Seeing that New Year's Day is coming, the New Year's Festival, it is impossible to avoid visiting relatives, and naturally people will also pay attention to their external image.
Therefore, hair coloring is called an important way for people to welcome holidays. Hair coloring is already commonplace for men and women in today's society.
Dyeing hair into a variety of colors can not only appear more trendy, but also enhance the color and appearance, even the elderly find that after the hair turns white, they often cover their white hair by dyeing their hair to make themselves look younger.
However, there are also some people who believe that hair dyes contain a lot of chemicals, and if frequent hair dyeing will cause the skin tissue of the head to be stimulated by chemicals, increasing the risk of carcinogenesis, is this true?
Regular hair coloring does increase the incidence of cancer.
In particular, there are a variety of hair dyes on the market, among which there are nearly ten chemicals in an oxidized hair dye, which may cause mutations in the body's cells.
If hair is frequently dyed, these harmful substances will cause irritation to the skin of the scalp and enter the human body, causing the body's cells to be stimulated and damaged, and the risk of mutations in cell tissues will be greatly increased.
According to clinical research, about 40% of women suffer from leukemia because of frequent hair coloring, especially the number of middle-aged and elderly patients with acute leukemia is higher.
In addition, regular hair coloring may also cause people to suffer from skin cancer, breast cancer, bladder cancer and so on.
Although hair coloring will increase the risk of cancer, if you can do the following three aspects, you can also rest assured that you can dye your hair.
First, pay attention to washing your hair before and after hair coloring
Want to reduce the damage caused by hair dyeing to the body, in the first three days of hair coloring, we must try to avoid shampooing, so that the scalp environment is in a dry state, in the 4-6 hours of dyeing hair, hair dye has been completely dried after you can wash your hair again, you can reduce scalp allergic reactions, so that the scalp is stimulated to reduce, is conducive to reducing the risk of carcinogenesis.
It is worth mentioning that after dyeing the hair, it is necessary to keep the scalp clean, you can appropriately reduce the interval between washing the hair, wash off the residual hair dye of the scalp by frequently washing the hair, avoid excessive hot water temperature when washing the hair, and can not scratch the scalp hard, so as not to scratch the scalp after it is scratched, resulting in harmful substances entering the skin tissue and causing more damage to the body.
Hair should not be colored repeatedly for two or three months
Most hair dyes have a certain amount of decolorant in them, which can cause some damage to the hair scales of the hair.
If the hair is frequently colored, it will make the hair easier to split and break off, not only that, but also lead to repeated stimulation of the scalp, a large number of harmful substances through the hair follicle into the skin after damaging normal cell tissue, so that the body is invaded by cancer.
Third, do not use sexual hair dye
Ninety percent of the hair dyes on the market contain harmful chemicals such as aniline and nitrobenzene, which will cause violations of cell tissues and increase the risk of cancer after entering the human body. Therefore, when we dye our hair, we should choose some hair dyes that are less harmful.
If there is decolorization within one to two days of hair coloring, it is mostly a semi-sexual hair dye.
If it takes two weeks to start decolorization, or no decolorization at all, it may be a sexual hair dye, which is more harmful to the human body, and it is necessary to be vigilant and try to avoid the use of this sexual hair dye.
In summary, regular hair coloring does increase the risk of cancer. If you want to dye your hair with confidence, you should pay attention to the above three aspects, as far as possible to reduce the stimulation of the scalp, and the number of hair coloring is best controlled within three times a year.
If you want to maintain the effect of hair coloring, it is recommended that you directly re-dye the newly grown parts and do not change the color of your hair frequently.
