Can You Have Hair Loss After Stopping Propecia For Three Weeks?

I have a question for you.

I’m taking finasteride 1mg now for two years and my hair improved a lot.
Now with exams and very busy schedule I forgot to make an appointment with my docor. I now have one in three weeks. But now i’m afraid i’ll lose my hair again because i’m out of finasteride for three weeks.

Is it possible i can lose a lot of hair in three weeks?

It is possible that you can lose hair after stopping Propecia for three weeks. It generally takes longer for “catch up” hair loss to occur. Catch up hair loss is basically the loss of your native hair that benefited from the use of Propecia.
