Let me recommend you something really fun: Improv classes. I took only a 6 weeks class and it was great.
1) You'll be forced to be out of your comfort zone, which might be one of the reasons you are not meeting people: its comfortable not to (I've been there).
2) You'll be performing truly ridiculous acts, in its hilarity you'll likely form some bonds with the other students. Take the advantage to go for some drinks after.
3) Improv is all about being present, in the moment. Guess what, wooing women is the same.
4) You'll learn a thing or two about interpersonal relations. Which is good.
Now, the best way to meet women that you want to seriously date is through friends, since you claim you don't have a social circle, I would recommend that you focus on building one. So, in your improv classes, invite these new acquaintances for a pint of beer.
Finally, women, in my experience, are not as fixated in physical traits as we men are. Thus, I would not worry about your hair loss that much, and work more on improving social interactions. It is, however, important that you keep yourself presentable: nice clothes, brushed teeth, get some lotion, decent haircut.
