I use the same soap on my hair as I do the skin, it would not make much sense to need 2 differant soaps...
Search the internet and see if anyone local is making a decent hand bar soap. I know christophers makes a BF&C soap, but I have never purchased one so I have no clue if it is any good, etc... Maybe it could be copied easier than trying to make the solid bar soaps.
"IF" the maker is not bragging that they use first grade olive oil, first grade essential oils, etc....then you know they are using cheap trash products chosen for soap making.
