What is the reason for dandruff in winter? What is the reason for dandruff on the head in winter?

Everyone wants to have bright black hair, but in winter, the weather is cold and dry, and many people will have the problem of increased dandruff. What is the reason for the increase of dandruff? Why does dandruff increase in winter?

Climatic reasons

In winter, the temperature and air humidity decrease, affecting the scalp blood circulation, disrupting the rhythm of scalp metabolism, affecting the defense function, not ensuring the moisture of the skin, reducing the moisture content of the scalp, not fully nourishing the hair, and stimulating the generation of dandruff.

Too little shampoo

Compared with other seasons, people wash their hair less in winter. If they don't wash their hair for a long time, it is easy to breed all kinds of bacteria, especially dandruff Bacillus, which will lead to an increase in dandruff.

Improper shampooing method

The biggest feeling that winter brings us is cold. Many people like to soak their feet and take a hot bath, and even use boiled water when washing their hair. But the higher the water temperature, the more sebum they wash away, and the easier it is for the scalp to dry. Generally, the water temperature of shampoo is 40℃, not too high. In addition, if you are used to scratching and washing your scalp with your nails, it is easy to hurt your scalp and then dry it, leading to dandruff.

Dietary factors

In the cold winter, people tend to choose some spicy food to warm their bodies, but if they eat too much, they will also produce dandruff. In addition, vitamins are essential nutrients for hair and scalp. If the nutrients are insufficient, it will cause problems such as scalp dryness and hair loss.
