Infusium 23 was developed and distributed by Duart Manufacturing Co. Ltd., a small company owned by brothers Jesse and Leon Markel, their wives, and one loyal employee. Beauty salons throughout California eagerly welcomed Duart Manufacturings hair care line, which featured a unique Pro-Vitamin Hair Treatment (VHT) and Leave-In Treatment. These exceptional products restored hair that had been damaged by chemical processing and styling. Word-of-mouth support from highly satisfied stylists and clients turned Infusium 23 into the leading leave-in treatment for damaged hair a reputation that still stands today. As demand for the product grew, Duart introduced Infusium 23 to the professional salon industry. That was in 1973. By 1986, Infusium 23 became available in retail outlets across the United States. Today, it's found in more than 20,000 stores throughout the U.S. and Canada. Herbspro.com is proud to carry the entire range of this fine brand.
