Step-by-step explanation:
The silken, fine hair that is present on a baby's body at birth is known as lanugo. This type of hair is usually colorless and covers the fetus starting from around weeks 17-20 of gestation. Lanugo serves as a protective layer, but as the fetus develops, this hair is typically shed just before birth. Babies who are born prematurely might still have some lanugo present on their bodies.
However, it usually disappears within the first month after birth, as the newborn grows. The replacement for lanugo is called vellus hair, which is the fine hair that continues to serve a protective function after the lanugo has been shed.The term 'lanugo' refers to the baby-fine, silky hair that covers a fetus's body and is usually shed close to the time of birth, though it may still be present on premature babies.
