The purpose of this study was to suggest the knowledge and scientific information of the damage and improvement according to hair coloring manipulation. The study investigated variations of mechanical, nourishment(amino acid cystine) shape of cuticle characteristics according to hair coloring during 40, 50 minute. The results were as follows; Tensile strength was decreased variations of 6.62%, 13.68%, extension rate was increased variations of 10.58%, 12.28%, thickness was increased variations of 9.15%, 15.64% in 40 min. and 50 min. hair coloring. Content of amino acid cystine was lowered variations of 23.00%, 30.49% according to time of manipulation. A shape of cuticles was disfigured and brocken by reason of hair coloring manipulation.

The purpose of this study was to suggest the knowlege and scientific information of the damage according to the heavy metal exposure level of hair coloring manipulations. The study was investigated variations of the heavy metal contents(Pb, Zn, Cu, Mn, Fe, Ni) in hairdye and human hairs by 1 and 2 times of hair coloring manipulations. The results were as follows; 1. Mean heavy metal contents in colorant of hairdye were 0.250ppm(Pb), 33.650ppm(Zn), 0.800ppm(Cu), 0.675ppm(Mn), 31.050ppm(Fe), 1.700ppm(Ni). In oxidant of hairdye, It were 0.225ppm(Pb), 35.450ppm(Zn), 0.575ppm(Cu), 0.075ppm(Mn), 16.600ppm(Fe), 1.500ppm(Ni). 2. Mean heavy metal contents were 2.950ppm(Pb), 29.000ppm(Zn), 9.400ppm(Cu), 1.075ppm(Mn), 40.775ppm(Fe), 1.950ppm(Ni) in virgin hairs, 3.025ppm(Pb), 40.250ppm(Zn), 9.650ppm(Cu), 1.350ppm(Mn), 42.900ppm(Fe), 2.200ppm(Ni) in 1 time of coloring hairs, 3.350ppm(Pb), 51.650ppm(Zn), 10.950ppm(Cu), 1.475ppm(Mn), 44.350ppm(Fe), 2.225ppm(Ni) in 2 times of coloring hairs.
