The Menthol Argument
Several comments have claimed the product contains menthol, and present anecdotal material in its defense on that basis. The case for menthol efficacy is not without peer-review support:
 * Int J Clin Pract. 2010 Mar;64(4):451-6. doi: 10.1111/j.1742-1241.2009.02215.x.
 * Cutaneous application of menthol 10% solution as an abortive treatment of migraine without aura: a randomised, double-blind, placebo-controlled, crossed-over study.

In fairness, whether or not Headon contains any of the purported 'unlisted' ingredient at all, the abstract indicates that menthol does show evidence in terminating even migraines better than placebo in almost every test category. Naturally it's not in the manufacturer's interest to list something that would leave buyers preferring peppermint oil—containing copious amounts of menthol— available at any health products store for considerably less money.
