The treatment of dandruff can be supplemented by internal medication, such as vitamin B6 and thyroxine tablets, and the decoction of Chinese chrysanthemum and peach leaves in appropriate amounts to wash the hair is also effective. Usually pay attention to the hygiene of the scalp and wash your hair with warm boiled water frequently, once a week in general and once every 3 or 4 days if necessary. You should not use alkaline soap when washing your hair, because alkaline soap will stimulate cellular keratinization on the scalp and produce dandruff, you can use sulfur soap, or shampoo to wash your hair. Excessive dandruff should avoid eating fried, greasy, spicy, alcoholic and caffeinated foods. Quit eating overly sweet foods, because hair is alkaline and desserts are acidic, which will affect the acid-base balance in the body and accelerate the production of scalp, and do not pour shampoo directly on your head.
