There are more reasons for the increase of dandruff, and many people are emotionally depressed and anxious because of excessive mental tension, such as working badly or arguing with others, while uncoordinated sleep and frequent late nights are important reasons for the increase of dandruff. In addition, there is not enough attention to diet, such as often eating barbecue or eating hot pot and other spicy and irritating foods, which may also cause an increase in dandruff on the scalp. In some cases, if there is inflammation of the scalp, such as the occurrence of seborrheic scalpitis, or fungal infection of the scalp, such as the occurrence of ringworm, are among the important factors that lead to increased dandruff. In case of increased dandruff, it is recommended to go to the hospital for early treatment.
