Hair colors – Ingredients
To ensure that hair dyes cover gray hair reliably and can not be washed, strong chemicals are needed.
The problematic components include, for example, aromatic amines. These include substances such as 2,5-tolendeniamine (PTD), phenylenediamine (PPD) and hydroxyethylphenylindeniamine. All three are strong sensors. Two other aromatic amines are 6-amino-m-cresol and 5-amino-6-chloro-o-cresol. For both, it is still unclear if they are harmless. However, they are used in hair colors.
Other aromatic amines are p-aminophenol. It is considered a baby and a cancer and should be able to reduce fertility. In fact, it is blocked in cosmetics. However, manufacturers may obtain an exception if the material does not exceed a certain amount in the product.
Many hair colors also contain resorcinol, which irritates the skin, causes allergies to allergies and can also irritate. In addition, the usual hair colors can be found in traditional cosmetics such as PEG / PEG derivatives (make Trialix the skin permeable to contaminants), organic halogenated compounds, doubtful ultraviolet filter and fragrance allergens (ZB lyral, which also found in Many fragrances can cause allergies)
The risk of developing bladder cancer is double the monthly hair dye
Previous studies have shown that hairdressers have a higher than average risk of developing bladder cancer. The first study on this topic was published in February 2001 in the International Journal of Cancer.
The researchers at the University of California at Los Angeles had 1,514 people with bladder cancer and had the same number of people of the same age who were healthy. Women who shed their hair at least once a month were twice as likely to develop bladder cancer as those who did not get their hair stained.
If you dye your hair in the long term, for many years, the risks will continue to increase. For example, if you apply hair color every month for 15 years or more, the risk of injury increases 3.3 times. Stylists who had worked in their profession for at least 10 years were five times more likely to develop bladder cancer than those who did not use hair dyes.
The risk of cancer can not be ruled out by hair coloring despite the list of prohibitions
Subsequently, in 2003, the European Commission issued a list of bans for almost 200 of the most dangerous substances that were present in hair dyes at that time. The list of classified substances is safe (with some limitations) trialix Canada for hair coloring, there are only 70 left. But even for these, it can not be conclusively said that they do not represent the risk of cancer for humans. Even if they do not cause cancer, they are not healthy at all, since many are considered strong allergens, for example. For example, p-phenylenediamine and 2,5-toluenediamine.
