Low anterior hairline is a dysmorphic feature in which the frontal hairline which defines the top and sides of the forehead is unusually low. This can mean that either the distance between the trichion (hairline) and glabella at the midline is more than 2 SD below the mean, or that this distance is apparently (subjectively) decreased.[1][2][3]
