Read the last thing I wrote, again. It actually says on the package that keto could make you shed, that's for a reason, it's quite potent. That's why it's in the big 3.

"Conclusion
In men with hair loss, using 2% Nizoral shampoo 2-4 per week significantly improved measures of vertex hairs in anagen phase and hair diameter during the course of a 21-month study. At 15 months, the increase in the hair growth score was close to 50%. A slight decrease in hair growth scores was seen in those using normal shampoo. "
"Conclusion
Ketoconazole, the active ingredient in Nizoral (and some other) shampoos, was more effective than minoxidil in increasing hair count in men with vertex hair loss after 6 months. The increase in hair shaft diameter was the same with both ketoconazole and minoxidil. The two products appear to work through different mechanisms, as ketoconazole decreased sebum production while minoxidil increased it. "
Last one: 2% keto compared to 2%minoxidil. 1% keto is probably almost as good as 2% keto.
It's your choice, you could quit if you want.
