There is no such thing as how many months is the best time to shave a baby’s lanugo, and it is generally not recommended to shave lanugo without special circumstances, but when the baby’s hair is long and affects the metabolism of his scalp, it can be determined on an individual basis. Baby’s fetal hair has a certain protective effect, if necessary, according to the thickness of the fetal hair and the temperature of the surrounding environment to decide whether to shave. If the baby is born with thicker and denser hair and the child sweats more in summer, it is easy to have prickly heat, then it is appropriate to shave off the hair at this time. If the baby was born after the fetal hair is relatively sparse or in the cold winter premature shaving will lead to baby cold, so you can choose to 100 days or not to shave the child’s fetal hair. In daily life, the tools used to shave the baby’s unborn hair must be clean, and a separate set of barber’s tools should be prepared for the baby to avoid skin damage during barbering. If there is any discomfort, consult a doctor in time.
