HeadOn is the brand name of a topical product claimed to relieve headaches. It achieved widespread notoriety in 2006 as a result of a repetitive commercial, consisting only of the tagline "HeadOn. Apply directly to the forehead", stated three times in succession. Originally sold as a homeopathic preparation, the brand was transferred in 2008 to Sirvision, Inc., who re-introduced the product with a new formulation.
