Ive been taking minoxidil (Regaine) for the past 6 months and while I believe that Ive had a few hairs growing, it hasnt covered my patch completely, and im only 25, so if you have significant hair loss and have done so for years I expect it not to work.
Minoxidil may work, but not as effectively as you think. Its expensive unless you buy the american version from ebay which is really cheap. The sellers ID is outletamerica . They sell the Kirkland brand of minoxidil, different name but same product, much cheaper at approx �22 for 4 months supply. I believe that is the cheapest anywhere! I recommend them.
