《外台》∶崔氏初剃儿头良日∶寅、丑日吉，丁、未日凶。
《集验方》∶京畿初剃头不择日，皆于盈月日剃之。盖风俗所尚。前此产妇未得出房，盈月即与儿俱出，以

头上捺之，以避风邪。其后小儿剃头，亦宜用此。

《外台秘要》记载：崔氏关于婴儿初次剃头的吉日选择：寅日和丑日为吉，丁日和未日为凶。
《集验方》记载：京城地区初次剃头不择选日子，都在婴儿满月之日进行。这大概是当地风俗崇尚所致。在此之前，产妇尚未出房，满月时便与婴儿一同出来，认为胎发污秽不洁，容易触犯神灶，导致小儿不安，因此这一天必须剃头并让母子出门。剃头应在温暖且避风的地方进行。剃完后，需用生油、杏仁和腻粉涂抹在头上，以抵御风邪。此后小儿再次剃头，也适宜使用这种方法。

According to the *Waitai Mi Yao* (Essential Prescriptions Worth a Thousand Gold for Emergencies): Cui Shi's auspicious days for an infant's first haircut: The Yin and Chou days are auspicious, while the Ding and Wei days are inauspicious.
According to the *Ji Yan Fang* (Collected Proven Prescriptions): In the capital region, no specific day is selected for the first haircut; it is always performed on the day of the full month (one month after birth). This is likely due to local customs. Prior to this, the mother had not yet left her confinement room; upon reaching the full month, she would leave together with the infant. It was believed that lanugo (fetal hair) was impure and could offend the deity of the stove, causing the infant to be uneasy. Therefore, on this day, the head must be shaved before going out. The haircut should be performed in a warm place sheltered from the wind. After shaving, raw oil, apricot kernels, and calomel should be applied to the head to ward off wind-pathogens. This method is also suitable for subsequent haircuts of the infant.
According to the *Waitai Mi Yao*: Cui Shi's methods of propitiation and expiation (rituals to avert disaster):
