Question
My child’s hair is dry and yellow, and the trace element test is normal. What aspects should I be aware of? Are there other diseases that could be possible? In addition, I would like to ask which vitamin is better for improving hair condition? Besides walnuts, what other nut foods are beneficial?
Answer
Yellow hair may be due to hypothyroidism, severe malnutrition, iron deficiency anemia, or reduced body melanin after recovering from a serious illness. Additionally, frequent hair straightening and the use of laundry detergent or alkaline shampoos may also cause hair damage and yellowing. In cases of nutritional hair yellowing, it is important to improve the nutritional status and supplement foods rich in animal and plant proteins, such as eggs, lean meat, soybeans, peanuts, walnuts, and black sesame seeds, which contain necessary components for hair structure like cysteine and cystine. For specific vitamin supplementation, it should be determined based on individual conditions and nutritional assessment. Besides walnuts, other nut foods include almonds, hazelnuts, and pistachios.
