A three-year-old child has sparse hair, and after being shaved multiple times, the hair only grows out short. The child’s grandfather insists on shaving it again, but I think it’s not very nice for a little girl to go to school with a shaved head. The grandfather believes that ’like hair and beard, the more you shave, the thicker and fuller it gets.’ Is this view correct?
