Hello @Hans ! If you don’t mind me asking where do you buy your flowers of sulphur? I have been searching around and there is a lot out there but I am unsure if it needs to be NSF, or pharmaceutical grade or if the product that they use for gardening is the same product or how they would be different?For me it was link to starch intake as well as an fungal issue. It went away when I used flowers of sulphur.
Other oral anti-fungals can also work. I experienced no obvious die off, but the dandruff disappeared almost immediately.
