Babies usually do not need to shave their fetal hair. The custom in many places is that after the baby has been born for some time, the parents will shave the baby’s fetal hair in time. In fact, whether or not to shave the baby’s fetal hair has no effect on the baby’s healthy growth. After the baby is born for a period of time, the fetal hair will automatically fall off, and then new hair will grow back. Whether the newborn hair grows luxuriantly or not depends on how active the hair follicle cells in the baby’s head are and the genetics, which is not directly related to whether or not to shave the fetal hair. Sometimes when shaving the baby’s hair, the baby does not know how to cooperate and improper operation may cause damage to the baby’s head skin and lead to infectious diseases.
