I went to college with a girl that had very thick, curly, thigh length hair. She would wash it, then section it off and wrap it around her head and pin it in an effort to straighten it. She then would put her hair dryer (the kind with the big plastic bubble looking thing that fit over your head) on and sleep with it running all night. The hose was secured with duct tape to make sure it didn't pull out. Maybe the hairdryer one was for her. LOL
