Hair On Ultrasound Vs When Born: What You Need To Know


When it comes to prenatal ultrasounds, many parents are eager to see what their baby looks like before they are born. One aspect that some may be curious about is whether or not their baby has hair on the ultrasound. In this article, we will explore what ultrasound images can tell us about fetal hair growth, and how it may differ from what you see when your baby is born.

What Ultrasound Images Can Tell Us

Ultrasound images can give us a lot of information about a developing fetus, including their size, position, and general health. In some cases, it may also be possible to see details such as the baby’s hair, although this can vary depending on the age of the fetus and the quality of the ultrasound image.

Ultrasound Images in Early Pregnancy

In the early stages of pregnancy, it is unlikely that an ultrasound will reveal any hair on the fetus. This is because hair typically starts to grow on the baby’s head around the 14th week of pregnancy, which is after most early ultrasounds are performed.

Ultrasound Images in Late Pregnancy

As the pregnancy progresses, it may become easier to see hair on the ultrasound image. However, this still depends on a number of factors, such as the position of the baby and the amount of amniotic fluid in the uterus. In some cases, the hair may be visible as a fuzzy outline around the baby’s head, while in others it may be difficult to see at all.

What You Can Expect When Your Baby Is Born

Once your baby is born, you may be surprised to find that their hair looks different than what you saw on the ultrasound. This is because fetal hair is typically finer and less pigmented than the hair that grows after birth. Additionally, some babies may lose some or all of their hair in the first few months of life, only to have it grow back later on.

When Will Your Baby’s Hair Grow In?

The timing of when your baby’s hair grows in can vary, but it is typically within the first few months of life. Some babies are born with a full head of hair, while others may take longer to grow hair. It is also worth noting that the texture and color of your baby’s hair may change as they grow older.

How to Care for Your Baby’s Hair

Once your baby’s hair starts to grow, you may be wondering how to care for it. Here are some tips:

1. Be Gentle

When washing your baby’s hair, be gentle and avoid pulling or tugging on it. Use a mild baby shampoo and warm water, and rinse thoroughly.

2. Brush Carefully

Use a soft-bristled brush to gently comb through your baby’s hair, being careful not to irritate their scalp. You may also want to use a detangling spray to make brushing easier.

3. Avoid Heat Styling

Avoid using heat styling tools such as blow dryers or straighteners on your baby’s hair, as this can damage delicate strands. Instead, let their hair air dry naturally.


While it may be exciting to see your baby’s hair on an ultrasound image, it is important to remember that this may not be a completely accurate representation of what their hair will look like when they are born. However, once your baby arrives, you can look forward to watching their hair grow and caring for it as it changes over time.
