I miss that water softener every single day. ANY PRODUCT WORKS on my hair when it isn't battling a calcium coating. It was shiner, softer, held moisture better, the color appears deeper and darker, it stayed soft all day even w/o product. I actually had to be careful not to overmoisture.
Right now, in the new house, I only use bottled water on my hair (I buy the 5 gallon drums) and siphon water out until it's light enough to pick up.
I got fed up and ordered an in shower softener. People frequently mistake water filters and water softeners. Filters don't soften and softeners don't filter. Meaning a filter won't take out hard water minerals and a softener won't take out chlorine. They are entirely different. A softener has to be "recharged," meaning you have to rinse the minerals it's collected from the medium. I think it's every 20 uses for this model. It does it automatically (on a timer) when it's the whole house softner. Filters, by contrast, only need to be replaced once/year. If the instructions on your device doesn't say "rinse every X number of uses with salt water" then you don't have a water softener. You have a water filter and you still have hard water.
Here's the only "in shower" water filter I've ever heard of. An LCHF'er started a thread about it but despite my best efforts I haven't been able to find it. It filters
and softens and it was only $180!
The whole house water softener we had on the old house was $1300 (i think). It kept hard water minerals off the facets and sinks, from fading clothes in the washes, the dishes from drying with white spots, and baths were just heavenly. Unfortunately, we have other priorities right now and
another whole house will have to wait until spring.
The WaterStick should be delivered today. It's supposed to be easy to setup. We'll see.
I'll post a review as soon as it comes in.
ETA: I'm not knocking filters. Chlorine will do nasty things to hair and skin. I have a filter on my shower head and I can tell the difference. I just want to make it clear, if you have hard water it will still be hard after you've installed a filter.
