Doctor House mentioned William The Bloody on HLH.
Apparently his hair got worse after a few years on finasteride; he dropped it, and slowly his hair got better. BUT, he is also using Rogaine twice a day, spironolactone Cream once a day, and Ell Cranell Alpha once a day to fight his male pattern baldness--basically an all-topical approach.
Irish, as someone said, NOBODY knows if your hair will get better. The only way you can find out is to stop it and see. In the meantime I would suggest using a potent topical regimen like the one listed above.
