There are many reasons for children’s dandruff, which may be related to inadequate cleaning and fungal infection, and can be improved by warm water cleaning, adjusting dietary structure and medication. 1. Warm water cleansing: some children with more dandruff are considered to be related to incomplete cleansing, which can be cleaned with lukewarm water, and at the same time need to use children’s special shampoos, avoiding over-cleansing or over-alkaline shampoos. 2. Adjust the diet structure: avoid eating too much greasy food, fresh vegetables and fruits, and eat a light diet. 3. Medication: If the dandruff is still high and the itching is obvious, consider the possibility of fungal infection, and use ketoconazole cream externally as prescribed by the doctor. If children have more dandruff, it is recommended to consult a doctor to clarify the cause of the disease and actively cooperate with the treatment.
