Go hair! 2026

Marina has just been born. Her parents look at her enthralled. “How pretty,” her mother exclaims, “Look, she has blue eyes,” her father says. But the girl's feature that most catches his attention is her rebellious and abundant black hair.

In the next room, Lucas and Paula relax on their mother's chest. They are more than three weeks ahead of their expected birth date, which is why they are two small children, although in their three days of life they have made so much progress that their parents are proud of their strength. Neither Lucas nor Paula have a single hair on their pretty little heads. They are two hairless children.

Juan is about to abandon motherhood in the arms of his mother. Their mother's parents have come to pick them up, solicitous. “He looks like you,” says the grandmother, excited, to her husband. Juan's head is full of snails. “Less about the hair,” responds the balding grandfather.

Abundant or scarce; long or short, the hair of babies at birth is always fine and in most cases dark. If they have been premature, it is most likely that it does not exist. It does not matter: that first hair, if there is any, will fall out in the coming months and will be replaced by another thicker and stronger one.

Sometimes the loss is gradual, little by little the hair is replaced by the permanent one; other times it is rapid and the baby is left with large bare areas, almost always on the back of the head, due to friction with the crib, now that he spends so many hours sleeping on his back.

And what will the new hair be like? Will Marina have untamable black hair? Will Lucas and Paula have rather thin hair? Does Juan have afro curls? To find a clue, you don't have to look at the hair that these children brought into the world, but rather at that of their parents and grandparents. Because hair characteristics are written in the genes: Blonde? Dark? Smooth? Curly? Abundant or scarce?

When one of the parents has black or brown hair, it is likely that the child will also have it because the gene for dark hair predominates over that for light hair, just as the gene for curly hair predominates over straight hair. But sometimes genetics surprises. It's that capricious. By a year or a year and a half, new hair will have grown, but it will not yet cover the entire head. Then the mystery will be cleared up. When the child sticks two candles, he will show off his final, thicker hair, which, of course, may change color slightly over the years.
