A cowlick appears when the growth direction of the hair forms a spiral pattern. The hair in a cowlick either stands straight up or lies at an extreme angle and seems to be always at odds with the style in which the rest of the hair is worn. They can show up anywhere. The most common site is in the crown. They also sometimes appear in front of the hair and back.
The term cowlick dates from the late 16th century, when Richard Haydocke used it in his translation of Lomazzo: "The lockes or plaine feakes of haire called cow-lickes, are made turning upwards." Also, the Latin word "calyx" is often pronounced this way and literally means a whorled look or appearance on something, and the "cowlick" always has a whorled appearance.
People tend to have at least two hairwhorls with one being dominant and clearly visible while the other is less obvious. In the center of the hairwhorl you can see the hairs protruding from the scalp. When combed against the grain of the hair, the hair in the center of the cowlick will stand up straight.
Cowlicks are more obvious in straight thick hair. In Asians with straight hair the scalp will show in the center of the whorl because the light penetrates the scalp. Both men and woman have cowlicks, but cowlicks can be covered by longer hair so the whorl is not visible.
