I'm glad that I'm not the only one wondering what on earth that "HeadOn" stuff which ye shall "apply directly to forehead" does - seems everyone has been hypnotized with the ads that are so bad they cause migraines.
Slate's Seth Stevenson confirms that the mystery stuff is for headaches - see: The mesmerizing ad for headache gel. So was the idea here to cause headaches, prompting me to rush out and buy the headon gel and apply directly to forehead? Devilishly clever!
