Dr. Steiner: … We need to see to it that we find some way to get some money. A number of things are in progress, but they are not going very quickly. We have something very promising in Dornach, a shaving soap and the hair tonic, “Temptation,” but we can’t get that going quickly enough. We cannot invent things fast enough to have a gymnasium, a eurythmy room, and a music room in the fall. Before we have that, all the baldies would have to grow hair.
A teacher: At the risk of my wife not recognizing me, I want to try it.
Dr. Steiner: Our eurythmy ladies have already decided to try the hair tonic so that their mustaches grow. Then they will shave them off with the shaving soap. The thousand-mark bills will grow on peoples’ heads.
 The German word is Verlockung, which means “enticement,” “temptation,” allure,” or “seduction,” but its root word is lock, or “hair.” The message was that this hair tonic would “tempt your hair to grow” (back, we presume). — TRANS.
