The dangers of hair dyeing

The 21st century is a quiet and peaceful era. In peaceful times, people begin to have many pursuits and enjoyments in their lives. People pursue fashion and beauty. For people who pay attention to appearance, pursuing trends is something they follow every day. Nowadays, people are no longer satisfied with their shiny black hair, and instead dye their hair in various different colors.

In today's society, as long as you walk on the street, you can find people with colorful hair everywhere. It seems that after dyeing their hair, people become more confident and look so energetic. However, everyone knows that dyeing hair requires the use of some pungent-smelling liquids, so is this not harmful to people?

Various hair dyes contain dozens of chemical ingredients. According to tests conducted by relevant departments on more than 100 types of hair dyes, nearly 90% of them contain toxic chemicals such as nitrobenzene and aniline, which are easily absorbed by the skin and cause harm to the human body. Medical experts point out that if hair dye is used for a long time, as long as 1% is absorbed into the human body through the skin, it will accumulate and cause poisoning. The chemical substances will combine with certain cells, damaging the deoxyribonucleic acid in the cell nucleus, causing cell mutations and inducing skin cancer, bladder cancer, leukemia, etc. Therefore, experts warn to be vigilant about "diseases entering the body through hair."

Research by the American Cancer Society shows that women who use hair dyes have a 70% increased chance of developing lymphoma. A survey of 13,000 women who dyed their hair found that the rate of leukemia among them was 3.8 times that of women who did not dye their hair. There is an increasing trend of leukemia caused by hair dyes, so the medical community has specifically named it hair dye leukemia to alert people to it.

There are also reports in Chinese medical journals about hair dyes causing leukemia, skin cancer, and bladder cancer. Harbin No. 1 Hospital admitted 6 patients (5 women and 1 man) who developed leukemia due to frequent hair dyeing; the Hematology Department of 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 contains 5 to 10 times the amount of lead in household paints and pigments. Once lead enters the human body, it is difficult to be excreted, causing cumulative poisoning, resulting in a series of lead poisoning symptoms such as dizziness, headache, fatigue, numbness of the limbs, cramping pain in the calves, abdominal pain, etc. It also enters the liver, kidneys and brain marrow, destroying the functions of these organs. In severe cases, lead can cause loss of labor.

From the above understanding, we can know that hair dyeing is extremely harmful to people. The large amount of chemicals contained in hair dyes are not only harmful to people's hair but can even cause some serious diseases. Although loving beauty is a natural thing, we should still pay attention to our physical health while loving beauty, which is the most important thing.
