Coloring or straightening hair has gained massive popularity in recent years. The two standard beauty-care products have become a trend or the hottest sensation among people, particularly women. But note that such fashion can harm the body. A new study, published in the International Journal of Cancer, on Tuesday, reveals the devastating fact. Besides, scientists concern ladies who apply permanent hair color or chemical straighteners are at a higher risk of breast cancer. Researchers from the National Institutes of Health have conducted a clinical trial on around 50,000 women for up to eight years.
The team has discovered that the chemicals present in both beauty products may raise the probability of breast cancer. Notably, women who had notified a regular use of permanent hair dye had a 9% greater risk of developing the disease. Besides, women who had used chemical un-curler in every 5-8 weeks, had a 30% more chance. While scientists have cautioned chemicals can enter into the skin and eventually body through the scalp. Sometimes, the vapors might enter into the body through breath, when users are applying it. Thus scientists say staying away from these chemicals might be a way to lessen the risk of breast cancer.
On the other hand, the National Cancer Institute claims there are more than 5,000 chemicals used in hair dye products. Even more, some trials have revealed these chemicals are carcinogenic for animals. Still, it is unclear which use of which compounds in those cosmetics can directly lead to cancer in humans. There exist some proofs, which are mystifying. Alexandra White, Ph. D., head of the NIEHS Environment and Cancer Epidemiology Group, is one of the corresponding authors of the study. She said, in the trial, they have noticed an excessive risk of breast cancer linked with the use of hair dye. Alexandra also noted they had seen a more powerful impact on frequent users, mainly African American females. According to the CDC, breast cancer is the most common type of cancer in American women after skin cancer.
