Jeff,
Switching to dutasteride after 6 months on finasteride is childish. Either you should have been using dutasteride from the start or given finasteride 12 months to assess results. At six months I had zero results with finasteride and at 12 months my hair clearly looked better then when I started. I don't get you man, you are so frantic. Your hair is not even that bad and is certainly not at a point where you need to throw dutasteride at it. I can tell that you really only need some added density to have your hair look 100% normal as I have the same sort of loss. If finasteride cannot give you this slight increase in hair density then neither will dutasteride.
I feel for you and can understand your anxiety and depression. However, I wanted to point out to people who are researching whether they should start a regime, that Jeff's decision to switch to dutasteride after 6 months on finasteride is not wise and an example of what not to do.
