Recently, there are many research of musculoskeletal disorders in manufacturing industry because of increasing interest of that disorders, but the research is still lacking in the small business and service industry. So we researched relationship between working characteristics and subjective symptoms associated with musculoskeletal disorders by get information of 145 hairdresser about working hour, work record, position and working pattern. The results of this research show that there are many musculoskeletal disorders of hairdressers' neck, shoulder, arm, knee and also close relationship between working characteristics and subjective symptoms associated with musculoskeletal disorders. Besides, some parts of subjective symptoms have an effect on other parts of body. This information contributes to future reference and a precautionary measure about musculoskeletal disorders for hairdressers.

The results of this research show that there are many musculoskeletal disorders of hairdressers' neck, shoulder, arm, knee and also a lot of relationship between working characteristics and subjective symptoms associated with musculoskeletal disorders. Besides, some parts of subjective symptoms have a effect on other parts of body. This study will contribute to using information and a precautionary measure about musculoskeletal disorders for hairdressers.

The work of hairdressers includes washing, coloring, bleaching, permanent waving, conditioning, and cutting hair. Hairdressers are subjected to a number of physical and toxicological hazards. The toxicological hazards are those resulting from exposure to a wide range of chemicals that are usually classified active processes. In this study, twenty beauty shops were selected to assess the exposure to indoor air pollutants such as VOCs and particulate matter (PM10) during one month from September 1 to September 30, 2003. Indoor air quality of beauty shops might be worse by vehicle emissions because the beauty shops were generally located near roadways. Personal exposures to VOCs and PM10 were related to indoor concentrations of beauty shops. According to the questionnaire, hairdressers complained of sore throat, eye irritation, and nervousness as physical symptoms. The measured mean concentrations of respiratory particulates were 30.5ng/㎥ in indoor, 30.5ng/㎥in outdoor and 44.0ng/㎥ on personal levels. The personal concentration was found higher than indoor and outdoor concentrations. The heavy metals mean concentrations were shown as indoor (Na>Zn>Cr), outdoor (Cr>Zn>Pb), and personal (Na>Cr>Zn) levels. Conclusively, customers as well as workers in the beauty shops might be highly exposed to air pollutants from indoor and outdoor sources. Therefore, proper management should be taken to improve the indoor air quality in beauty shops.
