Hair loss in children is generally due to relatively simple reasons, mostly related to irregular eating habits or picky eating, and malnutrition. According to traditional Chinese medicine, this may be caused by a deficiency of both qi and blood. Therefore, when hair loss is noticed in children, it is advisable to visit a formal medical institution to get a blood test for trace elements to see if there is a deficiency of certain substances. Additionally, some children may indeed have internal diseases, such as kidney or liver diseases, which can lead to physical weakness and hair loss. In most cases, mild hair loss in children does not require special treatment and can gradually improve by adjusting diet and lifestyle habits.
