Advice for a newbie

[Anders]

Hi,

I'm 34 and starting to notice my hair is getting a lot thinner. I've been looking at several of the recommended products but its a bit of a minefield out there. So can any give me some advise on the following questions.

Propecia anyone used it without side affects?
Anyone got any success with natural treatments or applications?
Saw Palmetto any good?

Thanks
Anders
