Lanugo is a fine, soft hair that typically covers the body of a fetus during development, usually appearing around the fourth or fifth month of gestation. It serves to help regulate body temperature and protect the skin in the womb. While most lanugo is shed before birth, some premature infants may still have it at birth. In adults, lanugo can sometimes occur in response to certain medical conditions, particularly eating disorders.
