Long term use of minoxidil wanting to add finasteride

So I have been using minoxidil for over a year, by the 6 month period I gained alott of hair back and my corners and hairline was really good . Then around the 9-10 month window I started to notice shedding which by the 12-14 month window it was becoming worse then it was in the beginning. Now I’m at the 16 month mark and I have really short hairs on the part that I usually apply minoxidil to, but my hairline and corners is just really thin and as you move back it gets significantly thicker but they are still much shorter hairs then the ones on the rest of my head . Now I’m planning on hopping on finasteride and just wondering if in doing so I can expect to go back to how it was 6 months ago or is that not likely. Also how’s your experience go with started minoxidil long/short term before adding finasteride
