Is my nail technician licensed?

Nail technicians are required to keep their license visibly posted at their work station. Most states require that there be a photo of the license holder on the license. If you do not see a license, including a salon license, ask to see it. If this request if refused, leave the salon and report it to the local regulatory authority. Unlicensed practice is illegal. You can see the complain.info section here for state board web site links, many state boards have searchable data bases online.
