Hair on the back of the head usually grows in a circular flattened pattern from a central point; this can also occur on facial hair. The definition of a whorl is hairs that rotate round an axis. The point where the hair whorl is found is the spot where the hair changes direction. On top of the head hair grows to the front, on the back of the head it grows towards the nape and hair grows to the left and right side of the head on the sides of the head. The hair whorl can be in the center of the head but it can also be located to the left or right side of the head. In the very center of the scalp it will be visible because the hair lies flat.
