Miracle cures for hair loss were sold by snake-oil salesmen in the Old West and they are sold on the World Wide Web today. A “cure for baldness” has long been a profitable claim for nostrums. The Old West snake-oil salesman might sell his product as a cure for baldness when his audience was made up mostly of men, and a cure for “women’s complaints” when his audience was mostly women. In the next town, he might sell it as a cure for rheumatism. The common thread in all of his claims is they are unverified by any scientifically acceptable evidence. We might believe that we are more sophisticated and knowledgeable than the citizens of a small town in the Old West who gathered around the wagon of the snake-oil salesman to hear his pitch. While it is true that we are probably more knowledgeable because there is more information to know about, it is also true that the purveyors of nostrums incorporate today’s advanced knowledge into their claims. The Nineteenth Century snake-oil salesman might base his claims on “secret knowledge” passed along to him by an ancient medicine man. The purveyor of nostrums today is more likely to use words taken out of context from the sciences of genetics and biochemistry to link his claims to scientific research. Buyers beware!
