The "big 3" of hairloss treatments seem to be:
1. propecia (finasteride) or dutasteride (a stronger version of the same drug)
2. rogaine (minoxidil 5%)
3. nizoral 2% (a shampoo)
I have been using all 3 since 2004 and I seem to have stopped my hairloss cold, although I haven't really regrown much of what was lost. Personally I have found the finasteride to be the most effective for me. I will probably discontinue use of 2 & 3 soon if I don't start seeing some noticeable progress by 2008. I have recently switched to dutasteride from finasteride to see if that will stimulate new growth.
You can buy these drugs from online pharms for much cheaper than what a retail pharmacy will charge. The reputability of the online pharmacy is always a question, but I have bought from the same 2 places for the past 3 years and have not noticed any additional hairloss since I started taking the drug, so either my genetics were programmed to not lose any hair during the same timeframe as when I have been taking the drug, or the drug is legit.
I take a pic of the top of my head once a month right after I get a haircut. I then date the pic and use these as a reference to track progress. Hair loss/regrowth is a very long process and you will drive yourself insane if you try to check it by looking in the mirror everyday.
