I have a lot of dandruff in winter. What should I do? What's going on here?

Dandruff is a chronic skin disease, which is harmless to the body. Skin cells are constantly updated and metabolized on the scalp, so it is normal for dead skin cells to fall off. However, sometimes because scalp cells renew and fall off faster than normal, scalp oil will cause dead skin cells to gather together and appear white flakes. The deterioration of flaky dandruff will cause some people to lose their hair. Avoid eating fried greasy and spicy foods, get enough sleep, don't stay up late, eat more alkaline foods, such as kelp and seaweed, and often drink fresh milk, beans and fruits, all of which have the effect of nourishing hair. Dandruff can usually be controlled by proper treatment. Try washing your hair with non-medicinal shampoo, massage your scalp hard, and then rinse it off. Frequent shampooing can remove dandruff, reduce scalp oiliness and prevent the accumulation of dead skin cells. If this doesn't work, change to a special dandruff shampoo.
