Yeah, I think most here do not experience sides. Although I've seen two people here in this thread who said they had side effects although 10x less than when they were on fina if I recall correctly.
But of course, I don't doubt that some people who are very sensitive could experience sides effects since Zinc and B6 working in a symbiotic way cause AA effects, hence zix being effective against hairloss.
Imo, zix should be one of the first lines of defence against hairloss. Cheap, relatively safe and seems to work. Especially for young guys and people who's hairloss is not aggressive.
When are you planning to start yourself btw? The more individuals try, the more the community learns
