Lanugo helps protect your babyâs skin from drying out in utero. The constant immersion in amniotic fluid could chap and irritate a babyâs delicate skin. Dr. Steven B. Hoath and fellow researchers at the Skin Sciences Institute, researched the role of vernix and lanugo.
During human development, the lanugo grows on fetuses as a normal part of gestation, but is usually shed and replaced by vellus hair at about 33 to 36 weeks of gestational age.t is replaced by hair covering the same surfaces called vellus hair, but this hair is finer and more difficult to see. The more visible hair that continues into adulthood is called terminal hair. This forms in specific areas and is hormone dependent.
