“I heard that shampooing during menstruation can cause cancer, is it true? I recently came to my aunt, but my hair is too oily to wash, what should I do?”

< span>The backstage received a private letter from a female fan. If you want to talk about shampooing, you need to pay more attention to it. There are many folk sayings about shampooing. Washing your hair will wash away the yang energy…is this true?

1. Does shampooing during menstruation really cause cancer in women?

There is such a saying on the Internet: It is taboo for women to wash their hair during menstrual cramps, because water on the scalp can affect the uterus, slow down contractions, and affect the expulsion of dirty blood, which remains in the uterus and accumulates over time. , can disrupt endocrine, and ultimately lay a hidden danger for the development of breast cancer and uterine cancer.

In response, Director Wang Donghong, a gynecologist at the Eye Hospital of the Chinese Academy of Chinese Medical Sciences, said, There is no scientific basis for not washing your hair during your period.

The color and quality of women’s menstrual period are maintained by the function of the hypothalamus-pituitary-ovarian gonadal axis.The process of menstruation is based on It is produced on the premise of the normal operation of the human endocrine system. Its driving force is hormone stimulation, and it will not be changed by bathing and washing hair.

As for the “dirty blood” during menstruation, that is the concept of stealing. Menstrual blood is the periodic shedding and bleeding of the endometrium due to the changes in the hormone cycle in the body. These menstrual blood contains substances such as blood, endometrial fragments, cervical mucus, etc., which are the normal physiological tissues of the human body. It is a part of the human body, it is not “dirty blood”, and there is no possibility of cancer.

In fact, women need to wash their hair more during menstruation. You must know that most of the “oil” on the scalp comes from the sebaceous glands, and hormone changes are one of the factors for the secretion of the sebaceous glands.Women who are menstruating have a strong secretion of estrogen, which is often more likely to cause the scalp to break out.” Oil”.

Second, when should I not wash my hair? When should I wash my hair?

If you have greasy hair and itchy scalp, everyone will wash their hair consciously. Many fans asked Xiao Ai, I heard that shampooing in the morning is easy to “get off the wind” and “remove the yang”. Is it more suitable to shampoo at night? But there are many people who feel that washing their hair at night is easy to have a headache. Is it better to wash your hair in the evening or in the morning?

Actually, you can.

1. Morning:

For people with underlying diseases, such as high blood pressure , coronary heart disease, arteriosclerosis, etc., blood pressure fluctuates greatly after waking up in the morning, washing your hair at this time is prone to accidents, so it is not recommended to wash your hair in the morning . For healthy people, there is no scruples about shampooing time. If you are used to washing in the morning, just follow your own preferences.

2, Evening:

I want to emphasize here that you must pay attention to drying your hair when you wash your hair at night! Many people are used to shampooing their hair before going to bed, but sometimes it is too late to dry and fall asleep. This behavior can cause a lot of damage to the body.

First, sleep with wet hair, the water cannot evaporate, and it is easy to catch a cold. Second, the wet hair stays on the surface of the scalp for a long time, which will affect the brain circulation and cause Headache. More importantly, when you sleep at night, the facial nerve is in a relaxed state, and the scalp moisture can affect the facial temperature and the facial nerve behind the ear, which can cause local spasm and induce facial paralysis .

There is no absolute taboo or the best time to wash your hair, You can wash your hair whenever you want, as long as you feel comfortable, but Remember to blow dry before going out or going to sleep, or you may leave a health hazard.

Third, the hair is naturally air-dried and blow-dried, which is better?

Studies have shown that air-drying is better than blow-drying.

Dry naturally, its fur and hair quality keep shrinking simultaneously, hair is not easy to break< /strong>. But dry it naturally, it is not friendly to eating long hair, and the hair that reaches the waist wants to dry naturally, It will take at least about 1 hour , In addition, when drying, if you keep combing your hair with a comb, the friction force on the hair is very large, and the hair is also relatively fragile at this time, and it is easy to damage the hair.

and use a hair dryer to dry the hair, the outer fur dries faster , but the hair medulla and cortex inside cannot be “taken into account”, it will dry slightly slower, and it is easy to form a difference in internal and external pressure, which will lead to a decrease in the elasticity of the hair cape.headHair breaks easily.

Here Xiaoai gives you a reference suggestion:

If you like to dry it naturally, you can use it first after washing your hair The dry towel absorbs excess moisture and then air-dries, being careful not to comb repeatedly during the process.

If you like to blow dry with a hair dryer, it is recommended to use a dry towel to absorb water first, then adjust the hair dryer to a medium-low setting. It is best not to use cold or hot air to blow your hair. When it is blown to about 80% dry, the remaining water can be evaporated naturally.

Fourth, is it better to wash your hair or take a bath first?

Do you wash your hair or shower first? What exactly is the correct order?

Associate Professor Ye Tian, ​​Department of Dermatology, Affiliated Hospital of Traditional Chinese Medicine, Southwest Medical University pointed out that you should take a bath before washing your hair.

The correct order is: wash face→bath→shampoo

< span>After taking a bath, the water vapor in the bathroom is equivalent to doing a SPA on the scalp, the hair is fully moisturized, it is not easy to get knotted, it also helps the absorption of the conditioner, and it helps nourish the hair.

In fact, for middle-aged and elderly people, it is more suitable to take a bath and then wash your hair. Because the scalp is rich in blood vessels, going into the shower to wash your hair directly with hot water may cause blood flow to concentrate on the head, which is prone to cardiovascular accidents. If you take a bath first, you can let the whole body have a process of adaptation. After the scalp adapts to the temperature, you can wash it, which is clean and safe.
