In the books, Hermione is described as having bushy brown hair and brown eyes. Her front teeth, already very large, grow uncontrollably in Goblet of Fire after she is hit by a spell cast by Draco Malfoy. Madam Pomfrey attends to her in the hospital wing and, at her request, shrinks the teeth down to a normal size for her mouth. Hermione believes this would upset her parents.
