Patient's question:
Patient Age: Two years oldA two-year-old child used to have very black hair, but now it is becoming increasingly yellow. What is the reason?
Doctor's answer:
Hello! There are multiple factors or causes for yellow hair, including different races, genetics, and the content of trace elements such as iron, lead, zinc, cobalt, copper, platinum, and nickel in the hair, as well as the amount of melanin in hair cells and certain medical conditions (e.g., phenylketonuria, kidney disease). Therefore, hair turning yellow is related to nutrition and illness. Since medical conditions have been ruled out, excessive consumption of sugar, fat, and acidic substances in the diet can cause hair to turn yellow, as can a lack of certain trace elements (e.g., iron, copper, zinc). A deficiency in copper can reduce the function of tyrosinase, affecting melanin metabolism, while a lack of iron and zinc can impair hair cell development and growth, leading to yellow hair.Advice: It is recommended to get a medical examination. You can have your baby undergo a trace element test. Additionally, you can encourage your child to drink colostrum, such as LifeSun Colostrum, which can improve iron absorption and transport, blood indicators, and gut and respiratory health.
