Human hair serves as a unique biomonitoring tool due to its ability to accumulate the trace elements over time, reflecting the environmental exposures and dietary intake. This study employed the Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to analyze the elemental composition of human hair samples of different colors-red, black, blonde and gray. The results revealed varying levels of essential and toxic elements across different hair types, indicating the potential exposures to the environmental pollutants. Notably, red and blonde hair exhibited higher concentrations of Cu, Fe, and Pb, which could be attributed to the environmental and dietary sources as well as the presence of metals in the hair coloring products. Gray hair also showed elevated Cu and Pb levels, possibly reflecting both environmental contamination and dietary intake. Non-washed hair generally displayed higher metal levels compared to washed samples, suggesting a prolonged exposure and accumulation. These findings highlight the utility of hair analysis as a non-invasive method for assessing the long-term metal exposures and their implications for human health.
