lead cadmium copper zinc iron calcium hair dyeing metal accumulation human hair

TLDR Smokers and people with dyed hair have higher levels of certain metals in their hair.

The study investigated the concentrations of lead, cadmium, copper, zinc, iron, and calcium in human hair, examining how these levels varied with gender, age, smoking habits, and hair dyeing. The research aimed to understand the impact of these factors on the accumulation of metals in hair. It was found that metal concentrations differed significantly based on these variables, suggesting that personal habits and demographic factors influenced the presence of these elements in hair. The study provided insights into how lifestyle and biological factors could affect metal accumulation in human hair.
