I'm not an expert in vintage hairstyling, but I understand that Betty gets a wash and set styling at the salon, probably one a week, like many affluent women of this era did. My understanding is that in order to maintain that look throughout the week, you'd have to wear foam rollers or pin curls under a bonnet to sleep in. However, we always see Betty with her hair straight and natural at night, meaning she must somehow do her hair in the mornings. This is before modern hair tools like curling irons.

Mad Men seems to generally have an almost obsessive attention to historical accuracy, so I'm curious about this apparent oversight.
