Abstract
Scalp hair samples were collected for the assessment of some essential and non-essential metals using atomic absorption spectroscopy (AAS). A total of 8 subjects were randomly collected comprising of 4 male non-dyed hairs and 4 female dyed hairs. In all the samples analysed, the effect of hair dyeing on essential and non-essential metals contents were evaluated. The result showed that concentrations of metals are higher in female subjects with dyed hair and differ significantly (p<0.05) with metal male non-dyed hair. The findings revealed that both essential and non-essential metals were introduced from the dyeing cream used. Dyeing of hair can therefore change the content of the metals in hair. Due to the growing usage of dyeing creams, it is imperative to regulate and monitor its application.
