High anterior hairline

High anterior hairline is a dysmorphic feature in which the frontal hairline which defines the top and sides of the forehead is unusually high. This can mean that either the distance between the trichion (hairline) and glabella is more than 2 SD above the mean, or that this distance is apparently (subjectively) increased.
