hey man, as far as Finpecia, go with what works. All the studies I've read about propecia/finpecia have been positive. I wouldn't consider it for a first option, but it is an option.
as far as saw palmetto, my point was not that all hair tonics or hair sprays or whatever you want to call them... it was not that the only ones that work, but that the ones that work tend to share the same ingredients. I have read studies on saw palmetto, and that's why I would trust a hair remedy with that in it.
I am not familiar with the hair products you cited. What made you decide on those as opposed to the thousands of others?
