Detailed explanation-1: -Month 5 – Week 20-24 Hair growth continues on the baby’s head and body. The shoulders and back become covered with a thin hair called lanugo. A thick substance, called vernix caseosa, covers the skin to keep it protected from the exposure to amniotic fluid. This layer will shed before the baby is born.
Detailed explanation-2: -A baby’s hair starts growing in the womb during 14th and 15th week of pregnancy and this phenomenon occurs in two cycles. Shedding and then regrowing. There are no new follicles that appear after the birth of the child.
Detailed explanation-3: -All of the 5 million hair follicles of an adult human form during the fifth month of prenatal development, coating the fetus with a downy layer called lanugo. In most newborns, the lanugo has receded beneath the skin surface, perhaps leaving a bit of fuzziness on the ear tips or elsewhere.
