That head-on commercial is HORRIBLE - and could be responsible for headaches. Maybe that's their goal.
I also HATE the Vonnage commercial with the stupid repetitious song.
I hate this commercial to the max. If I had the worst headache in the world, I would not purchase this product just because of the advertisement.
Any advertisement consultant will tell you that, even though you remember the ad, do you remember it in the positive light or in the negative light. If an ad strikes you in the negative, you will remember it and reject it out of hand.
What is the Head-On commercial about? I saw part of it once, and I was clueless... still am.
Go to headon.com and you'll look in vain for any statement that it's a headache remedy
