Night Listening | How often should you wash your hair? Is it better to wash it in the morning or at night?

Hello, this is Science Popularization China. I don't know if you have ever been troubled by washing your hair. If you wash your hair in the morning, you always feel a little dizzy. If you wash your hair at night, you may catch a cold if you go to bed with wet hair. Moreover, it is difficult to master the frequency of washing your hair. Today, let's learn about the correct posture for washing your hair.

In fact, the frequency of hair washing varies from person to person, so it cannot be generalized. If you have oily hair or are prone to dandruff, wash your hair more often. Especially in summer, when your head is prone to sweating, it is not too much to wash your hair every day. It is said that you can wash your hair every day, but it does not mean that you have to use shampoo and conditioner every day. You can just rinse it with water every other day depending on the situation.

Will washing your hair every day damage your hair? In fact, scientists have studied this issue a long time ago. In 2021, an article was published in a medical journal called "Disorders of Skin Appendages", which compared "people who don't wash their hair for a week" with "people who wash their hair every day". It was found that washing your hair more often can reduce scalp itching, and the hair quality will not be significantly damaged.

If your hair is less oily and has neutral or dry hair, you can reduce the frequency of washing your hair appropriately. 2 to 4 times a week is enough.

As for the time to wash your hair, it can be done in the morning or evening. However, when we just get up in the morning, our blood pressure and blood circulation have not yet recovered. If we lower our heads to wash our hair at this time, we are prone to dizziness. Some people rush to work or school after washing their hair, and their hair and scalp are wet and easily irritated.

If you wash your hair at night, it is best not to wash it right before going to bed, and leave some time for your hair to air dry. Otherwise, if you go to bed with wet hair, it will damage your hair and may cause colds, headaches and other problems.

If you have never encountered any of the above situations, then wash it whenever it is convenient.
