Abstract

Background: Contamination of hair dyes to heavy metals can threaten consumer’s health. We investigated the concentrations of some important heavy metals in hair dyes and evaluates their non-carcinogenic effects. Methods: The most commonly used hair dyes were determined through questioners and 32 samples were col-lected from the market of Tehran in 2014. The concentration of 10 heavy metals (Fe, Ag, Co, Cr, Mn, Ba, Cd, Cu, Pb, and Al) was determined using ICP-MS. Based on the obtained data from distributed questionnaires and Monte Carlo simulation, the exposure to the evaluated heavy metals was estimated. Besides, using hazard quo-tient (HQ) and chronic hazard (HI), the risk of non-carcinogenic effects of investigated hair dyes consumption was specified. Results: Results indicated the average concentrations of Al, Ba, and Fe as 0.54, 0.86, and 1.19 mg kg-1 and those of Cd, Cu, and Pb as 0.45, 61.32, and 185.34 µg kg-1, respectively. Pb with HQ of 7.46e-4 had the highest risk and Fe with HQ of 3.4e-6 had the lowest level of risk. Among the investigated dyes, the ones made by Iran (HI=2.8e-4) and the dark brown color (HI=1.93e-4) had the highest level of risk among all the studied samples. Conclusion: Two indices of HI and HQ showed that heavy metal contents in the investigated samples had not probable non-carcinogenic risks for the consumers of these products. © 2019, Iranian Journal of Public Health.
