Why doesn't a baby grow hair after a shaved head

After shaving babies' hair, their hair never grows out. Many parents find this strange and worry about it. In fact, the development of newborn hair is a fast and slow process, and they will experience 1 to 2 natural shedding processes after birth. After one and a half years old, the hair will basically grow well and have a full head of hair. Whether the hair grows well is actually an expression of whether the nutrition in the later stage is balanced.

1. The development of newborn hair goes through lanugo, soft hair, and finally evolves into permanent hair. This process varies in speed. Generally speaking, the fetus will grow lanugo when it is 4 months old in the mother's body. For some fetuses, the fetal hair will slowly fall off while in the mother's womb; if the fetal hair falls off less, the baby will have more hair when it is born.

2. After birth, new hair grows after 1-2 rounds of natural shedding. The first batch of hair loss usually occurs at 2 to 3 months, starting from the back of the head. After half a year, hair growth enters another stage, with the baby's hair being reborn and growing permanent hair. A stable hair growth cycle begins. A baby's hair growth usually starts from the top of the forehead, and the hair grows at different rates in different areas, so it often looks sparse or mosaic-like. Parents don't need to be too nervous about this. Usually, the hair will begin to grow gradually about half a year after birth, and by about one year old, the growth rate of all the hair will tend to be basically the same. By the age of one and a half, the hair has basically grown out and the head is full of hair.

3. Comprehensive and balanced nutrition is extremely important for baby's hair growth. Therefore, it is necessary to add complementary foods to the baby every month. First of all, you must pay attention to your baby's balanced nutrition, which is extremely important for hair growth. You must ensure the intake and combination of meat, fish, eggs, fruits and vegetables. Iodine-rich seaweed and kelp should also be fed to your baby regularly.

4. If the baby has picky eating habits, partial eating habits and bad eating habits, they should be corrected as soon as possible to ensure that rich and sufficient nutrition is supplied to the hair roots through the blood circulation, promote hair growth, and make the hair grow stronger and more beautiful.
