Well, according to H&W's price structure (appropriate since they did the work) Joe's work would have cost about $25,000. If you saw his before picture, it was money well spent.
I don't like Joe's "Penis Pills" either but I doubt Zix is a scam. The ingredients are all thought to be beneficial for hair loss and for years Joe wasn't even selling them.
I agree about Nicholson, but for most of his career he's only been a diffuse NW3, not bald. As for the other guys, how do you know they don't wear hair pieces?
