when do babies get their eyebrows
Baby's Hair in the Womb. Babies start growing hair before they are even born, Kids Health says. By the 14th week of pregnancy, babies in the womb develop a layer of lanugo, which is a soft, fine hair that starts on his face and eventually covers his entire body. Hair starts to grow on a babyâs head as early as the 30th week of pregnancy and, by the 32nd week, the baby develops eyelashes and eyebrows.
