Many people are always troubled by the dandruff in winter, as it is difficult for people to remove dandruff from the head. In order to remove the dandruff, it is important for people to know well about the formation of dandruff. 

The formation of dandruff is caused by the unhealthy situation of the scalp cells. Under the normal circumstances, the metabolism cycle of the scalp cells is 28 days.

In everyday life, people should increase the intake of alkaline foods, such as milk, vegetables, fruits and seaweed food. The intake of acidic foods should be strictly controlled. The foods containing vitamin B2 (riboflavin) and vitamin B6 should be supplemented in daily life. In addition, people should avoid fried foods and spicy or pungent foods like wine, coffee and so on.
