Can using a water softener cause itchy skin?
Yes, one can be allergic to anything. If nothing else has changed. Do a trial, stop using it and see if you get better (may take a little while). Then if you use it again and itch again, you'll know for sure.





This is called a SPOT trial Single Person One Thing.





See how you go.
