Can eating stained hair cause cancer?

Recently, some researchers have found through decades of research that the risk of hair dyeing causing cancer is really very small, or even not carcinogenic at all.

The risk of carcinogenesis such as p-phenylenediamine and hydrogen peroxide in hair dye is lower than that of smoke, alcoholic beverages, kimchi, betel nut, bacon, etc., and even lower than a large intake of coffee (coffee was once classified as a 2B carcinogen, but now it has been adjusted to level 3), so there is no need to be overly concerned.

Hair dyes are classified as Level 3 "substances that cannot be classified by the available evidence", not because they cannot be classified, but because there is no evidence of carcinogenesis in animals after extensive research, and there is no evidence that they cause cancer in humans, they are actually classified as substances that have little carcinogenic risk.

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.

This question seems to have been debated by everyone, people who think that it causes cancer is because hair dye contains possible carcinogenic ingredients, but can hair dye really cause cancer?

Does hair dye cause cancer? What are the dangers of dyeing your hair regularly, you will understand after reading it!

Hair perm contains lead, although it is carcinogenic, but it is not much, less than two to three times a year, as long as it is not long-term, frequent contact or not carcinogenic.

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 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, leukemia, etc.

Although according to current research, it is not possible to confirm a clear causal relationship between hair dye and carcinogenesis, a variety of hair dye product raw materials may have a certain sensitizing effect, and people with allergies need to pay attention. Until there are clear research conclusions, especially in the elderly and pregnant women, it is important to minimize the intake of potentially harmful substances.

Therefore, if you can dye your hair without dyeing, if you really want to dye your hair, you can do it once every six months at most.
