Celebrity Products

I was wondering if anyone knew what type of hair products Celebrites use. Especially for men, as I am convinced that guys like Ben Affleck uses a pretty good line since his hair seems to get better in every movie he stares in (watch good will hunting and compare it to paycheck....pretty drastic). Anyhow, I am just wondering as I want to give it a try and see if more expensive top of the line shampoos do the trick but i don't know where to start. I just need to know some of the lines out there. Sorry for the trouble and thanks again.

I don''t necessarily think the post was off topic. At least it wasn''t just a question about what topics to use or what topics do people recommend. I have to admit I like to know what certain celebrities with great hair use. I''d also like to avoid the hair products and styling lines of celebs with awful hair. Like, if Courtney Love uses a particular product, I could do without using it (lol), but I wouldn''t mind hearing how Liv Tyler or Sarah Michelle Gellar keep their hair looking great.
