Honestly, when you get to that degree of hairloss (>NW4) the only solution which will give you a full head of hair is a system. Meds are of little help, and transplants look pretty ropey spread out over that much empty space.
I have been wearing a system for a few years now, and have been really happy with it. Of course there is a bit of maintenance and expense, but they are quite manageable, and it has allowed me to enjoy my young prime years with a nice head of hair, which has helped my confidence in my social and work life. You can get great looking systems now for under $300 if you know where to look, and they are pretty much completely undetectable. This solution is not for everyone, but it is worth investigating if your hairloss is bothering you.
