With consumer safety topmost on so many people’s mind, it’s nice to know you can put clients’ fears to rest on one score: The polish you are painstakingly applying to their nails is safe, no matter how many others used the same bottle previously.

“Organic solvent-based nail polish products (e.g. nail polish, lacquers, enamels, varnish, base coats, and top coats) provide a hostile environment that prevents microbial contamination even when the product and brush are used repeatedly,” says industry chemist Doug Schoon, co-chair of the PBA’s Nail Manufacturer’s Council (NMC). Several independent scientific studies conducted by the NMC demonstrate that organic solvent-based nail polish products aggressively kill any microbes that may be inadvertently picked up by a nail polish brush. This means repeated use of nail polish products does not pose an infection risk for salon clients.
