Western medicine suggests:
It is more scientific to wash your hair every other day in summer.
Some people with special jobs insist on washing their hair every day because of hygiene requirements. But in any case, you should pay attention to the choice of shampoo when washing your hair. Too alkaline shampoo should be avoided, and it is best to use conditioner again.
Chinese medicine believes that combing hair is as important as shampooing. Sebaceous glands connected with each hair constantly secrete sebum. Frequent shampooing can clean the excess sebum on the hair surface in time, eradicate the fungal culture medium, significantly reduce the generation of dandruff, and effectively increase the smoothness and easy combing of hair. If you don't wash your hair for too long, dirty hair will not only affect your appearance, but also cause dandruff, dermatitis and even hair loss. Chinese medicine advocates diligent washing and combing, especially in this era when people's pace of life is accelerating and mental workers are gradually increasing, which needs everyone's attention. Except for special people, ordinary people don't need to wash their hair every day.
Chinese medicine advice:
It is best to wash your hair three or four times a week.
Mental workers and people who work outdoors for a long time can appropriately increase the frequency of washing their hair, and in addition, they should comb it frequently to promote blood circulation.
In addition, washing your hair at night and in the morning is not good for two reasons:
The blood circulation of people who just got up in the morning has not returned to normal level, and the blood runs slowly. If you wash your hair in the morning, your head skin will be more sensitive because of the stimulation of water, and your blood circulation will suddenly accelerate. Therefore, your head will feel uncomfortable because of the sudden increase in blood flow.
At night, because of the high air humidity, it is not easy to completely dry your hair. If there is still residual moisture, when sleeping, the head will make the skin close to the pillow, so it can't be ventilated and dry. The evaporation of water only depends on body temperature, which will erode the head skin and cause discomfort to the head skin.
