hello there
welcome to the forum! 🙂
no the taoist soap does not have any drugs or such chemicals in it. Also on a note, since you mentioned minoxidil, it is not actually that effective in hair growth, because the results go after some time, and then you are left with needing to permanently using it for life! which is simply stupid…
The science behind how it works is the synergy of the ingredients, this is what pharmaceutical companies will never understand, or at least not show they understand, as you cannot beat the synergy of nature itself, designed to manage and be in the environment it is born in – sorry getting carried away here, but hope this helps.
