Does finasteride eventually stop working over time to either regrow or maintain hair for everyone that takes it as their genes for balding take over?
Finasteride maintains benefits; however, your hair’s ability to stop its eventual pattern may not be stopped by finasteride, just slowed down. I have seen men on finasteride for 15-20 yrs stop it, and they lost significant amounts of hair as a result suggesting even that far out (20 years) doesn’t stop finasteride’s effectiveness
