According to the abstract, samples were only taken from Black and Latina hairdressers, and compared to a sample of female office workers. So no White or Asian hairdressers were part of the study. But according to some of these comments, many people are overlooking that fact. So lots of the argumentative comments here don’t even apply. People are reading too much into this without checking the facts.

FYI I’m a white woman and get my hair chemically straightened as well.

I’d be interested to know if alternatives to typical sleep advice might be considered more, specifically for an insomniac with major depression/suicidal ideation. Personally have found the “turn everything off and just wait it out” type approach to be really bad for me. I still don’t sleep and my mental health gets much worse. Instead I’ve learned to do something that occupies and distracts my mind if possible (art or reading primarily) until my body finally just shuts down. It can take a long time but with depression, to me, it’s preferable. I just wonder if a more unique approach should be considered with all patients who have a specific combo of severe insomnia with mental illness.

Given their tech, i reckon their oral transmission was a tad more sophisticated than that. Assuming of course, that no extra terrestrial monoliths were involved.

Perms are a very common thing in Caucasian women once they hit their 60’s and their hair thins out - unless you want to look like a plucked bird. I suppose black women get their poisonous styling done earlier in life.

A single plastic product can leach up to 8700 different substances into the water. It totally depends on the materials in particular. Known toxins include bisphenol A (BPA) and PS oligomer, styrene monomer (SM), styrene dimer (SD) and styrene trimer (ST). Styrene is a suspected human carcinogen. Not all substances are yet even catalogarised. But its total toxicity is well known.

It’s still an active area of research, but quite possibly, yes. There are multiple chemicals involved that are being studied as endocrine disrupters and carcinogens. The background document at the link I posted goes into some detail.

The main chemical in perms, Ammonium thioglycolate, is also not great for you, but mostly functions as a strong irritant and sometimes allergen https://www.barbercosmo.ca.gov/forms_pubs/permwav_lfs11.pdf

Perhaps more importantly, though, perms are generally an option used for variety when they are in fashion. Even as a former fan of the perm, I haven’t had one since the ‘80s. Straighteners and relaxers have been treated as necessary for women of color with curly ethnic hair to be seen as professional and presentable. This means repeated regular use for decades.
