Looking like ChapStick for the forehead, HeadOn claims to relieve headaches without your having to pop any pills. In fact, its commercial featuring the most annoying voice-over ever (seriously, just watch) became more successful than the product itself. The Better Business Bureau says HeadOn "failed to provide any reliable testing to support its claims." Many doctors agreed there's no scientific basis that it actually cures headaches, although the company claims there's a homeopathic benefit. Still, we think the HeadOn commercials are more likely to prompt a headache than to cure one.
