Washing your hair is a very daily thing and something that everyone can do.
But it is precisely this kind of daily thing that sometimes does wrong but is detrimental to health.
Recently, a 31-year-old girl in Hengshui, Hebei Province, suddenly found that her mouth was crooked and her right eye could not be closed to the hospital for treatment, and after examination, it was found that the patient had idiopathic facial paralysis.
After inquiring in detail, it was found that the girl had rushed to ride to work the night before after washing her hair and not blowing dry, which caused facial paralysis.

Why does washing hair without blowing dry cause facial paralysis?
In fact, cases of facial paralysis occur many times in the summer.
Since the body is more prone to sweating in the summer, the pores are in a state of expansion at this time. Long-term wind blowing will cause the blood vessels to contract violently, and over time, it will cause local swelling and compression of the facial nerves, which will cause facial nerve paralysis.
And this woman may wash her hair and ride directly, under the stimulation of hot and cold, it will cause facial paralysis.

If you don't wash your hair well, it will also hurt your body
For this kind of daily thing, there are also many details to consider in washing hair. However, some people believe that the washing time is exquisite, and if the time is not right, it may hurt the hair or human health.
Wash your hair in the morning and wash your hair at night, which time period will be better?
In fact, the time to wash your hair is really not so strict.
Some people think that getting up in the morning to wash their hair can start a new day of work and life refreshed; some people think that washing their hair before going to bed, clean and sharp into the bed to prepare for rest and sleep.
Therefore, if you already have the habit of fixing the washing time, and there is no discomfort after washing your hair, you can completely combine your own time plan to wash your hair, and there is no "best time".
However, it should be emphasized that although the shampoo time is not stipulated, the water temperature for shampooing needs to be kept moderate.
Excessively hot water will relax the blood vessels on the surface of the scalp, too cold water will stimulate blood vessel contraction, and excessive relaxation or contraction of blood vessels will cause physical discomfort.
For patients with cerebrovascular disease, too cold and too hot water temperature may stimulate the occurrence of the disease, resulting in dizziness, headache and other phenomena.
In addition, after washing your hair, be sure to blow dry your hair, and you need to wait until your hair is completely dry before you can go out or sleep. If the hair is wet, the water evaporation will take away the heat of the head, causing the blood vessels in the scalp to be stimulated by heat and cold, resulting in health risks.
How often is it best to wash your hair?
In fact, there is no particularly accurate statement about how often to wash your hair, mainly depending on what kind of hair quality you have.
1. Oily hair
If it is oily hair, the scalp often produces oil, causing the hair to look greasy, then washing the hair once a day is enough.
Because the hair and scalp cannot be cleaned up in time, the oil may clog the hair follicles, affect the absorption of nutrients by the hair, and even lead to hair loss.
2. Dry or neutral hair
If the amount of oil produced by the hair is not large, then it is a neutral or dry hair. In this case, it is better to wash your hair every two or three days.
If your hair loss is more serious, you can appropriately reduce the number of shampoos and choose a suitable shampoo.
Some people may have cleanliness habits and have already washed their hair once in the evening bath, but when they wake up the next morning, they must wash their hair again.
In fact, such an approach is wrong.
If you wash your hair too many times a day, it is easy to damage the sebaceous glands on the scalp, resulting in a large reduction in oil, so the scalp and hair will lose their natural protective film, thus causing greater damage to hair quality.
Wash your hair and don't push too hard
Some friends think that scratching the scalp with fingernails will feel very comfortable and refreshing.
But in fact, rubbing and pulling too hard may inadvertently scratch the scalp, causing inflammation on the scalp, or irritating the damaged hair follicles, causing hair loss.
It is recommended that during the shampooing process, the force is moderate, and the scalp and hair are gently rubbed from front to back with the fingers, and the shampoo needs to be fully washed and cleaned, so as not to have residues, so as not to damage the hair texture, cause hair loss and hair loss.
