Beauty hair is not only the need of women but also of men. Especially at the end of the new year to spring, everyone wants to 'refurbish' beauty, refresh their hair. But for health reasons, please wait if you choose to dye your hair permanently.
A new study based on more than 46,000 women by US scientists published in the International Journal of Cancer shows that perpetual hair dye chemicals increase the risk of breast cancer.
Permanent hair dye simply means using chemicals to oxidize natural hair color. Normal hair dyes will lose their color over time, and hair will return to its true color in a short time. Then permanent hair dye will change the chemical structure of the hair, by using amino aromatic and phenol, reacting with hydrogen proxide and ammonia, or MEA - monothanolamine.

Permanent hair straighteners also use chemicals to "squeeze" the hair into the fold. New hair colors and folds will last until the new hair grows.
Research results show that women who use permanent hair dye are about 9% more likely to develop breast cancer than other women. 55% of women surveyed said they have used permanent hair dye in the past 12 months.
The author of the report Alexandra White - a scientist at the American Academy of Environmental Health Sciences - said that people who dyed their hair at least once a year had a 45% higher risk of breast cancer than women who did not. Hair dye. People who dye their hair regularly (every 5 to 8 weeks dyeing) are 60% more likely to develop breast cancer.
According to Alexandra White, in chemicals for permanent hair dyeing and straightening contains formaldehyde, a compound that causes cancer. These chemicals stick to the hair, potentially disrupting the chemical structure of the hair shaft, which can enter the bloodstream, circulate in the body and to breast tissue.
There have also been studies that show that hair stylists who are exposed to dyes and other hair chemicals are at high risk of cancer.
Dr. Larry Norton - at Memorial Sloan Kettering Cancer Center in New York (USA) - said that the research data is very small, low risk so it is not worrying.
However, some scientists believe that a small percentage of cancer risk does not mean that these products are safe, because regular beauty is now very common. These chemicals are also circulating in every country in the world. Most products on the market today have not been fully tested for safety and they have not been tested for endocrine disrupting chemicals.
