I live in a hard water area can I use sulphate free shampoo with chelating shampoo once in a while?

1 Answer

I am sure it is fine if you only use it once a month or every few weeks. however, there are sulfate-free chelating shampoos such as  Pureology Purify Shampoo, if that is something you are worried about. or you could get a hard water filter to put on your shower head.
