A cowlick is a section of human hair that stands straight up or lies at an angle at odds with the style in which the rest of an individual's hair is worn.[1][2]
The most common site of a human cowlick is in the crown, but they can appear anywhere on the head. They also sometimes occur in the front and back of the head.[citation needed]
The term "cowlick" dates from the late 16th century, when physician Richard Haydock used it in his translation of Gian Paolo Lomazzo: "The lockes or plaine feakes of haire called cow-lickes, are made turning upwards."[3]
