Under normal circumstances, fetal hair will fall off by itself. Under normal circumstances, newborns will shed their own hair within 1-5 months after birth, which is a normal physiological phenomenon and will not cause adverse effects on newborns. Parents do not need to be overly nervous, and should clean up the shedding of hairs in time to prevent the shedding of hairs from irritating the newborn’s skin and causing itching or redness. In addition, parents are advised to pay more attention to the newborn’s physical development, if the hairs have not fallen off for a long time or there are abnormalities in the skin or body, they should consult a doctor as soon as possible to clarify the cause and choose the appropriate method of treatment to prevent aggravation of the condition.
