Can long term hair dye cause scalp cancer?

Since ancient times, Chinese people have regarded black hair as beauty. Nowadays, regardless of men, women and children, as long as the silver thread climbs on the head, they are afraid that they will be regarded as a sign of aging, and they do not hesitate to dye their hair repeatedly over the years of adulthood.

You know, all kinds of hair dyes contain dozens of chemical ingredients, according to the relevant departments of more than 100 kinds of hair dyes tested, nearly 90 of the hair dyes contain nitrobenzene, aniline and other toxic chemicals, easy to be absorbed, harmful to the human body. Medical experts pointed out that if you use hair dye for a long time, as long as 1 is absorbed into the human body, it will accumulate poisoning, in which chemicals combine with certain cells, and the deoxyribonucleic acid in the nucleus is damaged, causing cell mutations, and inducing ** cancer, bladder cancer, autohemorhemia, etc., experts warn against vigilance"The disease starts from the onset"。

American Cancer Society research shows that women who use hair dye have a 70% increased chance of developing lymphoma. A survey of 10,000 women with dyed hair found that they had twice as many leukemias as women without dyed hair. There is an increasing trend of leukemia caused by hair dyes, and the medical community has specially named it hair dye leukemia to remind people to pay attention.

There are also reports in medical journals in China that hair dyes cause leukemia, ** cancer, and bladder cancer. The First Hospital of Harbin successively admitted 6 patients (5 females and 1 male) with leukemia due to frequent hair dyeing; The Department of Hematology at Beijing Friendship Hospital found that many middle-aged and elderly leukemia patients had a history of hair dyeing.

Some imported hair dyes also contain lead acetate, which is 5 10 times the lead content of household paints and pigments. After lead enters the human body, it is difficult to excrete from the body, causing accumulation of poisoning, dizziness, headache, fatigue, numbness of limbs, cramping pain in the legs, abdominal pain and a series of lead poisoning symptoms, and enters the liver, kidney and cerebral marrow, destroys the function of these organs, and in severe cases, loses labor.

Because it will be absorbed through **, the poison may not be good for the body after absorption.

The use of short-acting hair dye wax chong will not be like this, especially long-acting hair dye, these hair dyes have chemical poisons, will be absorbed into the body of human pants, and those short-acting hair dyes are generally purified by traditional Chinese medicine preparations, relatively speaking, they are extracted from nature, may be plants, and the toxicity has been verified, as far as possible are edible fruits, vegetables or plant purified pigments, so the impact of short-acting hair dyes is not too large. Therefore, it is recommended that people who are willing to dye their hair use short-acting hair dye, try to choose pure natural substances, and try to choose non-toxic and harmless substances to dye their hair.

Does hair dye cause cancer?

When it comes to hair dyeing, the most common thing everyone hears is that hair dyeing causes cancer. In fact, the reason why hair dyes have a risk of causing cancer is because they contain carcinogens.

Almost all hair dyes on the market contain chemical ingredients, and these chemical ingredients are likely to cause cancer. Relevant studies have long confirmed that some inferior hair dye contains a variety of harmful substances such as benzylamines, phenols and lead, which may cause ** cancer, leukemia and so on once used for a long time.

According to studies, phenylenediamine and aminobenzene contained in hair dyes are potential carcinogens and mutagens. In addition to this, a study published in the International Journal of Cancer showed that women who used hair dye had a higher risk of breast cancer than women who did not.

Which hair dye hurts the most?

Although hair dyeing is likely to cause cancer, many people don't think so. Because of this, we need to know more about hair dyes to see which hair dye is the most harmful to people's health.

There are three main types of hair dyes, which are synthetic hair dyes, natural hair dyes, and inorganic hair dyes. Among them, inorganic hair dye is often referred to as black hair dye, which is the most harmful to human health. Because this kind of hair dye contains more heavy metal ions, such as lead, copper, iron, etc.

Once people frequently use this type of hair dye, it is very easy to cause heavy metal accumulation poisoning, aplastic anemia, system damage, etc.

The second is synthetic hair dye, which can cause ulcers and pigmentation if used for a long time. Finally, the least harmful to the human body is natural hair dye, but its tinting strength is relatively poor, and many people do not like to use this type of hair dye.

Although hair dye is a chemical, it is temporary, and can change the hair to other colors, but the substance contained in hair dye generally contains phenylenediamine, which is a necessary substance in hair dye, which is internationally recognized as a carcinogenic substance. Nowadays, for the people who dye their hair, it is not only limited to middle-aged and elderly people, but this development trend is more and more towards young people.

Hair dyeing can cause cancer. First of all, it is the consensus of the medical community that the chemical raw material hair dye is harmful to the human body, and the hair dye is mainly made of aniline, which has the advantages of bright color, washability, and light resistance, so it is widely used at present. According to the chemical properties of the dyes, they can also be divided into nitro, azo, anthraquinone, indigo and aromatic.
