Restarting finasteride

I experienced further thinning one year on fin and stopped it. Im 32 years old NW1.5, should I give Fin a second chance risking 1 more year?

It’s not a good idea, assuming no side effects from finasteride, to stop it.  That allows you to lose more hair. I tell everyone that finasteride is always working at the least to slow down the hair loss and at the best it may reverse it (common in men under 25).  I would go back on finasteride and stick to it.  You should be managed by a good hair doctor.
