You could always shave your head and wear wigs when you go outside or when you are around people. I'm serious.

What ever you do I'd highly advise against taking Finasteride, I've heard it screws with your body chemisty and hampers Androgen production.

Minoxidil is helpful as a side support therapy, but a lot depends on your specific clinical situation.
Do you use shampoo frequently? Are you very stressed recently?
What I recommend is that you visit a dermatologist who can suggest what you really need to buy or do to get better.

What about Rogaine?
