I live in a hard water area and hate it. Mainly because it's awful on my skin and hair. Eventually I'd like to install a proper water softener machine in my house but I'll only do it once I re-do my kitchen. So the alternative is to get one of those shower heads with a water softener in it.
My question is if they are any good or if it's a massive gimmick? Any recs for one that works and doesn't cost a small fortune?
