He examined my scalp, and told me that I had dandruff in my hair, and that he would give me a prescription which would remove this dandruff and cause my hair to stop falling out. He charged me ten dollars for the visit, which in those days was more money than it is at present. Being of an inquiring turn of mind, I tried to get my money's worth by learning what there was to learn about the human hair. I questioned this gentleman, and he told me that the hair is a dead substance, and that its only life is in the root. He explained that barbers often persuade people to have their hair singed, to keep it from falling out, and that this was an utterly futile procedure, and likewise all shampooing and massage, which only caused the hair to fall out more quickly. It was better even not to wash the hair too often. All that was needed was a mixture of chemicals to kill the dandruff germs; and so I had the prescription put up at a drug store, and for a couple of years I religiously used it according to order, and it had upon my hair absolutely no effect whatever. So here was the best that medical science could do. But still, I did not want to be bald, so I went among the health cranks--people who experiment without license from the medical schools. Also, I experimented upon myself, and now I know something about the human hair, something entirely different from what the rich and successful "consulting dermatologist" taught me, but which has kept me from becoming entirely bald: First, the human hair is made by the body, and it is made, like everything else in the body, out of the blood-stream. It is perfectly true that the dandruff germ gets into the roots, and makes trouble, and that the process of killing this germ can be helped by chemicals; but it does not take a ten-dollar prescription, it only takes ten cents' worth of borax and salt from the corner grocery. (Put a little into a saucer, moisten it, rub it into the scalp, and wash it out again.) But infinitely more important than this is the fact that healthy hair roots are a product of healthy blood, and that unhealthy blood produces sick hair roots, which cannot hold in the hair. Most important of all is the fact that in order to make healthy hair roots the blood must flow fully and freely to these hair roots; whereas I had been accustomed for many hours every day of my life to clap around my scalp a tight band which almost entirely stopped the circulation of the life-giving blood to my sick hair roots. In other words, by wearing civilized hats, I was literally starving my hair to death.
