thanks to very helpful reader responses:
* They are not just in Chicago. HQMs thrive in New York City (but only midtown Manhattan and not Brooklyn) and living specimens have also been discovered in Washington D.C., Boulder, Colorado, and as far west as Malibu, California. Many have also been found in Toronto, so when it comes to customs regulations I guess they’re not inspected as thoroughly as produce or domestic animals.
* According to the anecdotal evidence so far, the salon services include brow waxing, “paraffin hand dipping,” occasional use of illegal Russian hair dye, and really crappy haircuts.
* There are also Hair Question Women. However, there is little to indicate that Hair Questioners reproduce sexually. My theory is they release airborne spores called “product.”
* Also: Nail Question Men. Possibly a mutation of the species. And I don’t know about you but “Can I ask you a question about your nails?” sounds like it would be even creepier coming from a complete stranger.
