George R. Sims, of London, registered this brand name as a trademark in 1897 (TM #30,912). The trademark consisted of the word "Tatcho" over his signature. He said he had just started selling the preparation that year. In 1912, the British Medical Association examined this preparation, and found it to contain 2.7 parts Borax, 2-5 parts glycerine, and small parts of quinine, formaldehyde, alcohol, and perfume. They also included the words below (from the label) in their article.
The certain, trusty, genuine, right, honest, hair grower. There is no other. Without Tatcho loss of hair is inevitable, but Mr Ge. R. Sims has altered all that. If your hair has become scanty or grey get Tatcho today. It will bring back the hair of your youth, make a new being of you, and give you a new grip on life.
If you look at all the packaging you will notice that this is called a "restorer," "renewer," "tonic," and "dressing." The box I have for the product says there was a "oily" and a "non-oily" formula.
