Mrs Hyppolyte Guilmard, of New York City, registered this label in 1899. According to Devner, this product was sold as late as 1912. I found Mrs Guilmard listed as a Hairdresser from 1867 through 1919. From 1885 until 1895, the business was called "H. Guilmard & Son." Devner said the product was "for removing dandruff and prevention of falling hair. It's possible that there was another product, because this one was a hair coloring. This bottle was also listed in the 7th Edition of Kovell's Bottle Price Guide. In connection with it, they indicated that it was from "Coral Gables, Florida." No bottle description available.
