I had heard of using ice before, but not peanut butter. It certainly wouldn’t cause any harm to use peanut butter. I once, back in junior high school, got a drill bit caught in my hair, I was lucky I didn’t kill myself with the damned thing, it sucked my head all the way in. No amount of peanut butter or ice was going to help that situation. I had to cut out the whole chunk of hair. Oh, the folly of youth an vanity, what a dreadful combination.
