My Hair Problem

 When I was little, my mom fixed my hair in a stylish way. It was long and thick with crinkles made from the crimp iron she used. I went to school and showed it to my classmates. Afterschool, I came home and when my mom looked at my hair, she said I had big bald spots in the scalp and around the edges. She accused me of somebody yanking my hair out, but the truth is... I don't know what happened. If some girl pulled out plugs of my hair, I would've hollered because my hair is attached to my scalp! But my mom didn't believe me, all she noticed was bald spots in my head and around my edges. She also knew the difference between cut hair and hair pulled. I knew then I was fighting a losing battle, so I upheld her accusation by lying to her that a jealous girl pulled my hair out, to keep her from jumping down my throat. My mom knows what it's like to be in a black school- if a black girl has pretty long hair, other girls will do anything to destroy it! I remember one time when a girl yanked my hair for real, but she didn't pull it out- just an act of pettiness. Can somebody tell me what was wrong with my hair? Because I didn't have a perm at that time.
