Rogaine and finasteride, How long do they work?

I’m just curious if anyone knows how long the regrowth will last on finasteride before it stops and if there’s any possibility of regrowth beyond maybe 10-15 cm up top for people in my position. thanks all.

Both Rogaine (minoxidil) and Finasteride have peak actions in about 2 years. They usually maintain the benefits provided that you continue to take the drug, otherwise, all of the benefits are lost in a few months.
