Although the hijab has recently attracted much attention from social scientists, the discrimination experienced by hijabis has been insufficiently investigated. Data are difficult to obtain, partly because surveys usually do not have items on this practice and victims are difficult to reach. However, field experts, namely active agents in governmental racism-prevention institutions and in Muslim associations, can provide rich insights into processes of discrimination. Based on an analysis of semi-structured interviews, I answer the following question: how do governmental and non-governmental experts describe discrimination against hijabis in Switzerland? The results reveal that, according to the experts interviewed, the hijab is the most important marker leading to processes of discrimination; this discrimination takes a variety of forms and affects a wide range of life domains and profiles of hijabis; such discrimination leads to a segregation of the social space of hijabis; many women are unwilling to report discrimination to governmental services for different reasons.
