Question
The newborn has not received any treatment yet, and their hair has become very yellow. Does this mean they are lacking in some vitamin?
Answer
A hair trace element test can be conducted for the baby. If zinc is deficient, supplement with zinc; if iron is deficient, supplement with iron; if copper is deficient, supplement with copper. Hair turning yellow can be caused by various factors, including different ethnicities, hereditary issues across generations, and the content of trace elements such as iron, lead, zinc, strontium, copper, palladium, and nickel in the hair, as well as the amount of melanin in the hair follicles and whether the baby has any diseases (such as phenylketonuria, kidney disease). Therefore, yellow hair may be related to nutritional deficiencies or diseases. If diseases have been ruled out, an excess of sugar, fat, and acidic substances in the diet may also cause hair to turn yellow. A deficiency of certain trace elements (such as iron, copper, and zinc) may also lead to yellow hair. Copper deficiency can lower the function of tyrosinase, thereby disrupting the decomposition metabolism of melanin. Iron and zinc deficiencies can also interfere with the growth and development of hair follicles, leading to yellow hair. It is recommended to have the baby tested at a hospital. You can have your baby undergo a trace element test.
