Confocal micro X-ray fluorescence is an effective method for obtaining information about elemental distribution inside the sample. A hair has trace elements such as Ca and Zn, so it is possible to examine deficiency of these elements and whether we take harmful metal by scanning one's hair. Then, we tried obtaining elemental map at any position and revealing information about elemental distribution from the hair root to top by applying confocal micro XRF. We also investigated the possibility about invasion of element from outside by analyzing fluorescent X-ray intensity of hair on surface and at center in specific cross section. In the hair applied a permanent wave, it became clear that it receives strong contamination from the outside.
