zix people, I have read about the zink inhibiting 5 alpha reductase. But I think if you are going to go that route, you better add B6 and Azaleic acid to the mix. But since the study did not mention type 1 or 2, you have no way of knowing if it even inhibits type 2, which is in hair follicles. So you better use an androgen receptor blocker to be safe. I recommend Nizoral, and either lavender or spironolactone. Both are growth stimulants too. I still would not feel safe though.
