The sex of a child can be determined long before it is born, but the physical features remain unknown until birth. Who will he look more like – dad or mom? One of the most discussed elements of appearance is the baby’s hair. Color is what they first pay attention to determine the similarity to one of the parents.
Not all parents know that the hairline is very changeable. This is typical for young children and less often for teenagers. Changes in hair color can occur during the natural development of the body in infancy. It all depends on heredity.
Probability of Baby Born with Blonde Hair
Genetics is a very complex science, but it will be enough to touch upon only the basic laws. The probability that a baby will be born with blonde hair is over 95% if both parents are natural blondes. This is due to the dominance of the corresponding genes.
The dominant trait is inherent in women most often. If the mother is blonde and the father is brunette or red, then the probability of blond offspring is above 50%.
What is the probability of having blonde children with a blonde dad? The probability is less than 50% when conceiving a child with a fair-haired woman or a brunette. Usually blonde children are born in a family where the dad is blonde and the mom is fiery red. If both parents are carriers of recessive genes, then the dominant genes of their parents may come to the fore. Sometimes children look a lot like their grandparents for this reason.
Will Hair Change Color in Time?
The first human hair can form in the womb. They grow there and may fall out partially or completely. This is why some babies are born with noticeable hair on their heads, while others are bald. Only a small fluff remains from the original hairline. Its color can have very unexpected shade.
The color of a person’s hair practically cannot be the same throughout life. Only absolutely red hair color does not change. It can only slightly darken or brighten. Color change may occur a couple of months after birth. You can observe more than once such natural “image changes” in the first two years.
Even when a child reaches the age of two, it is impossible to say with certainty, their hair has acquired the final stage color. The color can change significantly in 4-5 years from a light to a darker shade. This is due to the accumulation in the body of a special pigment – melanin. Hair often darkens during adolescence. This is one of the signs of puberty in the body.
Why Some Babies are Born with Blond Hair?
Not all newborns have hair on their heads. The first hair fell out in the womb if the baby was born bald. New hair will begin to appear and this may take about a year.
Natural blondes are only 2%, but people with blond hair are born much more often. This is due primarily to the lack of melanin in a young body. This pigment accumulates over the years and as it accumulates, a change in the color of the hair and skin occurs.
Hair color is mainly influenced by genetics. The baby does not always adopt the features of appearance from one of the parents. Other factors begin to influence the formation of hair color if the father and mother are both carriers of a recessive or dominant gene. Genes from previous generations can determine the thickness, length, and shape of a child’s hair.
Chances of Baby Being Born with White Hair
Sometimes a small strand of white hair is noticeable on the baby’s head immediately after birth. There is no way to eliminate this distinctive feature. All hair on the head will eventually be renewed, change color, but gray hair will remain.
A congenital tuft of white hair in a newborn is designated by a special term in medicine – premature graying. It does not pose a real threat to the health of the child, except in very rare cases.
The newborn is immediately examined by doctors to make sure that there are no health risks when white hair is detected. More concern for parents should be the appearance of white hair in a growing baby. This fact may indicate a lack of vitamin B12 in a child. It is worth consulting a doctor in this case.
Having a Baby with Albinism
Sometimes babies are born with translucent white hair. The same color is typical for eyebrows and eyelashes. This phenomenon is known as albinism – the pigment melanin is absent in the body. Lack of pigmentation shows up in skin tone and eyes.
Albinism is often inherited. An albino person will likely have a relative with the same disease in the next generation. Children without pigmentation are born to a couple with no albino relatives in previous generations. This can happen if both parents are carriers of abnormal genes.
Albinism is an incurable disease. A person will remain for life with transparent white hair all over his body. Albino children are born about once in 20,000 people. They should not have problems with adaptation in a civilized society.
Is it Something to Worry about?
If a fair-haired child is born in a married couple of brunettes, this may serve as an occasion for a showdown. Do not immediately accuse your spouse of treason. Many babies are born with blonde hair. The color will change and the child will become more like parents with age.
Parents often panic after the birth of an albino child. In this case, you should not worry about the lack of pigmentation. Albinos are endowed with full physical health. Problems arise only with vision and tolerance to sunlight. It is worth consulting with a doctor and following his recommendations in the future on this issue.
Young mothers take care of their children so closely that any physiological changes are mistaken for a deterioration in health. Hair loss in babies is instantly associated with a lack of vitamins or some kind of disease. Everything can be much simpler.
A baby may lose hair if born with relatively thick hair within a few months. Baldness can be partial or complete. Hair falls out on the back of the head and in the temple area most often. There are two reasons. Mechanical: the baby most often rubs the back of the head and temples on the bed. Hair falls out from friction because it has not yet had time to take root. Physiological: there is a change in the hormonal background.
