Oct. 20, 2022 – Clarissa Ghazi will get lye relaxers, which include the chemical sodium hydroxide, utilized to her hair two to a few instances a yr.
A latest examine that made headlines over a possible hyperlink between hair straighteners and uterine most cancers will not be going to make her cease.
“This examine will not be sufficient to trigger me to say I am going to keep away from this as a result of [the researchers] don’t show that utilizing relaxers causes most cancers,” Ghazi says.
Certainly, main care docs are unlikely to handle the elevated threat of uterine most cancers in ladies who incessantly use hair straighteners that the examine reported.
Amongst frequent customers of hair straighteners — that means those that used them greater than 4 instances a yr — the researchers discovered that ladies have been 2.55 instances extra prone to be recognized with uterine most cancers than those that by no means used these merchandise.
Within the just lately printed paper on this analysis, the authors say that they discovered an 80% increased adjusted threat of uterine most cancers amongst ladies who had ever “straightened,” “relaxed,” or used “hair urgent merchandise” within the 12 months earlier than enrolling of their examine.
This discovering is “actual, however small,” says internist Douglas S. Paauw, MD, professor of medication on the College of Washington in Seattle.
Paauwis amongst a number of main care docs interviewed for this story who expressed little concern in regards to the implications of this analysis for his or her sufferers.
“Since we’ve tons of of issues we’re supposed to debate at our 20-minute clinic visits, this is able to not make the minimize,” Paauw says.
Whereas it’s good to have the ability to reply questions a affected person may ask about this new analysis, the examine doesn’t show something, he says.
Internist Alan Nelson, MD, an internist-endocrinologist and former particular advisor to the CEO of the American Faculty of Physicians, says whereas the examine is nicely performed, the variety of precise instances of uterine most cancers discovered have been small.
One of many causes he wouldn’t suggest discussing the examine with sufferers is that the manufacturers of hair merchandise used to straighten hair within the examine weren’t recognized.
Alexandra White, PhD, lead creator of the examine, mentioned individuals have been merely requested, “Prior to now 12 months, how incessantly have you ever or another person straightened or relaxed your hair, or used hair urgent merchandise?”
The phrases “straightened,” “relaxed,” and “hair urgent merchandise” weren’t outlined, and “some ladies might have interpreted the time period ‘urgent merchandise’ to imply non-chemical merchandise” comparable to flat irons, says White, who can also be head of the Nationwide Institute of Environmental Well being Sciences’ Setting and Most cancers Epidemiology group, in an e mail.
Dermatologist Crystal Aguh, MD, affiliate professor of dermatology at Johns Hopkins College of Drugs, tweeted the next recommendation in gentle of the brand new findings: “The general threat of uterine most cancers is kind of low so it is essential to keep in mind that. For now, if you wish to change your routine, there isn’t any draw back to lowering your frequency of hair straightening to each 12 weeks or extra, as that will reduce your threat.”
She additionally famous that “types like relaxer, silk urgent and keratin therapies ought to solely be performed by an expert, as this can lower the probability of hair injury and scalp irritation.”
“I additionally encourage ladies to search for hair merchandise freed from parabens and phthalates (that are generically listed as “perfume”) on merchandise to reduce publicity to hormone disrupting chemical compounds.”
Not Able to Go Curly
Ghazi says she determined to cease utilizing keratin straighteners years in the past after she discovered they’re made with a number of added elements. That features the chemical formaldehyde, a recognized carcinogen, in keeping with the American Most cancers Society.
“Individuals have been enjoyable their hair for a really very long time, and I really feel extra snug utilizing [a relaxer] to straighten my hair than any of the others on the market,” Ghazi says.
Janaki Ram, who has had her hair chemically straightened a number of instances, says the findings haven’t made her frightened that straightening will trigger her to get uterine most cancers particularly, however that they’re a reminder that the chemical compounds in these merchandise might hurt her in another approach.
She says the brand new examine findings, her data of the injury straightening causes to hair, and the prolonged period of time receiving a keratin therapy takes will lead her to cut back the frequency with which she will get her straightened.
“Going ahead, I’ll have this performed annually as a substitute of twice a yr,” she says.
White, the creator of the examine, says in an interview that the takeaway for customers is that ladies who reported frequent use of hair straighteners/relaxers and urgent merchandise have been over twice as prone to go on to develop uterine most cancers in comparison with ladies who reported no use of those merchandise within the earlier yr.
“Nevertheless, uterine most cancers is comparatively uncommon, so these will increase in dangers are small,” she says. “Much less frequent use of those merchandise was not as strongly related to threat, suggesting that lowering use could also be an choice to cut back dangerous publicity. Black ladies have been probably the most frequent customers of those merchandise and subsequently these findings are extra related for Black ladies.”
“We estimated that 1.64% of girls who by no means used hair straighteners would go on to develop uterine most cancers by the age of 70; however for frequent customers, that threat goes as much as 4.05%,” White says in a assertion.
“One of many unique goals of the examine was to higher perceive the environmental and genetic causes of breast most cancers, however we’re additionally serious about learning ovarian most cancers, uterine most cancers, and plenty of different cancers and power illnesses,” White says in an interview.
