When Do Babies Grow Hair in the Womb?

Sometimes, a baby can have full hair when he or she is born. You can see a baby born bald as well. Both scenarios are normal. 

However, what we shall try and answer the question, “when do babies start to grow hair in the womb?”

We know you are reading this article now to know if babies grow hair in the womb and the time it happens. We will give you all the information you need.

Fetal Hair Growth and Development

Around the period 14 or 15 weeks into your pregnancy, your baby tiny hair begin to poke through their skin slightly.

When the baby gets to this period, the baby is about to get their hairline soonest. 

Baby hair growth on the womb happens in two steps — the shedding stage and the regrowth stage.

All hair follicles are formed before the birth of the baby. Around the time your pregnancy is in week 22, the baby eyelashes and eyebrows would start to emerge.

The baby’s hair growth not restricted to their head alone. By week 14, the baby is covered entirely by a soft material called lanugo. 

The purpose of the lanugo is to keep the baby warm. However, as the baby grows more body fat, the lanugo begins to shed because the body fat will take over the job of keeping the baby warm.

Hair Color and Volume

Hair generally is pigment(color) free during pregnancy. All babies irrespective of their ethnicity have the same thin and slick hair at birth. 

As the baby grows, he or she would shed more hair before they get their final hair color. Usually, it takes about two years for the process to be complete.

Often, mothers wonder the type of hair and complexions of the hair they would have. 

But it is a bit predictable. Baby’s with darker complexions have slower hair growth and shedding cycles. With these slower-growth, these babies have a thicker head of hair.
