If you're just starting to lose your hair, propecia by itself should work fine for you, along with Nizoral shampoo.
However you do retain the option to try Rogaine by itself. It doesn't have the % effectiveness that Propecia does and we typically recommend it for those seriously in need of restoring lost hair, not those just starting to thin on the hairline ... but you can give it a try.
It works *best* on the top and back of the head, and was only tested there in the FDA trials, so they were only allowed to report that it works there, on the box.
Make sure you get Nizoral shampoo and use it once every 3 days, and expect your hair to look worse before it looks better. Rogaine can cause shedding that can last a few months. Ride it out. Use Folligen lotion to handle any irritation you may get from the Rogaine.
