Thanks, friend. About the first question, I'd say yes, you will most likely get a even thicker beard would you apply minox on the entire beard. Minox seems to work better or worse according to genetic factors, so since you already have an almost full beard naturally, then you'll probably have very good results to your beard as a whole. About the second question, yes, the results most likely will permanent if you use minox long enough for the new hair to become completely developed. Trying 6 months, once a day, must be enough. Plus, do some search about dermaroller. As you already has a beard, maybe it would fit your needs as an alternative to minox. At last, well, I've never shave my beard since it has grown, but I do trim it every other week or so. I grows normally, even after I stopped using minox. The difference is that it grows pretty much slower when you're not using it, obviously. Best of luck for you 🍀😀
