As your little one develops in the womb, fascinating changes occur, particularly in the formation of hair, skin, and nails. This article will delve into when your baby begins to grow these features and what to expect.
Hair Development in Babies
Around the 14th to 15th week of pregnancy, your baby starts to sprout fine hair, known as lanugo, which initially appears at a slight angle from the skin. This early hair growth lays the groundwork for your baby’s future hairline. By approximately week 22, you can also expect to see the development of eyelashes and eyebrows. Interestingly, throughout pregnancy, your baby’s hair undergoes two cycles of shedding and regrowth, resulting in a well-defined pattern of evenly spaced hair follicles.

Skin Formation
Your baby’s skin begins as a transparent layer that evolves over time. The primary layer responsible for skin formation is the ectoderm, which also contributes to hair and nails. As the pregnancy progresses, the skin develops essential features, including vernix caseosa – a protective coating that helps shield the baby’s skin from amniotic fluid.

Nail Development
Fingernails and toenails begin to form around the 20th week of pregnancy, initially appearing as small, soft, and translucent. By the time your baby is born, these nails will have developed more fully, although they may need some time to grow stronger and thicker after birth.
