Sometimes we don't see Jennifer Davis for weeks at a time -- she's a general-assignment reporter, not an anchor-twit, so her schedule's not fixed -- and even though we know she's probably off on some girl-reporter-type adventure, we often find ourselves worrying that she's been whisked away by the Newscaster Hair Patrol to await trial on charges of excessive brunettism. Against the Malibu Barbie backdrop that is local TV news, Davis' cheeky dark-auburn bob borders on subversive. With its rakish side part and faint wave, the jaw-length do has a definite noirish appeal: Check out Davis in the middle of a cornfield, fresh on the trail of some rural mischief, her wayward russet strands aloft in the windy night. (That's right: Davis' hair actually moves.) Whereas most of her peers sport hairstyles that are relentlessly tasteful -- or, in the case of the WB anchorettes, borderline slutty -- Davis' hair is sensible without being frumpy, sexy without seeming high-maintenance. One part Myrna Loy, one part Brenda Starr, Davis has a brisk, understated glamour that's sorely lacking in today's local TV-news market. She's got the kind of hair that looks as if it belongs in a Raymond Chandler novel, the kind of hair that seems to say, all snappy-like, "Hey, sister. Spill the beans! I haven't got all day!"
