Pregnancy is a time to eat healthy and nutritious food to ensure proper growth and development of the mind and the body of you and your little bean. Eating right is also essential for the health of the baby and especially for the growth of the hair. Your baby’s hair growth happens in cycles of shedding and regrowing. As a parent, you are probably keen to know everything about your baby’s hair growth during pregnancy.
The development of the baby’s hair depends to a large extent on the mother’s diet. Eating foods that help with good hair growth is important for the baby. The hair of the baby starts growing in the womb around the 14th to 15th week of her pregnancy. The hair follicles start appearing and no further growth takes place after the baby is born. Thus, it is important that the mother eats well so that good hair growth is seen after the baby comes into the world.

Fetal Development of Hair on Your Baby’s Head
Hair on the baby’s head also develops during the fetal stage. What the mother eats plays a major role in the hair formation in the baby. For this reason, mother should eat nutritious food that encourages healthy hair growth in the fetus.
Here is what you should know about the development of baby’s hair.
- The hair follicles form a pattern on the baby’s scalp that stays for life during the fetal stage.
- After birth, no new follicles appear.
- At 22 weeks of pregnancy, the hair can be seen on the head of the baby.
- It can grow in a bunch or very little by the time the baby is born.
- Once the hair starts growing, the melanin-producing cells start functioning, adding colour to the strands.
- Predicting the hair and the hair colour of the baby is not easy.
- Many genetic factors decide the right amount of melanin that goes in every hair strand but there is no evidence for their interaction to produce different hair colours.
- This is the reason why the hair colour and texture stay as a surprise and the baby’s hair can resemble anyone in the family.
- It is not important that the hair of the baby at birth be the same for the rest of their life.
- Babies are seen losing their hair in the initial 6 months and new hair being replaced by it.

Fetal Development of Hair on Your Baby’s Body
Your baby will develop hair not only on their head but also on the rest of their body before entering this world. It is a surprise that most of the development is done before the baby is born. Let us see the process of growth.
- The hair follicles appear deep in the skin of the baby around the 14th to 15th week of pregnancy.
- By 20 weeks, small hair starts sprouting from the follicles on the eyebrows, chin, upper lip.
- This is also the time when hair can be seen on the shoulders, back, ears and forehead and also called lanugo.
- Lanugo holds a greasy substance called vernix, which protects the skin of the baby from consistent exposure to the amniotic fluid.
- This lanugo covers the whole body and most of it is gone before the child is born.
- It is seen that premature babies are born with a lot of hair as they come before time and the hair is not shed by then.
- On the other hand, in full-term babies, this hair is shed off.
- Lanugo starts to fall within the initial weeks of birth but for some babies, it can stay for long as well.
- The colour of the lanugo can be different from the hair on the baby’s head.
- The hair colour is dark and seen better
