Ethel later offers to help Mildred again in her hair predicament. She formulates a potion that she claims will restore Mildred's hair to its rightful length. Mildred applies the potion that night and just when she is dropping off to sleep, her hair starts growing longer and longer by the minute, engulfing the whole school. Miss Hardbroom comes to investigate, states that Mildred is having "a bad hair day", manages to stop the hair growing and cuts it to its rightful length and vapourises the swathes of hair that had engulfed the whole school.
