Reasons why newborns' hair grows slowly

In fact, for newborns, parents need to learn a lot of things in the process of taking care of them, so that once a situation occurs, they can deal with it easily and will not appear to be so flustered. However, it is also possible that the newborn's hair grows slowly. In fact, there is no need to worry about this. It is related to genetics. So let us understand the reasons why newborns' hair grows slowly.

Hair formation

When it comes to hair problems, we must first understand the process of hair formation. Hair is produced by hair follicles, which are important members of skin tissue and are closely related to the formation of the skin. The initial hair follicle matrix appears in the epithelial layer three months into embryonic development. At first, it is only seen on the eyelids, eyebrows, chin, nose, etc., and then gradually appears on the back, abdomen, and limbs. At the same time, it gradually grows into a more mature secondary hair follicle matrix and shows a cyclical growth phenomenon. At this time, the hair follicle cells are buried in the dermis and begin to form soft hair. The sebaceous glands, arrector pili muscles and vascular plexus also attach to form a relatively complete hair structure. Of course, hair begins to appear at this time.

Before the embryo is seven months old, the hair on the entire scalp, except for the back of the head, is in a period of rapid growth, while the hair on the back of the head is in a relatively slow growth state.

Baby's hair growth process

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, the 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.

The above article gives you a detailed introduction to the reasons why newborns’ hair grows slowly. I believe you already have a preliminary understanding of it. So in your daily life, if you encounter such a phenomenon, you should consult a doctor.
