Description
Black and white 5″ x 11 1/2″ ad with the confusing explanation “Sensational Scientific Discovery explains why Listerine Cures Dandruff”. I have to think that this was just another way for the company to make money. The ad advertises that “Once or twice a day, just douse full strength Listerine on your scalp; then massage vigorously and persistently until every hair is bathed in soothing, health-promoting antiseptic”. The germ they have identified as the cause of dandruff is Pitrosporum ovale and Listerine had been proven to fight this germ.
