Reuben P. Hall, of Nashua, New Hampshire was the original inventor of Hall's Vegetable Sicilian Hair Renewer. In 1865, he sold the right to this product to J. C. Ayer. After a couple of years, Hall had a change of heart and started selling the brand again. In 1870 there was a court case upholding Ayer's rights to the trademark. This preparation was for sale from 1870 until at least 1873. Hall thought that he could manage to get away with it by calling it an "Improved Preparation." Unfortunately, when he sold the rights to his original preparation, he also sold the rights to using his name in conjunction with a hair product. As a result, there was another court case in 1873 that mentions the "Improved Preparation." The original ruling was upheld in this case as well.
