fine, soft, unpigmented hair resembling fetal hair
Lanugo-like body hair refers to fine, soft, and often unpigmented hair that resembles the lanugo hair found on fetuses. In adults, this type of hair can appear due to certain medical conditions, such as anorexia nervosa or hormonal imbalances, where the body reverts to producing this fetal-like hair as a protective mechanism.
