Why do children's hair grow fast?

Many people have found that their children's hair grows very fast. Some people say that this phenomenon is abnormal, so many parents are very worried about it. In fact, this is a normal physiological phenomenon and there is no need to worry about it. Today I will explain to you why children’s hair grows so fast. I hope it will be helpful to you.

The development stage of a newborn's hair goes through lanugo, soft hair, and finally turns into permanent hair, with the time varying. Generally speaking, the fetus will grow lanugo when it is 4 months old in the mother's body. After full-term birth, every newborn experiences at least one (back of the head) and two (central) hair shedding episodes, followed by new hair growth. After half a year, the hair growth enters another stage. The hair will be reborn and permanent hair will grow, starting a stable hair growth cycle. For some babies, their lanugo will slowly fall off while in the mother's womb; if the lanugo falls off less, the baby will have more hair when he is born.

A baby's hair growth usually starts from the forehead and the top of the skull. The hair grows at different rates in different areas, so it often looks sparse. It is widely believed in folk custom that shaving off a baby's hair and eyebrows when the baby is one month old will stimulate the hair follicles and cause them to grow thicker and denser. In fact, this concept is not quite correct. 2 or 3 months after birth, hair growth is still in a slow stage, so parents don't need to be too nervous. Usually, hair will begin to grow gradually about half a year after birth. If there is no sign of hair growth after more than a year, you need to consult a doctor.

Hair color depth

The shade of hair is closely related to genetic inheritance. For Orientals, the hair color is black. After a baby is born, the permanent hair has entered the stage, so the hair color should be black. But there are a few babies whose hair is dark brown or lighter brown-black, which is mostly normal. If some hair appears gray, it may be because some hair follicles are in the aging stage, which is not a big deal. However, if a certain area of ​​hair appears to be mostly white, it may be due to illness.
