During pregnancy, a baby’s body goes through a remarkable transformation. One of the most amazing changes is the development of hair. During the course of the pregnancy, the fetus will develop hair on its head and body. In this article, we will discuss when the fetus will develop hair and what type of hair it will have.
When Will the Fetus Develop Hair?
The fetus will begin to develop hair at around 21 weeks into the pregnancy, or 19 weeks after conception. At this stage, the baby will be completely covered with a fine, downy hair called lanugo. The lanugo helps hold the vernix caseosa on the skin, which is a white, waxy substance that helps protect the baby’s skin from the amniotic fluid.
The lanugo will start to shed off around 32 weeks into the pregnancy, or 30 weeks after conception. After the lanugo is shed, the baby’s head will be covered with a thicker, darker hair called the vellus hair. This hair will continue to grow until the baby is born.
In conclusion, the fetus will begin to develop hair at around 21 weeks into the pregnancy, or 19 weeks after conception. This hair is called lanugo and it helps protect the baby’s skin from the amniotic fluid. The lanugo will start to shed off around 32 weeks into the pregnancy, or 30 weeks after conception. After the lanugo is shed, the baby’s head will be covered with a thicker, darker hair called the vellus hair.
