I stopped Rogaine and lost my hair (photo)

I used Rogaine for 1 year. I thought it wasn’t helping and my shed picked back up 8 months in. I quit Rogaine this last December and about the last month have had huge shed. Sometimes 300-400 hairs. I am45-year-oldd female with FPHL. Should I go back on Rogaine? Will that decrease shed and can I take Fin as I have had a hysterectomy? My temples and sides are the worst, losing density.

Going back on Rogaine may return the hair and it may not. A Hair transplant is a reasonable option that will absolutely put the hair back where it was lost.
