Xiao Li and Xiao Hui are roommates in the bunk beds of the university. They have a common hobby, chasing stars. Because their favorite idol recently dyed a very popular hair color, they thought about getting the same hair color as their idol, and they agreed to help each other dye their hair together, so they bought two boxes of cheap hair dye online. After dyeing, they are very satisfied with the result.

But after a week, Xiao Li and Xiao Hui developed rashes on their necks. I thought it was an allergy, so I bought some anti-allergy medicine, and it went away after eating it. But then he developed symptoms such as coughing and expectoration, and the medicine did not improve. After going to the hospital for a CT examination, he was told by the doctor that he had interstitial pneumonia.

Xiao Li’s condition was getting worse and worse, and she was so serious that she had to be put on a ventilator and eventually passed away unfortunately; while Xiao Hui experienced repeated aggravation and treatment for 6 months, although she was able to survive He died, but his lung function was severely damaged, and he relied on oxygen to maintain normal breathing.

The doctor said: They all used inferior hair dye!

This hair dye is mainly composed of 2 substances, namely dyeing agent and color developing agent. The main components of hair dyes are aromatic compounds, represented by phenylenediamine. After inhaling such substances, it is easy to induce hypersensitivity pneumonitis, which is a kind of interstitial pneumonia. Generally, it can be relieved by removing the sensitizing environment, but in severe cases. Can induce respiratory failure.

Also, after applying the hair dye, it will be heated and shaped. As the temperature increases, the harmful substances in the hair dye can follow into the lungs, especially the inferior hair dye. can directly cause lung damage. Thus, inferior hair dyes can lead to interstitial pneumonia.

Can hair dye cause cancer?

Because the phenylenediamine contained in hair dye is a recognized carcinogen, it has certain harm to the human body. Therefore, some people say that hair coloring can cause cancer.

The International Journal of Cancer has published an article showing that 46,709 women in the United States have been followed up for 8 years. Years of follow-up, the results were: 2794 women had breast cancer, and about 55% of the women had ever used permanent hair dye, so it was concluded that permanent hair dye May increase the risk of breast cancer.

But all talk of toxicity aside from dose is hooligan! It is unscientific to say that dyeing hair increases the risk of cancer.

Because cancer is caused by many factors, and hair coloring can cause cancer, it must be established on a certain dose. Regular hair dyes on the market need to be tested by relevant departments, and the chemical substances contained in them are controlled within the national standards. As long as you use hair dyes reasonably, you will not suffer from cancer .

Also, 2,794 women in this study developed breast cancer after using permanent hair dye, which is a theory that deserves further scrutiny. Because of differences in risk between different races, the development of cancer is complex and mysterious, and the subjects of this study were American women and everyone had Family history of breast cancer, and Chinese women, there is still no data to prove it, so we have to look at hair coloring and cancer from a dialectical perspective, and we cannot generalize.

What should I pay attention to when dyeing hair?

1. Choose qualified hair dyes

Inferior hair dyes contain too many chemicals, so As for the addition of numerous heavy metals and carcinogens, its quality cannot be guaranteed. Inferior hair dyes not only cause skin allergies, but also damage the internal organs and increase the risk of organ cancer. Therefore, hair dyes produced by regular manufacturers should be selected.

2. Control the frequency of coloring

The interval between coloring is at least half a year, even if you choose mild Hair dyes should also allow enough time between dyeing to avoid frequent dyeing.

Message from the doctor

Although dyed hair can highlight oneself personality, but with caution. When there is a wound on the scalp or a skin disease, the hair should not be dyed, so as to prevent harmful substances from entering the bloodstream from the wound, threatening the health of the body and increasing the risk of infection. After dyeing, as long as you have anyIf you feel unwell, you need to seek medical attention immediately, you can’t bear it.
