IMO, a double blind independent study is the only way to go. Half the people go in so many times a week and get treated with the real laser brush, the other half gets the non laser brush (without knowing of course) It's the only way to make sure. It's expensive but the manufacturers who trust their products invest in such studies, it was done for Rogaine, Propecia ....
When they don't do such studies it means to me that they do not want the public to see the results.

HK500,

I will have to give a big AMEN on the need for a double blind study. I use the lasercomb for cosmetic reasons but I do not believe that it causes me to have MORE hair. It makes it look better, but that is it. I have one, so I use it, but would much rather have $500+ that they cost new to spend on my next 100 grafts.
