Legislation that affects nail technicians tends to be in the realm of licensing, reciprocity, sanitation guidelines, and public safety. There have been several laws in the past decade surrounding pedicure safety (especially as it relates to certain kinds of equipment) and chemicals in products.
There is really no national legislation guiding the practice of nails (in fact, some states do not regulate nails). The Professional Beauty Association (PBA) has been a legislative advocate for the beauty industry for years, focusing on issues of taxation, cosmetology education, and chemical issues. The photo shows OPI's Eric Schwartz at a "Welcome to Our World" event organized by the Professional Beauty Federation (PBF) where cosmetologists offers Congressional staffers beauty services in an effort to help them understand "our industry." Congressman Henry Brown of South Carolina seems to be enjoying his manicure.
