On February 2, the dragon looked up.
Every year on the second day of the second month of the lunar calendar, it is a day commonly known as "the dragon raises its head", and of course, it is also a good day for uncles, and after a month of "nephew threat" worries, it can finally be liberated.
When it comes to the dragon looking up, the natural custom is to shave the head.
Therefore, this day is also the "God of Wealth Day" of many barbershops, and everyone wants to trim their hair and pray for a good color head every year.
Does dyeing hair really hurt the human body?
For the middle-aged and elderly people, hair coloring can cover some white hair, while young people dye their hair to show their personality.
But dyeing hair is like opening a blind box, playing is a heartbeat, originally full of expectations to wash off the hair dye cream on the head, blow dry hair and then look at the mirror, the result is not a beautiful to cry admiration, but accompanied by grief-stricken pain-----
Why is it not the same as the picture?!
But there are also many people who have heard about the harm of hair coloring, what carcinogenic theory, infertility theory... It causes many people to be afraid of hair coloring, and even fear of being too close to the hair dye person, so as not to be "infected" by the hair dye.
However, is this really the case?
Hair dyes, can really cause cancer?
As early as September 2020, U.S. scientists tracked 120,000 U.S. female nurses for 36 years, and the results showed that ---- there was no association or poor association between the use of permanent hair coloring and most cancers.
But at the same time, the researchers also found that stains increase the risk of developing certain tumors, such as base epithelioma, breast cancer and ovarian cancer.
However, this study is only observation and record, the specific pathogenesis has not yet been explained, so we can know that --- hair dye is risky, but there is no need to worry too much about it will cause cancer.
Therefore, if you only dye your hair occasionally, it is only 1-2 times a year, and you use qualified products on the market, you don't have to worry about the "carcinogenic" thing.
Unqualified hair coloring is indeed very hurtful
Hair dyes are divided into plant hair dyes and chemical hair dyes, and the raw materials used in plant hair dyes are substances extracted from the flowers, stems and leaves of plants.
This hair dye is basically harmless to the human body, but the price of this plant hair dye is relatively expensive, and the color is very single, for most people, this hair dye is rarely used.
Most people use a hair dye for chemical hair dye, chemical hair dye is a combination of various chemical components of the hair dye, contains a large number of chemicals, many of which are strong carcinogens.
In the process of hair coloring, these chemicals will enter the human body through the pores on the scalp, which will have a certain impact on the body.
What are the potential risks to the body from substandard hair dyes?
1. Risk of allergies
Chemical hair dyes contain a substance called phenylenediamine, which can cause very much damage to the body's skin.
In the process of hair coloring, this substance is easily exposed to the skin, which will cause strong irritation to the skin. Especially when the hair dye is used in the wrong way, or the hair coloring method is not correct, and the immunity is weakened and it is easy to be allergic.
Mild cases can cause redness, swelling, tingling, and itching sensations in the scalp of the person.
If the condition is serious, the entire scalp, neck and eyelid area of the hair dyeer will have serious swelling, yellow water, and even purulent infection.
2. Risk of liver and kidney damage
The phenylenediamine components contained in substandard hair dyes are not only allergenic, but are also absorbed through the skin and enter the blood circulation, and then flow into the liver and kidneys.
Once this component enters the liver and kidneys, it is difficult to be excreted, and it will cause a certain degree of damage to the liver and kidney system for a long time.
Third, the risk of carcinogenicity
Unqualified hair dyes contain some carcinogens, amphetamines belong to a strong carcinogen, and another 2-4 aminoanisole is also a strong carcinogen, which is easy to accumulate in the human body.
Once the excess enters the human body, it will lead to abnormal cell proliferation. The benzene substances in the hair dye will enter the capillaries and reach the bone marrow, which can easily induce leukemia.
How to reduce the damage of hair coloring to the body?
Although hair coloring may have an impact on health, before hair coloring, we only need to choose a qualified hair dye, operate in strict accordance with the specifications during the hair coloring process, and repeatedly confirm that it is cleaned, as long as it is not frequently colored, there is still no big hidden danger.
If there is an allergy and other discomfort after hair dyeing, it is necessary to wash off the remaining hair dye as soon as possible, and if the situation is serious, you need to cut off the hair that has been dyed, and seek medical treatment in time to effectively treat it under the guidance of a doctor.
After all, dyeing hair is just for a happy and beautiful picture, but if you let the body take a big risk because of this, it is really not worth it!
