Does finasteride reverse hair loss?

I ‘m 25 and have only taken Fin for a few weeks but this entire year I have had bad hair loss.  Started at one temple now my entire hairline is getting diffused thinning.  Will the finasteride reverse it it I stick to it?

Reversal of balding is not uncommon in men under 25. The younger you are, the more likely it will occur but that does hinge on your genetics. You won’t know until you try it.
