Helllooo Doc!
Been on propecia almost exactly a year, not great results but things seemed to be stabilizing. About 3 months ago i added 2% nizoral shampoo to my regime and my hair has really thinned out since then. Have you ever heard of nizoral causing a shed or hairloss?

I haven’t heard of hair thinning or shedding with Nizoral (ketoconazole), but there’s really no way for me to tell what you are experiencing. If you think the shampoo is causing this new loss, stop using it and see if the problem subsides. You said the Propecia was stabilizing things, so hopefully that will continue. A baseline miniaturization study would help in a situation like this, because you’d know where you were with some objective numbers (the basis of good clinical science).
