Returning to the north from the south during the Spring Festival, I found more dandruff. Why?

Dandruff is a particularly annoying thing, because if there is too much dandruff, it will look particularly ugly. Excessive dandruff actually means that the human body secretes some acidic components in the process of metabolism, such as lactic acid, uric acid and phosphoric acid. These substances can not be excreted normally, but stay in the human body, which will lead to the increase of acidic substances in the human body, resulting in a lot of dandruff. Returning to the north from the south during the Spring Festival, I found more dandruff. Why?

1, climatic reasons

Different from the temperature and humidity of the air, it will affect the blood circulation of the scalp, weaken the defense function of the head, reduce the moisturizing components of the scalp, and easily stimulate dandruff.

2. Excessive sebum secretion. If sebum is secreted too much, the dead scalp cells that were not obvious will stick together and form dandruff. This kind of dandruff is usually white and small, which can cause itchy scalp and dry hair. The reason for this situation may be that the scalp part is affected by cosmetics, drugs, hair dyes and other stimuli, or it may be caused by emotional tension and too little vitamin intake.

3, tinea capitis

If you find a lot of dandruff on your head, you should know whether it is related to tinea capitis. Tinea capitis is caused by superficial fungal infection of scalp and hair. According to the different pathogens and clinical manifestations, it can be divided into several types, namely, tinea alba, tinea nigrum and favus. These types of lesions may lead to dandruff during development. After some people become tinea alba, white scaly local spots will appear. Occasionally, I feel itchy scalp, and the affected area is enlarged, which may lead to dandruff shedding. At this time, some white dandruff will appear on the head.

4. Bad living habits

Eating greasy and irritating food, staying up late, excessive stress, mental stress and other factors are all likely to lead to dandruff. Excessive dandruff usually requires a light diet, regular work and rest and a peaceful mood. You can eat some foods containing nicotinic acid B, which can regulate the metabolism of the human body. If pathological dandruff is excessive, it can be treated under the advice of a doctor. In fact, hair with too much dandruff is also very important.
