The hairs usually fade away about 3 months after birth, but there may be individual differences in how long it takes to fade away. It is normal for newborns to have a lot of hair on their skin, especially if they are born prematurely. In most children, the hairs will gradually fade away after about 3 months of life. However, there is some individual variability and the child needs to be monitored. In general, this will not adversely affect the child’s growth and development. Pay attention to keep the skin clean and take good care of the skin to reduce the irritation of fetal hair and sebum on the skin, which is also conducive to the child’s comfort level and reduce the child’s crying and discomfort. If there is any discomfort, consult a doctor in time.
