Hairdressers of color exposed to 'concerning' mix of unknown chemicals
Product use classes mapped to 13 detected compounds with median peak areas ≥2 in hairdressers in comparison with workplace staff. Credit score: Journal of Publicity Science & Environmental Epidemiology (2023). DOI: 10.1038/s41370-023-00519-z

Black and Hispanic hairdressers are uncovered to a fancy combination of chemical compounds, a lot of them unknown, doubtlessly hazardous, and undisclosed on product labels, Johns Hopkins College researchers discovered.

The brand new examine is the primary to use a sophisticated screening approach used to establish chemical compounds in meals and wastewater to evaluate chemical exposures in hairdressers. The outcomes, simply revealed within the Journal of Publicity Science and Environmental Epidemiology, recommend extra analysis is required to higher perceive the dangers for hairdressers, significantly these of shade, and the way finest to mitigate them.

“We all know girls are extra extremely uncovered to chemical compounds in private care merchandise and we additionally know girls of shade have elevated exposures in comparison with girls of different demographics,” stated co-author and principal investigator Lesliam Quirós-Alcalá, an assistant professor of Environmental Well being and Engineering who research chemical exposures’ well being results in underrepresented populations.

“We puzzled, what about girls who’re doing this as a career. How way more are they being uncovered. There actually wasn’t something on the market after we began this.”

Researchers examined urine samples from Black and Hispanic hairdressers in the USA and in contrast them to samples from girls of shade working in workplace jobs. Hairdressers of shade are suspected to have extra chemical exposures than stylists of different demographics due to the merchandise used and companies offered in salons serving primarily populations of shade.

In contrast to conventional research, the staff did not solely measure for chemical compounds anticipated to be present in folks working with hair merchandise, they appeared for different compounds that had not been beforehand investigated.

“The standard strategies simply search for chemical compounds we’d anticipate to be current, however these merchandise include lots of totally different chemical compounds and never all of them are identified,” stated senior writer Carsten Prasse, an assistant professor of environmental well being and engineering who research public and environmental well being impacts of chemical compounds within the setting.

“We needed to open up the lens and discover potential different chemical compounds that hairdressers is likely to be uncovered to in order that we may inform future laws of those chemical compounds.”

Utilizing the identical approach, the Prasse Lab present in 2022 that vaping aerosols include 1000’s of unknown chemical compounds and substances not disclosed by producers. These findings have been revealed in Chemical Analysis in Toxicology.

In comparison with the ladies working in places of work, hairstylists had greater ranges of chemical compounds of their our bodies related to salon remedies—hair relaxers, conditioners, dyes, and fragrances—but additionally many extra substances the researchers could not establish.

“There are extra chemical exposures on this occupation group than we anticipate,” stated lead writer Matthew N. Newmeyer, a postdoctoral fellow on the Johns Hopkins Bloomberg College of Public Well being.

Added Quirós-Alcalá, “It is positively regarding. Quite a lot of these chemical compounds we do not even know what well being dangers they could pose.”

There are greater than 700,000 hairdressers in the USA, greater than 90% of whom are estimated to be feminine, and 30% are Black or Hispanic/Latina. On this predominantly feminine workforce, with many ladies of reproductive age, exposures might not solely pose a girls’s well being subject, but additionally a youngsters’s well being subject as exposures throughout the preconception and prenatal interval may improve youngsters’s well being dangers, Quirós-Alcalá stated. About half the hairdressers on this examine reported working within the salon whereas pregnant.

The findings present extra research are important to higher perceive what hairdressers are uncovered to on the job, and to find out how finest to mitigate these dangers and to attempt to scale back any well being disparities, Prasse stated.

“It is clearly an below researched space,” he stated, “and there’s a racial dimension to it which should not be forgotten.”
