Dyeing the risk of incidence of breast cancer?Doctors suggest: Don’t dye these 4 types of people

Before the 1990s, people’s requirements for beauty were not high, and they went to the barber shop to cut short or hot hair.After the 1990s, with the development of socio -economic and the prevalence of the Internet, people’s pursuit of beauty became higher and higher, especially female friends who love beauty not only exquisite makeup, but also higher requirements for hairstyles.For example, in spring and summer, the cold color system and warm color system in autumn and winter. In addition to changing their hair color according to the season, they sometimes adjust their hair color according to their own mood.

This situation can often be encountered in life: the day before seeing my friend’s hair was still black the day before, seeing her the next day, it became yellow, and after a while, it was replaced with another color.

In short, the dyeing of hair in today’s society is a common phenomenon, especially in the women’s groups, the dyeing hair is even more common for them.

Many female friends dye their hair for a while, and they are afraid of it later, because they often see news that "often dyeing hair is easy to get cancer" on the Internet. In addition, breast problems are particularly prominent.Increase the chance of breast cancer.Will the dyeing hair cause cancer?Today we will talk about this problem.

Let’s explain the concept of hair dye.Hair dye is a cosmetics for hair dyeing.It is divided into three types: temporary (one -time), semi -permanent and permanent.

The dye pigment particles used for temporary hair dye are very large, and they can only be temporarily hung in the gap between the hair scales. They cannot enter the inner layer of the hair through the surface layer.Usually, you can wash it with a hair dye with shampoo.Therefore, the damage to the hair is relatively small.

Most semi -permanent hair dye refers to plant hair dye, with fewer chemical components, and smaller dye particles. They still do not enter the deep hair department, only penetrate the hair epidermis.However, it is only more dyed than a temporary dye. It can tolerate 7-15 times to fade, and the toxicity is smaller than permanent chromosomal.

The permanent hair dye is rich in color and strong adhesion.Of course, compared to the first two hair dyes, the harm is obvious.A large amount of chemicals enter the inside of the hair, destroying the original protein chain and amino acids, making the hair dry, dangerous and elastic, and even containing carcinogens.Therefore, the health of the human body is threatened.

Let’s take a look at a study that in 2020, a study published by the National Institute of Health in the International Cancer shows that women who use dyeing agents and straight hair are compared to women who do not apply these products.The risk is high.

Researchers selected 50,000 women aged 35-75 as the research object to track them for 8 years.The results showed that within 12 months before participating in the study, women who used permanent hair dye regularly increased by 9%compared to normal women’s breast cancer.

Not only is hair dye, the risk of breast cancer often increased by women with frequent hair dyes, and the risk of illness is proportional to the use frequency of direct hair.

However, studies have found that women with semi -permanent hair dyes or disposable hair dyes have low risk of breast cancer.Therefore, we can try to use these two types of hair dye when we dye hair.

However, researchers also said that although there were many evidence that had previous evidence to support chemical hair dye carcinogens, these results needed repeated verification in other studies.And there are many factors that can induce breast cancer, not a single factor to explain the risk of breast cancer.

Therefore, we can only say that the use of permanent hair dye has a significant connection with some breast cancer (negative of estrogen receptor and progesterone receptor), which may increase the risk of onset to a certain extent.

Even though there is no clear relationship between hair dyeing and breast cancer, hair dye contains a variety of chemical components is not good for our body.Therefore, everyone can minimize the number of daily hair dye as much as possible.However, in addition to increasing the risk of carcinogenic hair dyeing, what are the harms?

Most of the hair dye is added with phenylramine. Phenylene amine plays a fixed color in the hair dye, but it is also irritating.The urgency and chronic stimulation of the hair dye will cause skin and mucous membrane damage. The scalp and hair follicles will cause inflammation. Long -term use will cause hair follicle atrophy, hair will change from thickness, and finally fall off.Therefore, people who often dye their hair will appear less and less hair, dull, and early hair loss.

It just said that hair dye contains phenylramine, which is not only irritating, but also sensitivity.There have been cases of hair dye factory employees in contact with a large number of acute poisoning of phenyline.Therefore, after the hair dye is completed, you must observe closely to see if the scalp is red, itchy, desquamation, and even the scalp and facial edema.If these symptoms appear, seek medical treatment in time.

In the end, heavy metal poisoning may occur often with hair.Although the "Cosmetics Sanitation Specifications" (2007 edition), hair dye allows containing a certain dose of mercury, lead, arsenic, but some bad businesses will add excessive heavy metals to the hair dye in order to make the coloring effect of hair dye better.

