You should know that hair can grow in different patterns
Some people have uneven hair growth patterns that can be caused by cowlicks, double crowns, whorls, or a combination of these characteristics. Cowlicks are portions of hair that grow strongly to the left or right usually on the crown or at the front of the hairline and sometimes at the nape of the neck. Double crowns are two areas of hair close to each other that have hair growing in opposite directions. Whorls are sections of hair that grow in a circular pattern often at the nape or the crown. It is important to know that everyone's hair does not grow in the same way or at the same pace. If you are trying to grow your hair longer to obtain a particular style, you may have to endure uneven hair growth as you strive to reach your goal.
