This study aimed to investigate the prevalence of head lice infection and external factors affecting the distribution of P.capitis in girls' schools in Garmsar city and east of Semnan province (Iran) from October 2017 to April 2018. This study was descriptive and analytical. A total of 850 students aged 7 to 16 from 14 selected girls' schools were screened for head lice. Data collection was performed using a standard questionnaire and physical examination of hair. A questionnaire was completed about the personal health practices and socio-demographic characteristics of students. Analysis was performed using the chi-square test and SPSS software version 18. The overall prevalence of head lice infection in Garmsar city was approximately 33.17%. This prevalence in elementary and middle school students was 41.66% and 12.8%, respectively. There was a statistically significant relationship between pediculosis capitis and the occupation of mothers with the level of education, father's occupation, and the presence of health teachers in schools, bathing intervals, combing intervals, access to health services, and school score.
