In 1957, Dr. Fred Slack cut his thumbnail while working in his dental laboratory. Using aluminum foil, he created a platform to fix the nail with dental acrylic. Using one of the first methyl methacrylate monomers, he created what was most likely the first acrylic nail. His clever experiment would lead to the patent of the industry’s first nail form. In the late 1960s, Slack, along with his polymer and monomer chemist, developed many new nail technician-friendly polymer/monomer acrylic systems that continue to be used worldwide in the nail industry. In 1987, Slack and his son Rick decided to brand their successful formulations and created a company then called Nail Systems International.

To this day, NSI remains at the forefront of researching, developing, and manufacturing innovative monomers, polymers, oligomers, and other enhancement products for the professional nail industry. “We’ve built a tradition of creating breakthrough products that nail technicians want to use,” says Slack.
