I keep on seeing those stoopid television commercials for HeadOn: “Apply directly to the forehead!” The commercials feature plenty of folks praising HeadOn for its effectiveness (“it really works!”). Great. But, works at what? I thought it was kind of strange that they went to the trouble that “it really works great”, without telling you what it actually does that it does so well. I had no idea. Do you?
I just saw the commercial again a few minutes ago, and finally worked up the curiosity to look it up on Wikipedia, and finally found out what it does: nothing. It doesn’t do anything. Its manufacturers want you to believe that it treats headaches, but they can’t actually claim that on TV, because there’s no evidence that it’s true.
