Answer:
Abigail had developed lanugo, a fine silky hair covering Abigail's torso, face and arms.
Step-by-step explanation:
People who have anorexia commonly develop lanugo, a fine, light hair on the chest, arms, back, and face. Since anorexia causes people to be fat depleted - too thin -, their bodies react by creating the extra hair in an attempt to keep them warm. Lanugo is normally developed in fetuses and new-born babies, but only appears in adults under conditions such as the ones caused by eating disorders.
