How to increase gains..?

I've been on topical minor for 2 years only for my beard. (1rst pic was taken in 2023). Then I tried 5 drops per day during 2 months this summer. And Switch at September 2024 for 5mg minox on tablets, then 10mg this month. I don't see that much results. Any advice ? The second picture is from today, and I'm trimmed btw. Maybe I'll try supplement like zinc and boron.
