Patient's question:
，normal. What aspects should be noted? Are there any other diseases? First follow-up question: Thank you, expert guanyouyun, I would like to trouble you again, which specific vitamin would be better to supplement? Besides walnuts, what other types of "nucleus" foods are there? Thank you very much!Doctor's answer:
Why do hair turn yellow? The main causes include hypothyroidism, severe malnutrition, severe iron deficiency anemia, and recovery from serious illness, which lead to a decrease in melanin in the body and a lack of the basic substance for black hair, gradually turning black hair into yellowish or light yellow. Additionally, frequent hair dyeing or washing hair with laundry detergent and alkaline water can also cause hair damage and yellowing.Nutritional yellowing is mainly caused by severe malnutrition. Eggs, lean meat, soybeans, peanuts, walnuts, and black sesame seeds contain large amounts of animal and plant proteins, which can improve the body's nutritional status. Moreover, these foods also contain cystine and cysteine, the main components of hair, making them the best nutritional foods for hair health.