Some imported hair dye contains lead, and the lead content is 5 to 10 times that of household paint and pigments.Long -term use of these hair dyes may have symptoms of chronic heavy metal poisoning.

Seeing some people here can’t help saying that although often hair dyeing hair is very harmful to the body, I still want to dye my hair. Is there any good way to reduce the risk at the same time?Don’t worry, let’s talk about how to minimize the risk of hair dyeing.

I want to dye hair and the risk is not so great, so choosing the right hair dye is critical.At present, there are many varieties of hair dye on the market.

Regardless of which type, we must check the box carefully before buying to see if there are production batch numbers, whether the national health department is approved by the Ministry of Health, whether the safety has passed the review of the Ministry of Health, whether it has hygiene healthLicense batch number.Without these things, we must buy it carefully and choose well -known brands.

In addition to choosing hair dye that meets national production standards, you should also pay attention to less permanent hair dye.The above -mentioned research in the United States found that the risk of breast cancer using permanent hair dye will increase by 9%, and women who use semi -permanent or disposable hair dyes have not increased.Therefore, try to choose these two types of hair dye.

In addition, doctors at Peking University Cancer Hospital also said that the use of permanent hair dyes will increase the risk of women with lymphoma.It may be because the oxidant was added to the permanent hair dye, which produced new carcinogens during the oxidation process.

Not only that, the frequency of hair dye is also critical, and it is used up to 2 times a year.At present, there is no harmless hair dye in the market. If you want to reduce the risk of the body brought to the body, you must reduce the number of uses. Generally, hair dye should not exceed 2 times a year.

In addition, everyone must remember that try not to use hair dye for more than half a year.

Then, allergic testing before dyeing hair.The hair dye contains a strong pyramamine with strong sensitivity. Therefore, in order to prevent allergic reactions, it is best to do skin testing before dyeing.You can take a few drops of hair dye, a few drops of coloring agent, mix it on the inside of the arms, and then put it for 30 minutes.

If the inner skin of the arms appears red, swollen and itchy, it means that an allergic reaction occurs, and hair dye cannot be continued.If there is no obvious response after 30 minutes, you can use it safely.

Finally, after dyeing hair, you need to clean your hair many times.Although the hair is also cleaned after coloring, it is only cleaned once, and more dyeing agents will still remain on the hair, so it must be cleaned many times.

Although the above methods can reduce the risks brought by hair dye to a certain extent, most people are applicable, but these types of people are still not recommended for hair dyeing.

The first is not recommended for women who are pregnant.Because in the process of hair dyeing, some chemicals in some hair dyes are bound to be exposed to the body. If these chemicals enter the body through pores, they will be absorbed by the fetus in the body, causing the fetus to develop problems.And these harmful substances will also remain in the body of pregnant women, causing harm to the body of pregnant women.

Secondly, people who are susceptible to allergies are not recommended to dye their hair.There is a kind of people with allergies in life, and it is easy to cause allergic reactions to many items, such as pollen, dust, eggs, nuts, and so on.Regardless of what type of hair dye, it contains phenyline chemical ingredients, and phenylramine has the effect of fixing the color in the chromosomal to make the color reserve for a longer time.

However, phenyline has strong allergies. For people with allergies, allergies are prone to occur.Therefore, it is recommended that people with allergies do not often dye their hair.

Similarly, it is not recommended that the scalp is scratched or has skin diseases.Because when the scalp is scratched or dermatitis, the scalp is very fragile, and it is more sensitive to toxic chemicals.

Everyone already knows that there are many chemical components in hair dye, and even some chemical components contain certain toxins. If these ingredients are absorbed too much, it will affect human health.Therefore, it is better not to dye your hair when your hair is damaged or dermatitis, and it is not too late to dye after wound healing.

In the end, it is not recommended to dye hair with liver and kidney insufficiency.The liver has a detoxification effect in the body, and the kidney also has detoxification substances.When the body is exposed to some toxic substances, the liver and kidney need to work together to excrete it.

Once the hair dye, some of the harmful chemicals in the hair dye may enter the kidney. If the liver and kidney function is incomplete, the harmful substances are incomplete through the liver and kidney metabolism, and it will also increase the damage of the liver and kidney function.Therefore, people with liver and kidney dysfunction are often dyed.

Although hair dye does not mean that cancer occurs, from a healthy perspective, hair dye often causes a lot of damage to the body, so the number of hair dye should be reduced.For women who have a history of allergies, pregnant women, and breastfeeding, try not to dye their hair. If they want to change their hair, they can consider wearing wigs.
