after emailing the doc and receiving no reply i decided to do some more searching...recently in the news german researchers claim that the substance is caffeine. im guessing this is what the doc was talking about although i cant say for sure since i missed that radio program...

Yes, now that you mention it, I heard that on the national news.

Yes, the common substance that he mentioned is caffeine. He warned that he did not mean to imply that large amounts of caffeine should be taken internally, though, because too much caffeine is harmful and can even cause death.

i wonder if it really works? i mean over the years there has been so much snake oil...and if products do work...its only very minimal. i wonder if caffeine would grow your hair significantly.
