HeadOn is a homeopathic topical headache relief product produced by Miralus Healthcare.^[1] Although intended uses are not listed on the website or in the commercial spot, the purported purpose of the product is to assuage head pains after being applied directly to the forehead.^[1] Chemical analysis has shown that the product consists of almost entirely wax.
