Cowlicks, by definition, are unruly tufts of hair that grow in a different direction from the rest of the hair. However, finding an antonym for cowlicks may prove to be difficult as there really isn't an opposite word that would fit this description. In essence, the opposite of cowlicks would be smooth, even hair that flows uniformly in one direction. So, one might use words like sleek, polished, or tidy to describe the opposite of cowlicks. Nevertheless, it's important to note that cowlicks can add character and uniqueness to one's appearance and should be embraced rather than shunned.
