Cowlicks can be a nuisance, especially if you are rushing out the door. While they can be a natural occurrence due to your specific hair growth, they also commonly occur if it has been a while since you've taken a shower or bath. Your hair's natural oils create a substance in your hair to form cowlicks. For example, when you are asleep and your head is against a pillow, your hair can stick in an odd direction and the oil will help keep it there.
Wash and dry your hair.
Grab the cowlick between two fingers. Spray the base of the cowlick with hair spray. Spray the rest of the cowlick and hold it down flat to your head.
Heat a hair straightener and place your cowlick between the two plates of the straightener while it is still wet from the hair spray.
Pull the hair straightener down and twirl the hair with the straightener toward your head until the hair spray is dry.
Spray additional hair spray on the cowlick.
