I believe that for new parents who have just had a baby, the amount of baby's hair must be uncertain. In fact, when most babies are born, their hair is yellow and little, so what's the reason for the lack of hair in newborns? Let's learn more about it with the editor~
Causes of hair sparseness in newborn
Generally speaking, it is not necessary to worry too much about the thin yellow hair of the newborn. When different babies are born, the density and color of the hair will vary greatly. This is mainly because:
1. Shedding degree of fetal hair
When the fetus develops to 5-6 months in the uterus, the fetal hair will slowly fall off. If there is less shedding of fetal hair, the hair will be thicker at birth; if there is more shedding of fetal hair, the hair volume will be less.
2. Heredity
The hair quality and quantity of a baby are greatly influenced by genetic factors. If the parents' hair grows sparse and yellow, the possibility of the baby growing thick hair is relatively small.
3. Nutrition during pregnancy
The baby's hair is also related to the adequacy of protein and vitamin intake during pregnancy.
Hair tells you that your baby is not healthy
The color and density of hair, to a large extent, come from heredity, but if the baby's hair quality meets the following conditions, parents should pay attention to it.
1. Too yellow or mixed with white hair
This may be due to the lack of some trace elements in the baby, thus affecting melanin metabolism. But parents don't have to worry too much. As the baby grows older and more nutritious, yellow or white hair will gradually fall off and be replaced by black hair.
Suggestion: after the baby starts to eat complementary food, he can eat more foods rich in calcium, zinc, iron, selenium, iodine and other trace elements, such as walnuts, dates, raisins and so on.
2. Sparse asymmetry
Rickets, lack and excess of some elements, genetic metabolic diseases and other children will show sparse hair. If one side is thin and the other side is dense and the two sides are asymmetric, it may be caused by the different development maturity of hair follicles at different positions, or it may be related to the baby's love of side sleeping and sweat secretion.
Suggestion: can help the baby often change sleeping position, wipe the sweat on the head. This will improve as the follicles mature.
3. Alopecia occipitalis
The hair on the back of the head of most newborn babies is very sparse, commonly known as' pillow baldness'. But occipital alopecia is not equal to calcium deficiency. Because the newborn has not yet learned to sit, most of the time every day in the state of lying flat, coupled with the baby sweat secretion is strong, sweat blocking hair follicles may affect the growth of hair, resulting in the phenomenon of pillow baldness. When the baby learns to sit and stand, the hair on the back of the head will gradually grow out. If the baby has alopecia occipitalis accompanied by restlessness, sweating, crying at night, and even valgus and other symptoms, it is the performance of calcium deficiency.
Suggestion: if there is a small swelling papule at the root of the hair follicle of the baby's scalp, it is a little hard and prickly to feel. It may be keratotic papule of the hair follicle. In this case, when the baby is one or two years old, there will be no hair in a certain area. Parents had better take their baby to the hospital for examination, and supplement the baby with vitamin D and calcium under the guidance of the doctor.
4. Long hair
Malnutrition, anemia, weakness of spleen and stomach, lack of calcium, zinc and other reasons will cause the baby's hair to grow vertically.
How to change baby into 'black thick straight'
1. Don't shave your head
There is a popular saying that "shaving your baby's head will make your hair darker and denser". In fact, there is no scientific basis for this. Shaving your head will not only damage your baby's hair follicles and prevent the growth of your hair, but also may cause infection. Especially in summer, your baby likes sweating, and shaving is more likely to damage your baby's immature scalp. It is suggested that parents should not shave their babies too short. Sweaty babies should wash their hair frequently to keep their scalp clean.
2. No random calcium supplement
In the absence of medical indications, vitamin A and calcium zinc gluconate oral solution are not recommended for long-term use. If any abnormality is found, you can go to the hospital for relevant examination to find out the exact reason.
3. Nutrition assurance
The mother can strengthen nutrition, ensure the quality of breast milk, let the baby get balanced nutrition, the symptoms will gradually improve. The main body of hair is protein, to ensure that the baby's adequate protein intake, can appropriately eat meat, eggs, milk, fish and other food.
