Pregnancy is an exciting time filled with many milestones. One of the most anticipated moments is when a baby starts to develop hair. Many mothers-to-be wonder when this will happen and what it means for their baby’s development. In this article, we will explore when a baby develops hair during pregnancy and what factors can affect this process.

When Does Hair Begin to Develop?

Hair development in a fetus typically begins around the 14th week of pregnancy. While hair follicles start to form around week 9, it is not until week 14 or 15 that the hair fibers themselves start to grow. At this point, the hair is very fine and delicate and is often called “vellus” hair. This hair covers the entire body, including the face, and serves to protect the skin and regulate the temperature of the developing fetus.

When Does Hair Become Visible?

The vellus hair that covers the fetus will eventually be replaced by coarser, more pigmented hair. This typically occurs around the 20th week of pregnancy, though it can vary from baby to baby. Some babies may be born with a full head of hair, while others may not have much hair until months after birth. Genetics play a role in determining how much hair a baby will have and when it will become visible.

What Factors Can Affect Hair Development?

While hair development is a natural process, certain factors can affect it. Here are some things to keep in mind:

  • Genetics: As mentioned, genetics plays a major role in determining when and how much hair a baby will have.
  • Nutrition: A balanced diet that includes plenty of vitamins and nutrients is important for fetal development, including hair growth.
  • Hormones: Hormonal changes during pregnancy can affect hair growth, and some women may experience changes in the texture or thickness of their own hair.
  • Stress: High levels of stress can affect fetal development in a number of ways, including hair growth.
  • Medical conditions: Certain medical conditions or medications can affect hair growth in a developing fetus.

Should You Worry if Your Baby Has Little or No Hair?

It is completely normal for babies to be born with little or no hair. As we mentioned earlier, genetics plays a big role in determining when and how much hair a baby will have. Just like with adults, hair growth can vary from person to person, and some babies may simply take longer to develop hair than others. If you are concerned about your baby’s hair growth, speak with your pediatrician, who can help determine if there are any underlying issues that need to be addressed.

The Bottom Line

Hair development is an exciting part of pregnancy, but it can also be a source of stress for some moms-to-be. Remember that hair growth is a natural process that is influenced by genetics, nutrition, hormones, stress, and medical conditions. If you have concerns about your baby’s hair growth, talk to your doctor. Otherwise, sit back, relax, and enjoy the many milestones that come with bringing a new life into the world!
