Outline of Final Research Achievements	In this study, we investigated the state of cranial bacterial contamination, and developed a hair-washing method for effectively eliminating bacterial contamination. S.aureus and multiple CNS were detected from cranial regions, demonstrating distribution of staphylococci living in the hair and scalp. With regards to changes over time in patients and healthy adults, we found that increase in bacteria was slow in healthy adults even 3 days after hair-washing, whereas bacteria tended to increase rapidly in patients. Furthermore, comparison before and after hair-washing showed that bacteria were detected in more sites at higher rates after hair-washing compared to before hair-washing, suggesting a possibility that bacteria were dispersed over the entire head after hair-washing. Therefore, we focused on the amount of hot water used during rinsing and the use of hands during hair-washing to develop a method of hair-washing that is effective for eliminating bacteria.
