What Causes A Baby To Have Straight Or Curly Hair?

Many babies are born with straight, curly hair, while others on both sides of the family are born with kinky, rough hair. The cause is amniotic fluid, which keeps baby hair soft and fluffy while still in the womb.

Curls present at birth usually grow out and remain that way after birth for babies. The baby’s hair may start straight but turn curly or even kinky if the parents’ genes contain a mix of hair textures.

  2. Pheomelanin, which results in hair that is red or yellow.

6 Proven Signs Your Baby Will Have Curly Hair

Sign 1: Genetic influence 

Babies are the genetic mixture of their parents. A website named “Healthline” states the Genetic material that moms and dads provide to their children. Identifies whether or not their babies will have curly hair from birth. 

You can call it a “gene game.” Because if one of your genes competes for a dominant position in deciding hair texture. In other words, the hair will have some curl if the curly hair gene is present anywhere in the DNA combination.

  • If both mom and dad have curly hair, then the baby will very likely too!
  • Suppose one parent has curly hair while the other has straight hair. In that case, the gene for curly hair will probably predominate over the other gene, which means that the baby’s hair will either grow curly or wavy.
  • In most cases, the father’s gene predominates over the mother’s genes.
  • If the grandparents had curly hair and those genes are present in the mother’s or father’s DNA, the likelihood of babies having curly hair remains high.
  • Even if neither parent has curly hair, your child may inherit this trait if anyone else in the family does.

Remember, we are not here to predict which genes your child will inherit. These are our assumptions about your baby’s genetic makeup.

Sign 2: Having Acid Reflux While Pregnant

There is a famous saying “If you had any degree of acid reflux or heartburn while pregnant, your baby would come with a complete head of hair.”

Later, a study from John Hopkins University found that the child had a lot of hair on the head in 82% of the pregnant women who experienced heartburn. In contrast, the kids of those who didn’t have hair.

Further research discovered that the hormone that opens the esophagus and permits acid to flow upwards is also responsible for babies’ hair growth. Furthermore, the same hormone may be involved.

So, kudos to those acidic moments during pregnancy. Your baby might end up with curly hair! Make sure to be careful of heartburn if your wife is pregnant

Sign 3: Frizzy Hair Can Lead To Curls
