The present study is carried out to measure zinc and cadmium in twenty samples of anti-dandruff shampoo products commercially available in the localcosmetic markets in Libya. Detection of zinc and cadmium were done by Flame Atomic Absorption Spectrophotometry (FAAS) method. The results showed that cadmium concentration ranged between 0.017 and 9.37 mg.kg−1 while zinc concentration ranged between 25.9mg kg−1and 8300mg.kg−1. These measurements indicated that cadmium and zinc contents in the investigated samples were higher than WHO limits; suggesting that chronological use of these shampoo products would impose serious health risks to human users. Therefore, quality control and concentration optimism should be implemented to assure the safety of cosmetic products. This also can be achieved by improving the processing and manufacturing practices in the industry.
