You should consider using Propecia and Minoxidl together. By combining their use, you should be able to get better results than if you used them alone. Also, consider adding Lysine to your routine, which may make those drugs more effective.
As far as doing research, I think you can do a lot of legwork on the internet. This site has lots of good info. Read "The Best Procedure" and consider reading the articles in the Research Library. They are a little technical but very good. Other sites with good articles and forums are
www.TheBaldTruth.com and
www.HairlossHelp.com. These sites cover drug therapy (like Propecia) a little more thoroughly than this site, and you may find them useful. If you want to research different doctors, try looking at Pat's list of recommended doctors, and the recommended list at The Bald Truth. Then find these doctors' websites, and read up on them. Also, do searches on the docs you are interested in, in the forums of the websites I mentioned, to get comments and feedback from real patients who have had experience. There is a lot of reading, but this is the way to go. Right now, I would not suggest visiting any clinics. For one thing, most doctors don't have time to explain everything you need to know, in order to make an "informed decision". Since you are more interested in learning about the field for possible future procedures, it is premature to start meeting doctors. Learn about the field, and find out which doctors seem like the best choices. If you are still interested in pursuing a hair transplant in the future, then you can start trying to interview prospective surgeons. First though, learn as much as you can by using the internet.
And by the way, 2 or 3 months is not enough time to decide if a drug therapy is working for your hair. Most people say to give Propecia a year of consistent use, to decide if you want to continue. If you are able to halt your hairloss, it is worth staying on it, and this seems like a reasonable goal.
