Agreed. My hairloss has gone into over drive since starting propecia 20 months ago. I don't have any symptoms typically linked with hyperandrogenicty, however.
May be in your case finasteride only impacted androgen sensitivity? That may explain hair loss even in absence of other symptoms. Perhaps your free testosterone level did go up but your body somehow avoided excess sebum production. Sort of what happens when we hit puberty. Everyone's testosterone level does go up but not all of us get oily skin/acne. Our bodies are so complex and vary so greatly that it is hard to predict with certainty what effects the med's dealing with something as delicate as endocrine system will have. Also, our understanding of male pattern baldness is far from complete so that doesn't help. Did you have hormone testing done prior to starting finasteride? That will give some answers.
