New Study: Women who paint hair at home are not endangered by cancer

The cases that paint their hair at home are unlikely to increase the chances of being affected by cancer, according to the findings of a recently published new study.

Researchers have tried to find a possible link between hair dye products and certain types of cancer for years, but although the World Health Organization's research agency has classified the products of hair dye as potentially dangerous products, it has provided no warning about products used at home.

The latest study was published in the BMJ medical journal, and data was collected by 117,200 nurses in Brigham and Women's Hospital in Boston. Women did not have cancer at the start of the study and were followed for 36 years.

The results showed no increase in cancer risk or cancer deaths in women who reportedly used permanent hair - painting products compared with women who did not use such products. The study found that using hair does not increase the risk of bladder cancer, brain cancer, colon, kidneys, lungs, skin cancer, and breast cancer.

The most aggressive animals are the permafrost species (burning in hair until the hair grows and exposes the natural root), which account for approximately 80% of hair paints used in the U.S., Europe and Asia. Hair coloring is estimated to be used by 50% to 80% of women and 10% of men aged 40 and more in the United States and Europe, according to the study.

The authors highlighted certain restrictions in the study, including the lack of racial diversity among participants, as mainly American white women of European descent were involved. They added that other factors, such as the use of other products, may have affected results.
