How did miss trunchbull pull the girls hair?

Miss Trunchbull would pull the girls' hair as a form of punishment or intimidation. In Roald Dahl's "Matilda," she is depicted as a tyrannical headmistress who uses physical force to assert her authority. Her actions are often exaggerated to highlight her cruelty, such as grabbing a girl by the pigtails and swinging her around. This behavior emphasizes her tyrannical nature and the fear she instills in the students.
