. All on our science pages, cited, before you give us anything. Is UK water bad for hair · Hardness by region · Hard water and breakage

Customer proof
“I changed nothing else, just fitted the filter, and around three weeks later my hair finally felt normal again.”Oliver S. · Very hard water
The people who fixed their water first are the ones whose products started working again. The report tells you whether you are one of them.
Before you type
Why we ask for your email, and the three things people ask first.
The full report is four readings and a verdict, written for your postcode. We email it so you can keep it, forward it to whoever shares your shower, and check it against your own shower screen. That is the only reason.
"Is it really free?"
Yes. No card, no purchase, no trial. The report is the whole thing. If it makes you want a filter, that is a separate decision you make on the next page, or never.
"What if my water is soft?"
Then the report says so, in the first line, and tells you mineral is not your problem. About one in five UK postcode areas are soft. We would rather tell you than sell you something.
"Will you sell my email?"
No. You get your report, then the occasional email from us about water and hair. One tap stops them. Nobody else ever sees your address.
Why now
Tomorrow's wash adds another layer.
Whatever is in your water is on your hair again tomorrow morning, and the morning after that. The check takes twenty seconds and costs nothing. The not checking is what has been expensive.
