What is tuft hair that is standing up or growing in a different direction?

Cowlick

Explanation:

Tuft hair that stands up or grows in a different direction can sometimes be known as a "cowlick." A cowlick is hair that stands up straight or lies at an angle in a way that does not match the rest of the hair. This type of hair grows against the pattern that the rest of the hair follows, and can be difficult to style properly. The name comes from the cow's habit or licking its young.
