Of course, like most advertising, they have to play on people's insecurities and suggest that if only you used their product you'd miraculously be happy.
There's an ad for hair transplants that is always playing on the TV at the gym I go to. They show a before and after of a guy. The "before" video is shot at a very unflattering angle. It makes him look like some kind of creepy pedophile. I guess the ad isn't working too well, though; there are a lot of guys, including much of the staff there, that have gone Sly.
