Xiao Wei found that since she began to wash her hair at night, her hair situation had become worse and worse. For example, after washing your hair the night before, the next day you get serious oil. After washing your hair every day, the hair hurt more, and the hair loss seems to be getting worse.
Xiao Wei checked on the Internet, some people said that you can't wash your hair at night, some people say you can't wash your hair in the morning, and some people say that washing your hair every day, your hair will really become more and more oily, and it will also aggravate the possibility of hair loss and dandruff. At this point, Xiao Wei didn't know what to do at all.
First, wash your hair in the morning or wash your hair at night, which is better?
Wash your hair also depends on the auspicious time? In the matter of washing hair, there are two "factions" that are the most controversial, one faction insists that washing hair in the morning is not good, and the other faction believes that washing hair at night is unhealthy. What is the specialty of washing hair in the morning and evening?

In the morning, blood circulation has not yet returned to normal levels, blood flow is slow, this time to wash the hair, water flow stimulates the scalp, will accelerate the flow of blood to the brain, causing dizziness, headaches and so on.
Truth: In fact, as long as you don't get out of bed, you can wash your hair, or wash your hair with too cold, too hot water, this situation can be avoided.
Recommendation: Brush your teeth and face after getting up, wait for the blood to gradually warm up, and then wash your hair again. It is more appropriate to control the water temperature of the shampoo at 40 ° C, and after washing the head, it must be thoroughly dried with a hair dryer before going out.

Wash your hair at night, the moisture in the pores of the scalp is not completely volatilized, which can easily lead to chronic headaches, colds...
Truth: The main guarantee is not too late to wash, the water temperature is appropriate, and the hair is wiped and blown dry before going to bed, there is basically no problem.
Recommendation: It is best not to wash your hair before going to sleep, be sure to blow dry your hair thoroughly after washing your hair, and do not go to sleep with wet hair.
Second, why wash every day, the head is still very oily?
Xiao Jiu's colleagues often complained to Xiao Jiu, their hair was greasy, they washed their heads in the morning, they went out, and they were oily in the afternoon, looking dirty.
Why do people wash their hair every day and their hair is still oily? In the final analysis, in essence, there are still problems with the "soil" of the scalp, and there are generally 3 reasons.
The first is scalp properties. The human scalp is mainly divided into oily, neutral and dry. On the second day of shampooing, you can observe the oil scale or itching of the scalp, which can be basically judged as oily scalp.
The second is bad habits such as staying up late and loving to eat high-oil foods. Many people find that if they stay up late the night before, their hair will turn oily the next day. The oil or dryness of the scalp depends mainly on the sebaceous glands distributed in the scalp. Poor life, eating habits, and stress can stimulate the sebaceous glands and speed up their secretion.
The third is the level of androgens in the body. The degree of secretion of the hair follicle sebaceous glands is also related to hormone levels, especially androgen levels. Therefore, relatively speaking, the hair of men during development, during menstruation or pregnancy, is prone to oil.
At the same time, oil secretion is easy to breed some bacteria or fungi, such as Malassezia, which can cause local seborrheic dermatitis, leading to dandruff, acne and other problems.
Third, how often is it good to wash your hair?
Many people wash their hair diligently in order to ensure that their hair is clean.
In fact, for different hair types, the number of shampoos can be different. Oily hair can be washed daily or every other day; dry hair can be washed once every 3 to 5 days.
Some people worry that washing their hair every day will cause the hair to fall out more and more, and it will be embarrassing to wash it until the hair is lost. In fact, washing hair and losing hair is more because of hormones, endocrine, mental and other factors. Falling off is a matter of sooner or later, if healthy hair, it will not fall out because of the intensity and irritation of washing hair.
The same is true for dandruff, scalp cells are very "short-lived", generally 28 days on the replacement of the fall off. In fact, 90% of dandruff is physiological and belongs to normal metabolism.
Fourth, wash your hair, 99% of people did not do it right
Everyone has some preferences when washing their hair, but these common small habits can lead to damage to scalp hair:
1. Shampoo poured directly on the scalp
Many people try to save trouble, pour shampoo directly on the top of their heads, and then rub it. Any shampoo is essentially inseparable from chemical agents, and direct contact with the scalp will irritate the scalp, which may cause harm in the long run.
2. Apply shampoo when the hair is just wet
Many people get their hair slightly wet and start applying shampoo to their hair, so there's no way to wash it off adequately. Before applying shampoo, rinse hair and scalp for more than 1 minute to remove 70% or 80% of the dirt, and then apply the foaming shampoo to the hair.
3. Do not dry immediately after washing
After washing the hair, choose natural air drying, which is known as less damage to the hair. But during this process, the hair keratin affected by the heat is in an open state, and it is easy to get dirty things such as dust in the air. The moisture on the surface of the hair should be dried by a hair dryer first, and then blown with a cold air stall for a while to close the stratum corneum.
4. Conditioner to apply to the scalp
Many people think that the longer the conditioner stays in the hair, the softer the hair will be. In fact, applying conditioner for a long time will not improve the absorption effect, and most conditioners can only be used for the ends of the hair. Directly applied to the scalp, it is easy to cause irritation, blockage, damage to the ecological balance of the scalp, causing inflammation and other problems.
Wash your hair, whether in the morning, at noon or at night, as long as you are not unwell, you can wash it at any time. Moreover, the claim that washing too much hair can lead to hair loss and dandruff is unscientific.
