The work of hairdressers includes washing, coloring, bleaching, permanent waving, conditioning, and cutting scalp 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 and from chemicals 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 roadway. Personal exposures to VOCs and PM10 were related to indoor concentrations of beauty shops, respectively. According to questionnaire, hairdressers responded sore throat, eye irritation, and nervousness as health effect symptoms. Conclusively, users as well as workers in beauty shop might be highly exposed to air pollutants from indoor sources and outdoor sources. Therefore, proper methods should be prepared to improve the indoor air quality in beauty shop.
