My dad used to tell this tale about my brother Jerry, who, at age five,would watch Dad shave and put on hair oil. He liked the fragrant goo the barber put on him at the shop, too. So one day, he climbed up to the medicine cabinet and found some kind of liquid to put in his hair and Dad found him dancing and howling. Turned out it was Sloan’s Liniment, probably 100% alcohol, plus some other irritants like menthol; good for ankle sprains but not for the scalp.
