Determination of lead in various brands of hair dyes samples by using atomic absorption spectroscopy

Abstract

The concentration of Lead (Pb) present in hair dyes potentially toxic and a higher degree of information related to oxidative/non-oxidative dyes. Human exposure to lead (Pb) for a longer period gives rise to major diseases like neurotoxicity, carcinogenicity which manifests a serious health problem. It is known that lead is present in cosmetic products like lipsticks, soaps, face creams, hair gel, hair dyes. Their by-products get absorbed in the bloodstream through the skin and roots of the hair which holds a harmful effect. This study is focusing on the assessment of lead, contamination in hair dyes commonly used by the Indian population. The samples of different brands of hair dyes were examined using Atomic Absorption Spectrophotometry. The results of the study indicate that the concentration of lead exceeds the maximum permissible limit set by the World Health Organization and Food and Drug Administration (FDA).
