Some babies are born with a lot of hair, and others come into the world with a completely smooth skull. This is a phenomenon that worries parents who are wondering when their baby's hair will finally appear. The color of the hair will also become a big debate in the family, since everyone will want to know what beautiful hair this baby has inherited.
Some babies are born with a lot of hair on the skull. However, that does not mean they will keep them for the next few months. With the effect of hormones, but also because of recurrent long recumbent positions in newborns, the hair falls during their first months of life. It is therefore important to know this so as not to have false hopes, but also to understand that nothing is definitive in babies.
The same goes for the color that can also change over the months. Your baby can come into the world with lots of black hair and finally become blond later.
Of course, and like all the physical characteristics of your child, genes play an important role. While it's hard to predict the future color of your baby's hair in advance, you can still get closer to the truth by watching yourself. If you both have the same hair color, then there is a good chance your baby will inherit it. If, on the contrary, your hair colors are very different, then it may have a hue between the two. Of course, these words are to be taken with much hindsight, because genetics is an extremely complex science, so it is difficult to predict exactly.
No need to rush on your child from birth to see the color of her hair, since it can still change at all. During the first six months of your child, he will still have on his skull his first hair that will eventually fall to make room for new hair, which will already give an impression of his future color. Anyway, no need to shout victory too quickly, since the final hair color is only visible from 18 years.
Even after this, it is not uncommon to see hair continue to darken, especially because the presence of eumelanin (type of melanin brown to black) continues to increase with age.
The color of a human hair is determined by the type and concentration of a pigment called melanin. There are several types of melanin in hair. The concentration of one of the types of melanin, called eumelanin, gives the hair a black or brown color, and if this concentration is very low, the blond color. The concentration of another pigment, called pheomelanin, gives the red color.
The type and amount of melanin in hair is determined by many genes. The most studied gene that determines hair color in humans is called "MC1R". This gene provides instructions for the manufacture of a protein called "melanocortin receptor type 1", which is involved in the creation of melanin. This receptor controls the type of melanin produced by the melanocytes. When this receptor is activated, it triggers a series of chemical reactions within the melanocytes that stimulate the production of eumelanin.
If this receptor is not functional, the melanocytes produce pheomelanin instead of eumelanin. Many other genes also help regulate this process.
Most humans have two functional copies of the MC1R gene, inherited from each of their parents. These people have black or brown hair, due to the large amount of eumelanin present in the hair. It is estimated that more than 90 percent of human have brown or black hair!
Some people have variations of a copy of the MC1R gene in each cell who deactivates the gene. For these people, the production of eumelanin is lower, while the production of pheomelanin is higher, which gives them a light brown, blond or red color.
The color of the hair can change over time. And especially for people from European origin. For example, children with blond hair often have darker hair when they become teenagers. The researchers speculate that some hair pigment proteins are activated as children grow older. With age, our hair turns gray when the hair follicle loses its ability to produce melanin.
Did you know that redheads represent only 1 to 2% of the world's population? So if this is your natural color, rejoice! Many blond, chestnut and brown women who want to go red through a permanent color. If this atypical color was subject to some mockery in the playground, it now takes a nice revenge, especially with celebrities.
In addition, the red keeps its pigments longer and delays the appearance of white hair.
Make no mistake, rare are naturally blonde women (1 in 20 women!). And for good reason, the blond is linked to recessive genes. That is to say, it takes two determining this character, one from the father, the other from the mother.
If this color fascinates so much, it is because it would be a sign of youth, sweetness, but also of seduction. Men do not they have a penchant for blondes?
Lighter than red, but brighter than blond, this original shade has been a great success for centuries. Already in the Renaissance, women thinned their hair with saffron and lemon to get that almost red color. Today, this color pleases women for its delicacy, warmth and good-looking effect!
The dominant hair color is black, sometimes tinged with a brown sheen. This color is mainly prevalent in Africa, West Asia and the mixed populations of South America. The black color is also found in Asia, China, India, and Japan and among the Amerindian populations.
The Mediterranean populations are more brown in color, and black is very present. As one goes back to Europe and Central Asia, the hair becomes lighter: chestnut, red and blond appear. The hues are becoming lighter going back to Russia, Scandinavia and the Baltic states, with blond being the dominant color among them.
This distribution does not take into account population movements and migration, which brought these different colors around the world.
