I had a sister that did the whole ratting and hairspray. She also bleached her hair into a very, very pale ashy white.
It's probably a good thing she kept it shorter than 4" at its longest part.
Remember all the scary stories about black widows nests, starting yourself on fire, or actual rats living in hair ratted beehive hairdo's?
By the time I became a teen, all I wanted was sleek, long, center parted hair. Alas, it was never to be.
