Background: Hairdressers and barbers are among the top occupations to develop occupationally related nickel allergy. While nickel release has previously been detected in metal items in the hairdressing trade, metal items in the barber trade have not been specifically tested. This study screened for nickel release from metal tools in United States barber trade.
Methods: One hundred ninety-two metal tools from 12 barbershops in St. Paul, Minnesota, were tested with dimethylglyoxime test. An employee survey was conducted about each metal tool.
Results: Nickel release was detected in 10 of 192 metal tools (5.2%). Items with nickel release included one of 57 scissors (1.7%), one of 32 trimmers (3.1%), four of 13 barbershop chairs (30.8%), three of six cape clips, and one of one nail clippers.
Conclusions: Nickel release was detected in items unique to the barber trade. These items should be considered when preventing and assessing occupational nickel allergy in barbers.
