If 80% of the population in a community has one hair type, every hairdresser will learn how to dress that type of hair. Not every hairdresser will learn to dress the various types that make up the other 20%. This is especially true if the 80% group has more money than the 20% group.

The products that will straighten hair and that will dye hair dark colors are extremely toxic. All women are under strong pressure not to have gray hair and women with curly ethnic hair are under extreme pressure to straighten it to be seen as attractive and professional. This is still true, but was even more true in the past.

I’m not trying to be difficult but I don’t really want to answer that in a public forum. Never know how the data is being collected and used. Maybe just give a dual response for if I was and if I wasn’t?

Maybe it’s different for different groups but I have never in my life requested or even thought to request a barber that is my specific race. I feel like it’s mostly ever been barbers who aren’t my race actually, they seem to give me what I’m looking for either way

Ethylmethacrylate (glue for acrylic nails) is the main culprit. That stuff reeks as well. I have personally experienced building up a tolerance to a smell but it's so pungent that you should always detect some amount of it.
