Rare and aggressive uterine tumors are rare. Rapidly risingA new study has suggested that chemical straighteners may be partially to blame for the increase in hair loss in the United States, particularly among people of color.
The US National Institute of Environmental Health Sciences’ (NIEHS), tracked 33,947 women who were pregnant at the time of enrollment. This has been going on for nearly 11 years. Over this period, 378 uterine samples were collected. CancerThese cases were identified.
Researchers found that those who had used a chemical hair straightener product at least four times in the last 12 months were 155% more likely to develop uterine carcinoma. This was in comparison to those who had not used any such products.
This means that those who don’t use hair straighteners have a 1.64% chance of getting uterine carcinoma by their 70th anniversary. That number creeps up to 4.05 percent among those who frequently straighten their hair chemically – a still small, but appreciably higher risk.
Hair dyes were not associated with uterine cancer.
Researchers at NIEHS claim that these findings provide the first epidemiologic evidence linking straightening products to uterine cancer. Send an email.
These alarming results result from recent research on chemicals that disrupt the hormone system. They are messenger chemicals, which connect hormones with their target organs.
In the past, excessive hormones such as estrogen and progesterone were linked to uterine cancer. Many hair products are also known to cause uterine cancer. These natural hormones can be mimickedThese receptors are bound to them.
2018 was a year of research Find itThere were 18 hair products that tested positive for endocrine disrupting chemicals. Furthermore, 84 percent were not listed on the product labels and 11 products contained chemicals that are prohibited by the Cosmetics Directive of the European Union or regulated under California law.
Federal regulations in the US currently require testing for estrogen receptor activation Only when it comes to pesticides or drinking water contaminants. This could lead to serious health problems for the public.
2019: StudyResearch funded by the NIH showed that permanent hair dyes and straightening chemicals were associated with a higher incidence of breast cancer among women of color, particularly those who receive them more often.
A follow-up will be held in 2021 StudyResearchers also found that permanent hair dyes and straightening chemicals can increase the risk of developing ovarian cancer.
You can add uterine cancer to that list. Although the study of this new type of cancer did no identify any differences between racial or ethnic groups, the authors noted that Black women may use more straightening products at earlier ages and in higher amounts. One StudyIt was found that 99% of African American women used chemical relaxers or hair straighteners.
The NIH is still trying to determine which chemicals in hair products could cause carcinogenic effects. However, parabens and formaldehydes are the most likely suspects.
The human scalp can absorb chemicals that may not be made through thicker skin or those with fewer hair shafts. Hot ironing or blow drying can thermally decompose chemicals on hair, which could lead to even more dangerous results.
“We observed stronger associations between straightener usage among women with low levels of physical activity,” said the authors. Send an email.
Women who are more active might be more likely to develop uterine cancer due to the association between physical activity and sex hormones. More research is needed to determine the relationship between physical activity and hair product use and uterine cancer.
Roughly The US has half of all womenSome people have used permanent hair dye. However, smoothing keratin treatments or Brazilian blowouts are increasingly popular.
The products have a negative impact on hairdressers’ health and the clients of their salons.
The study was published by the Journal of the National Cancer Institute.
