You’ve tried the clarifying one. The “sensitive scalp” one. The expensive one your friend swore by. Some helped for a day. None of them fixed the tight, itchy feeling after you shower, the flakes on your dark shirts, or the itch that comes back at night.
Here’s what almost nobody stops to think about: every one of those shampoos was rinsed off with the same water.
60-day refund. No need to send it back.
Reason 01
Your shampoo isn't the only thing touching your scalp
You picked your shampoo. You picked your conditioner. You never picked your water, and it’s the one thing on your head every single day.
So when shampoo after shampoo lets you down, it might not be the shampoo. It might be what you’re rinsing it off with.
This isn’t a treatment for anything. If your scalp is red, painful or getting worse, see a dermatologist. This is about the everyday dry, tight feeling, and an easy way to rule your water in or out.
Reason 02
Did it start after you moved? You're not imagining it
New city, new apartment, new campus. A few weeks later your scalp feels different, and you can’t work out why.
You’re not the only one. People post about it all the time:
“Why is my hair/scalp (I guess feels itchy and dry) forming into flakes after I came to Irvine, California?”
“Same problem here. Didnt have any issues in Other states or India.”

One person got so fed up they washed their hair with bottled spring water, just to test it. That’s how far people go to answer one question: is it the water?
Here’s what changed. Most US cities add chlorine or chloramine to tap water to make it safe to drink, and which one they use, and how much, changes from city to city. It’s a public-health win for drinking water. It just wasn’t designed with your scalp in mind.
Dermatologists also suggest warm, not hot, showers. Easy to try tonight.
Reason 03
The fix goes behind the showerhead you already own
No new showerhead. No plumber. No asking your landlord. A whole-house water softener costs far more, needs a plumber, and needs your landlord’s yes.
This doesn’t.
Calore Relief is a small filter that screws in between your shower arm and your showerhead, by hand. When you move out, it comes with you.
Inside, the water passes through four layers before it reaches you:
- KDF reduces chlorine
- Coconut-shell carbon reduces chlorine
- Calcium sulfite keeps reducing chlorine in hot water
- Vitamin C neutralizes chlorine
Then it comes out of your own showerhead, the one you already like.
It’s not a water softener, and we’ll never claim it is. No shower filter removes the calcium and magnesium in hard water. What it does reduce is the chlorine your city adds. The stream may also feel a little softer, because the water now passes through a cartridge.
Reason 04
Why not just buy a $25 filter, or a $150 showerhead?
Honest answer: plenty of $25 filters look a lot like ours. Here’s what you get for the difference:
- Straight answers: every layer is listed above, and we make no claims we can’t back up. We’ll never tell you it softens your water
- A brand that actually answers: email us and you’ll hear back within 48 hours
- A guarantee where you don’t even send it back (see below)
The three things people hate about shower filters
- Weak pressure. The water passes through a cartridge, so the stream may feel a little softer. If you don’t like it, see reason 5.
- Leaks. Thread tape comes in the box to help it seal by hand.
- Subscriptions. There aren’t any. A new cartridge is $24.95, when you want one.
And the $150 filtered showerheads? They make you throw out the head you chose.
Reason 05
60-day money-back guarantee
Try it for 60 days. If it's not for you, keep it, and get your money back
What you actually want is simple: to step out of the shower and not think about your scalp for the rest of the day.
Maybe it’s the weather. Maybe it’s your shampoo. Maybe it’s the water. You’ve been guessing for months. The simplest way to find out: shower with filtered water for a few weeks, and notice how your scalp feels when you step out.
If it doesn’t make a difference for you, email us within 60 days of delivery. We’ll refund you in full. You don’t have to send it back.
No risk. No trip to the post office. Just an answer.
Every shower until then is the same water.
Orders ship from a US warehouse with tracking. US delivery usually takes 5–10 days. Want a spare cartridge ready for later? You can add one on the next page.
60 days · refund without sending it back
Getting one for someone else too?
Both covered by the same 60-day guarantee.
