When Do Babies Hair Change Color (Explained)

Many new parents seem to worry quite a lot about the phenotypic makeup of their babies. You know, the visible characteristics like eye color, complexion, body type, and hair color.

Hair color is one factor that new parents, mothers especially, worry about so much. Some babies could be born with red hair, but as time goes on, their hair color changes to a shade of brown.

This phenomenon is quite common. That is why we’ll dedicate this article to answering the popular question. When do babies hair change color? We’re pretty sure you want to know why too. So, read on and find out why!

When Is The Hair Color of Babies Determined?

Before we answer the question when do babies hair color change, we will first take you through the hair formation process of babies and when their hair colors are determined. Knowing these things will help you understand every other thing better.

Remember in your high school biology class when the teacher said humans are made up of 46 chromosomes? It would interest you that the 46 chromosomes that constitute your genetic makeup are not obtained from one parent alone.

A baby comprises forty-six chromosomes, twenty-three from the mother and twenty-three from the father.

That sums up to forty-six, right? Perfect! That’s how it goes. If you’re curious about what chromosomes are, I’ll tell you.

Chromosomes are the units of inheritance found in the genes. They vary from individual to individual. No two people can have the same type of chromosomes. They can only have similar ones.

Sometimes, you’d see a baby and say the baby looks a lot like its mother. You’d see the father and say the baby looks like its father.

It’s the work of the chromosomes. Babies are made up of the genes of both parents in equal proportions.

Some traits from one parent way overshadow the other. That is where dominance comes to play. The trait that is greatly expressed is the dominant one, while the one that is overshadowed is called the recessive one.

Now, let us critically look at this baby’s hair color. For example, a mother has jet-black hair. The father has brown hair. From this combination, a lot of things can happen.

The child can inherit the black hair of its mother; it could also inherit the brown hair of its father. The child could even inherit both. You know, a mixture of black and brown.

In some cases, the child might have a different hair color entirely. Genetics and inheritance run deep.

So, when you worry about your baby’s hair color, you should keep in mind that genetics is a very broad thing and that your expectations won’t be met all the time.

You should also note that the baby’s hair color is determined in the womb. Yes, even before the baby is born, it has a set hair color. If your baby has brown hair, it was determined in the womb already.

We know this might confuse you, so we’ll break it down. The whole chromosome thing happens in the womb.

Could My Child’s Hair Color Change?

The answer is yes! Since the amount and nature of pigment are already embedded into your child’s DNA, it’s still developing. This can go on until they are 6-7 years old.

A child’s hair color can significantly change over several years. Due to the pigment, its density and distribution are still adjusting and “settling” in.

One scientific research revealed that people of European descent are usually prone to hair color change.

Scientists are still unsure why this is so and how. But many believe it results from hormonal changes, activating the melanin in the hair follicles.

A typical study found that most kids with blond hair grew up to have darker locks when they hit their teenage years or puberty.

Certain conditions, caused by what medical experts call loss of function, that cause variation in color.

1. Poliosis

Poliosis is, also known as “white forelock” is a condition where a particular spot of hair is white.

Looking closer at this phenomenon, medical experts concluded that the hair follicles in that spot lack melanin.

While the rest of the hair, however, is a natural color, either brown or black. This makes for a very particular appearance.

As you may know, poliosis occurs when several genetic syndromes occur simultaneously. These syndromes include tuberous sclerosis, piebaldism, and Waardenburg syndrome.

Medical experts have concluded that it can occur due to a series of acquired conditions.

These conditions include inflammatory illnesses, medications, or benign skin tumors.

In some babies, poliosis can also affect other parts of the human body, like eyebrows or eyelashes. Even though this may sound serious, most people with it are perfectly healthy.

2. Albinism

Albinism is generally a genetic condition resulting from the absence of melanin in the hair, skin, and eyes.

People with this condition are often known to have very fair skin and white hair. However, there are so many variations.

Albinism is very common, especially in other countries worldwide. As many as one in 3,000 babies are born with it. This condition affects about one in 15,000 to 20,000 people in the United States.

As you may know, albinism is not a condition your baby can inherit after delivery because it occurs due to a mutation in the genes. The possibility of your baby having it is quite slim.

Typically, for a baby to be born with albinism, both parents must carry the mutated gene. However, research has shown that there is another variation where the mother is the carrier. This type usually only affects the XY chromosome.

Albinism is not malignant, but it can cause poor vision for the person with it. Fortunately, as time goes on, this condition can be corrected.

It is important to note that kids with albinism must always be protected from the sun. This is because their sensitive skin lacks pigmentation and can easily become sunburnt.

It is very important to apply sunscreen creams and dress them in non-transparent clothing, including hats and loose shirts.

It’s not unusual for some parents to be concerned about whether or not they will have a child with albinism. If it worries you, do not hesitate to speak with your doctor.
