All kinds of hair dyes contain dozens of chemical ingredients, and according to the testing of more than 100 kinds of hair dyes by the relevant departments, nearly 90% of hair dyes contain toxic chemicals such as nitrobenzene and aniline, which are easily absorbed by the skin and are harmful to the human body. If long-term use of hair dyes, as long as 1% is absorbed by the skin into the body, it will accumulate poisoning, in which chemicals combined with certain cells, damage to the nucleus of the deoxyribonucleic acid, causing cell mutations, and induce skin cancer, bladder cancer, leukemia, etc., experts cautioned against this “disease from the hair into”.
The American Cancer Society study showed that women using hair dyes have a 70 percent increased chance of developing lymphoma. A survey of 13,000 women with dyed hair found that the number of leukemia they suffered was 3.8 times higher than that of women without dyed hair. There is a growing trend of hair dye causing leukemia, and the medical community has taken the name hair dye leukemia to alert people.
Some imported hair dyes also contain lead acetate, which contains 5-10 times more lead than household paints and pigments. When lead enters the human body, it is difficult to be excreted and causes accumulation of poisoning, dizziness, headache, tiredness, numbness of the limbs, spasmodic pain in the legs, abdominal pain and a series of lead poisoning symptoms, and enters the liver, kidneys and brain marrow, destroying the function of these organs and causing loss of labor in serious cases.
I advise you to enhance self-protection awareness less hair dyeing for beauty should also weigh the pros and cons, not to damage their health, especially those with allergies, blood disease patients should not dye their hair, pregnant women and lactating women should not dye their hair, so as not to endanger the next generation.
