"Don't dye your hair anymore, or it will induce cancer!"

Uncle Liu is 52 years old, and although he is not very old, his hair so much turned white. This white hair makes Uncle Liu older, and for this reason, he started to dye his hair. After dyeing his hair once, his hair will lose its color in about 3 months, so Uncle Liu dyed his hair every 3 months.

Unbeknownst to him, 3 months had come and Uncle Liu then started to dye his hair. After the neighbor saw Uncle Liu dyeing his hair, he was worried for him, so he said the words at the beginning of the article to Uncle Liu. After hearing the neighbor's words, Uncle Liu did not think it was a good idea and told the neighbor that several of his relatives had dyed their hair for more than ten years without getting cancer. The neighbors felt that persuasion was fruitless, and stopped talking.

There are always different voices about whether hair dyeing causes cancer or not. Does hair dyeing cause cancer or not? Is it dangerous to health? To let you have more knowledge and understanding about hair dyeing, today the doctor's good advice will have a good chat with you about related knowledge.

1. After 8 years of hair dyeing, Ms. Wang was found to have leukemia!

Ms. Wang is a person who likes fashion, and to make herself look more trendy, she often dyed her hair. The frequency of hair dyeing is not fixed, sometimes twice a month, sometimes 4 times a month.

So unknowingly 8 years have passed, and Ms. Wang has been dyeing her hair frequently. However, in recent times, Ms. Wang always had nosebleeds. At first, she thought it was because of staying up late, as long as she rested well, she would not have a nosebleed. However, after she rested for 3 days, she still kept having nosebleeds. As a last resort, Ms. Wang went to the hospital.

After fully understanding the situation, the outpatient doctor gave Ms. Wang a rhinoscopic examination, which also did not reveal any broken blood vessels. To rule out blood system diseases, the outpatient doctor prescribed routine blood tests and coagulation tests for Ms. Wang. After the test results came out, it was found that the white blood cells were particularly high, other blood cells were low, and the coagulation function was normal, so the preliminary consideration was hematologic disorders.

Subsequently, the outpatient doctor told Ms. Wang that the diagnosis of any hematologic disorder could not be confirmed yet. To confirm the diagnosis, she would need to be hospitalized and then have a bone marrow aspiration test. Ms. Wang realized the seriousness of her condition, so she followed the outpatient doctor's advice. Afterward, Ms. Wang underwent a bone marrow aspiration, and the results came back indicating lymphocytic leukemia.

When Ms. Wang learned of the results, she was particularly uncomfortable and asked the doctor if she had been misdiagnosed. When the doctor heard Ms. Wang's question, he explained that the bone marrow aspiration test is the gold standard for confirming leukemia, so the chance of misdiagnosis is relatively low.

2. Is it true that frequent hair dyeing can cause cancer?

Some people believe that hair dye is carcinogenic, mainly because hair dye contains p-phenylenediamine, which is itself a carcinogen.

There is no denying that p-phenylenediamine is indeed classified as a carcinogen, but there is still a lack of strong evidence that hair dyeing causes cancer. This is mainly because cancer is the result of a combination of factors, and hair dyes need to meet a certain dose to cause cancer, otherwise, it is a hooligan to talk about cancer without the dose.

At the same time, the relevant authorities have also taken into account the carcinogenicity of p-phenylenediamine, so there are strict requirements on the amount of p-phenylenediamine in hair dyes. The regular hair dyes on the market are tested by the relevant departments, so the content of p-phenylenediamine in these dyes is also in line with the national standards.

Some friends may have questions, since p-phenylenediamine in hair dyes is a carcinogen, then why do you still use this substance? This is mainly because p-phenylenediamine is a relatively important dye, which has a strong affinity for hair. If p-phenylenediamine is not used in hair dyes, it will be difficult to fix the color of the hair.

It is important to note that regular hair dyes are not carcinogenic, but it is hard to say about informal hair dyes.

Some hairdressers may use poor-quality hair dyes for their customers to pursue high profits, and poor-quality hair dyes may have cancer risks. Some friends will find an unpleasant smell on their heads after they dye their hair, and such hair dyes may contain benzene and benzene substances.

When you dye your hair with a hair dye containing benzene and benzene substances, the benzene and benzene substances contained in it may enter your body. When hair is dyed, the hair may be heated, so benzene and benzene substances are more likely to enter the body. Long-term use of this hair dye may cause benzene and benzene substances to enter the bone marrow, thus increasing the risk of leukemia.

Regular hair dyes are not carcinogenic, but irregular ones are not so good, depending on the ingredients.
