Newborn baby's back hair

When a child is just born, parents usually conduct a comprehensive examination of the child to ensure that there is no abnormality in the child's health. Newborns do not have much body hair other than their hair. However, some newborns have hair on their backs. This abnormality in the child will definitely make parents very worried, and the key is to know the reason. So, what is the reason for the hair on the back of a newborn baby?

This is mainly because there is no medulla in the middle and the color is very light, almost without pigment. The lanugo will turn into velvet hair at birth. Soft hair is also soft, with no medulla in the middle. The difference from the lanugo is that the color is a little darker than the lanugo. The length of velvet hair generally rarely exceeds 2 cm. For example, the fine hair on women's face or arms is velvet hair. Generally, the lanugo on the head will fall off once when the baby is seven to eight months old in the womb, and the second time will fall off quietly not long after birth. Therefore, except for special diseases or premature babies, lanugo can generally only be seen on the body and face (such as the forehead) of a few newborns, and the hair on the head will quickly change from lanugo to slightly colored velvet hair after birth.

Newborns generally have varying degrees of lanugo. After birth, the baby's back, forehead, and ears will be covered with dense black hair. This can be used to determine whether the newborn has a lot of lanugo. Children with this much body hair will generally fall off on their own. Pay attention to check their blood and urine to see if there are any abnormal liver and kidney functions, abnormal sleep, bowel movements, physiological jaundice, or problems caused by abnormal pituitary development.
