Swap from topical to oral finasteride

I apply at a .25g dose so the bottle lasts about 3.5 months so the prices doesn’t bother me, and I’m not bothered by applying topicals. Just wondering if there’s any point as I see loads of people be like blah blah it goes systemic just the same no point etc etc

Yes, you should be able to switch from the topical form of finasteride to the oral form without consequences.
