I had indeed been researching the topic of hair loss myself and what you posted falls very much in line with what I came to believe and am expecting.
I was thinking about getting some Revivogen, a topical hairloss wash. It seems to be quite natural and safe and it is supposedly the most effective treatment available. The only thing is that I would not want to start using this stuff and then not even know if my results are coming from the Revivogen or from the liver cleanses. :P
I think I'll closely monitor my hairline and look for slight improvements from just liver cleansing... then if I can see that it is making ANY difference, I can just speed the whole process up with some Revivogen. :D
