Why didn't Joetta like Byrons hairstyle Whatsons go to birminham?

Joetta didn't like Byron's hairstyle because she found it to be unkempt and overly flashy, particularly because he had chosen to get a conk, which she believed made him look silly and was not appropriate for a boy. Additionally, she was concerned about how others would perceive him, especially during their trip to Birmingham, where she wanted the family to present a good image. Joetta's disapproval reflects her desire for her brother to maintain a respectable appearance.
