I have read the answer to an posted question on hair loss. 

http://answers.google.com/answers/threadview?id=93413

This mentioned two products that looked like promising treatments. 
Fabao and Cato.


FABAO
The claims are extraordinary, and as such I am highly sceptical.
However, like most men who are losing their hair, I am willing to
investigate anything!

I have done some research, but wonder if you can find any evidence
that these products indeed work, from reliable sources. Or if you can
cast further doubt on their validity by suspicious errors etc.

For example, I looked at the domain www.fabao.com and found that it
was aparently created in 1997. Does this make its legitimacy more
likely?

I have read that the inventor of fabao won a prize at the 38th
Brussels Eureka World Fair, but cannot find out any official
information to back up this claim, or what merit winning this prize
actually is.

I have also read that the inventor is investigating setting up
factories in Australia (back in 1997 see
http://www.fabao.ch/press/en.aspx) and the US. Does that mean that
clinical US trials would have to take place, or could he just sell the
product as a nutritional supplement like any other? Has he actually
set up any factories at all?


CATO

Similarly the other product, Cato, supplied by cloverleaf makes bold
claims. I am more suspicious of this company as they appear to have a
wide range of products that appear unlinked and all make very bold
claims.
I am also very suspicious of their research headquarters photograph,
which to me looks like a C.G.I., although I may now be too suspicious.
Also why are most of the researchers in their photos bald!

Please help me to confirm or deny the truth in these claims. 
Are there any products out there with actual independent clinical
trials (other than finesteride and minoxidyl)

Here's a newsgroup thread about Fabao:

A quote from the link above:

The U.S. Federal Trade Commission flatly states, "there is no
over-the-counter cream, lotion or device that can induce new hair to
grow or cause hair (thinning hair) to become thicker." Hair-growth
remedies and other health frauds squander billions of dollars, the
agency warns.
