5. Nicol Williamson, "How to Dial a Murder" (Originally aired April 15, 1978) Though this Shakespearean stage star's blond locks were receding up top, he kept them flowingly long on the side, in a nest of well-honed curls and waves.

4. Ruth Gordon, "Try and Catch Me" (November 21, 1977) Miss Gordon keeps her hair swirled around and piled on top of her head, as befits an 81-year-old woman. (She's the oldest killer in any episode of "Columbo.") The dye job is so subtle that I noticed it only fleetingly in one scene, but what places her on this list is when she lets the whole thing pile down in a long pigtail that dangles down her back, turning Miss Gordon into the world's only 81-year-old pixie.
3. Johnny Cash, "Swan Song" (March 3, 1974) Jet-black, shaggy, freed from its AquaNet cage, Cash's hair reaches its own pinnacle in this episode.

2. Robert Vaughn, "Troubled Waters" (February 9, 1975) Vaughn's hair is legendarily perfect, but what makes it remarkable in this episode - the one on the cruise ship - is that it was actually shot on board the Sun Princess. So every time Vaughn stepped outside, the wind blew his hair every which way, but by the time he came back inside, every single strand had fallen back into its proper place. It's amazing to see a head of hair with its own character arc.
1. John Cassavetes, "Etude in Black" (September 17, 1972) Cassavetes' cascading Greek curls beautifully fit his character, a philandering (and murderous, natch) conductor: artistic, louche, sophisticated.
