Why do you want to cut the full moon head?

The popular saying is: shaving a "full moon head" at the full moon means that everything starts from scratch, and the more the fetal hair is shaved, the denser it is. There is rhetoric in meaning, but it is unscientific to shave it tightly.

In this regard, Zou Xiaoyan, director of the dermatology department of Hubei Maternal and Child Health Hospital, said that it is wrong to say that fetal hair is thicker and denser, which is a kind of "superstition". Because hair thinning or thickening is related to hair follicles and pores on the scalp, the growth speed, thickness and thinning degree of baby's hair are affected by many factors, such as parents' genetic factors, baby's nutritional status and growth and development level. In most cases, parents' hair is thicker, and the baby's hair will be thicker after birth.

According to reports, under normal circumstances, when full-term newborns are born, scalp pores and hair follicles are mature and the number is relatively constant. Hair grows about 0.3 mm every day for about 3 days1mm. The amount of vitamins, the length of sunlight exposure and so on have certain effects on the growth rate of hair. Shaving fetal hair will only shorten the original hair, not increase hair follicles and pores, and of course it will not make the hair more and more dense.

The risk of premature shaving of fetal hair is high.

1, the baby's scalp is delicate. If you don't cooperate, in the process of shaving fetal hair, the baby's scalp may be damaged because of twisting the head or the unskilled barber, which will seriously cause bleeding and scalp defect.

2. The blood supply of infected scalp is very rich. Once the baby's scalp is accidentally damaged or even caused local damage, bacteria can easily invade the baby's body through the damaged part, causing local or even systemic infection; If you use shaving tools that are not strictly disinfected, even if there is no obvious scalp defect, there may be some minor injuries, leading to some infectious diseases;

3, damage to the hair follicle baby scalp skin is more delicate, if you do not shave the fetal hair carefully or the hair is shaved too short, it may hurt the hair follicle under the scalp, leading to hair follicle damage, resulting in less hair than before.
