Fetal body hair, also known as lanugo, is a fine, soft hair that covers the body of a developing fetus, typically appearing around the 16th week of gestation. It serves to provide insulation and help regulate the fetus's body temperature, as well as potentially aiding in the attachment of the vernix caseosa, a protective waxy coating. Lanugo usually begins to shed as the fetus approaches term, with most of it gone by birth, although some premature infants may still have remnants of it.
