Female pattern hair loss affects the central scalp, sparing the frontal hairline. The temporal area can also be affected by hair loss. We investigated the degree of temporal hair loss and correlation of other sites of scalp hair loss in Korean female pattern hair loss patients. A total of 109 women with female pattern hair loss were enrolled in this retrospective analysis. We measured hair density and thickness in five scalp sites including the frontal, vertex, occipital and bilateral temporal areas by phototrichogram. Frontal and vertex area hair loss were classified according to the Basic and Specific (BASP) classification, and temporal scalp and occiput areas were also assessed. Eighty‐nine patients showed temporal hair loss. The mean of the hair density was lowest in the temporal area among all scalp areas. Total and thick hair densities of the frontal scalp were correlated with those of the vertex, temporal scalp and occiput in descending order, and hair thickness of the frontal scalp was more related with that of the temporal scalp than the vertex. In this study, temporal involvement is evident in female pattern hair loss. We suggest that temporal involvement should be added to pattern hair loss classification, especially BASP classification.
