Question
Why did my baby’s hair turn yellow again? Is it malnutrition?
Answer
The baby’s hair turning yellow may be due to zinc deficiency. It is recommended to increase intake of zinc-rich foods and consider taking dextrose glycine zinc for two to three months. Less common genetic metabolic disorders, such as phenylketonuria, can also lead to lightening of skin and hair pigmentation, and diagnosis requires phenylalanine concentration testing and DNA testing.
