Patient's question:
My baby has a patch of hair that is particularly thin on top of her head, with white scalp underneath. It wasn't like this in the first three months, and when I cut her hair, it was all the same color. But after I gave her a haircut at four and a half months, I noticed a patch of hair that was very light in color. Since then, that patch hasn't grown much hair. Some people say it's because she's rubbing it, but I don't know why.Doctor's answer:
It's just that the rubbing causes the child's head to turn back and forth while sleeping, which makes it easy to rub off the hair. As the child grows older, these phenomena will naturally disappear. It could also be due to dietary reasons, such as insufficient nutrition leading to thinning hair. One solution is to increase nutrition, maintain a balanced diet, and feed the child reasonably. Additionally, supplementing with some vitamin D and calcium can help. Also, ensuring the child gets enough sleep and sunlight is important, as sunlight can also promote calcium absorption, which can prevent hair thinning caused by calcium deficiency.
