If you want to know how much your partner cares about you, just check whether he/she washes his/her hair before going out.

As people pay more and more attention to their appearance, washing hair has become a part of social etiquette. Many netizens said that today's interpersonal relationships can be divided into three types:

First, you can meet without washing your hair;

Second, you have to wash your hair before you can meet each other;

The third is that I don’t want to see you even after washing your hair.

Washing hair brings a lot of troubles to people with hair loss, such as how to reduce hair loss, whether there is a relationship between the number of times hair is washed and hair loss, etc.

I'm quite "bald". Every day I count the hair I lose and fall into deep thought... There is actually a lot to this small matter of washing hair.

Is it better to wash your hair more often?

First, we need to understand the physiological knowledge of hair health.

Our hair grows from the follicles in our scalp, which is also our skin. Therefore, the health of our scalp and hair follicles determines the health of our hair.

Many people know that excessive facial cleansing can cause dryness and flaking of the facial skin. In fact, the same is true for the scalp.

If we wash our hair frequently, shampoo and other detergents will over-clean the scalp, which will cause the scalp environment to be too dry and may cause excessive stimulation to the hair follicles. This series of effects may cause disorders in the cell metabolism of the hair follicles, resulting in dandruff, itching and even hair loss.

So, how often should we wash our hair?

Everyone's scalp condition is not exactly the same. The amount of oil produced by the scalp is related to the body's hormone level. The higher the androgen level, the more oily the scalp is and the more frequently it needs to be cleaned.

Therefore, the frequency of washing our hair should be determined according to the oiliness of our hair. If you feel that the roots of your hair are greasy, your head is itchy, or even has an odor, then you need to wash your hair.

In addition, the frequency of hair cleaning is also related to the season. Our sebaceous glands are affected by the humidity and temperature of the environment. The higher the temperature and the greater the humidity, the more oil the scalp produces. Therefore, you can wash your hair more frequently in the summer and less frequently in the winter.

Is it better to wash your hair in the morning or at night?

This should be determined based on actual needs.

Wash your hair in the morning

This method is more suitable for two types of people:

The first category is people who need to style their hair before going out. From an aesthetic point of view, it is more suitable to wash their hair in the morning.

Another type is people with long hair that is not easy to dry. If you wash your hair in the morning, you won't go to bed with wet hair.

Wash your hair at night

From a hygienic point of view, we run around outside all day, and a lot of dust and bacteria will be absorbed on our hair. Therefore, washing your hair and taking a bath at night can make our sleeping environment cleaner and more beneficial to our health.

But it should be noted here that you should blow dry your hair before going to bed, otherwise it may cause headaches or some other health problems.

The more often you wash your hair, the more hair you lose?

Some people may say that frequent hair washing will increase the amount of hair loss, so you should not wash your hair if you can.

In fact, this idea is wrong.

If you always wait until your hair is very greasy before washing it, it will not only have a great impact on your image, but also cause bacteria to multiply on your scalp, which will affect the health of your scalp and cause problems such as dandruff and hair loss.

What really causes hair loss is not washing your hair, but the wrong way of washing your hair and the wrong use of products.

1. When washing hair, we should comb the hair with a comb before washing, especially for friends with long hair. This step can not only facilitate the subsequent thorough cleaning of the shampoo, but also avoid physical hair loss caused by hair tangling and pulling.

2. The water temperature for shampooing should not be too hot or too cold. It should be close to the temperature of the scalp, or slightly hotter than the scalp.

3. When washing hair, we should first make shampoo into foam, and then apply it to the hair for cleaning. This can avoid excessive shampoo concentration in the local area, which will cause excessive stimulation to the scalp.

4. When cleaning your scalp, be sure to massage with your fingertips instead of scratching with your nails, otherwise it may cause tiny wounds on the scalp and cause bacterial infection.

5. If you are used to using conditioner, please note that you should not apply the conditioner on the scalp. Use it on the back half of the hair near the ends of the hair and then massage gently, and then rinse with clean water.

Also, be aware that your scalp, like your facial skin, may have sensitive reactions to certain ingredients.

Therefore, if you use a certain brand of shampoo and suddenly experience increased dandruff or discomfort, it may be an allergy. Stop using it or switch to another brand in time.
