There is no clear requirement on whether the fetal hair of a newborn baby needs to be shaved or not, it needs to be judged according to the season and its own development. 1. Season: If the fetus is born in the hot summer, the fetal hair can be shaved, so as not to cause overheating fetal discomfort; if the fetus is born in the winter, the general fetal hair does not affect the situation, can not be shaved. 2. Their own development: the fetus after birth if it is due to fetal hair is relatively more, a greater impact on the life, can be shaved in the full moon; if the fetus fetal hair growth is less, usually do not need to shave, and can play a certain role in the protection of fetal hair follicle growth. Therefore, whether the newborn needs to shave the fetal hair need to be judged according to the actual situation, regardless of shaving fetal hair, for the baby’s health does not have any effect.
