Been on rogaine for 3 months, how do I know it works?

[The Prestige]

Been applying it once a day to my crown and center of head. Can't really see a difference in these areas, but oddly I have a ton of little thin hairs sprouting all over my hairline(I have a NW2 maybe, hairline isn't a big issue for me). Is this a good sign? Will these turn into normal hairs? How much longer should I give rogaine?


Can't apply it more than once or I get sides and no I can't take propecia, I already have super low T and suffer from the dreadful sides people get on propecia (need to go on TRT soon).
