Very occasionally, I go to the Dominicana salon for a blow job. I always preface it by pointing out the obvious: that I am a gringa, and I am also very tender-headed. And then the lady revs up the blower to flame-thrower and starts yanking my hair with the round brush until I can feel my scalp popping. There is ALWAYS a moment when I have to take a break. I cannot imagine submitting myself to this torture on a regular basis.
Coincidentally, I once brought in this spray I have to keep the few curls I have in my hair, and wanted it dried with a diffuser. The young girl was horrified, because who wants "bad" hair, and she had no idea how to use the diffuser until Clary showed her.
