What happens if I drop my dose of finasteride from 1mg to half the dose?

I don’t know as everyone is different. Many people who drop the dose do just as well at half of the dose. With that said, I just saw a man who dropped the dose from 1mg to a half mg and saw hair loss from the drop. The studies that were done in the 1990s indicated that half the dose was 80% as effective on average as the full dose.
