Elvis admitted that what we called back then, if I remember correctly, "the Tony Curtis roll" was what he was going for in his hairstyle that went on to influence even more young males. But it was Curtis who started the trend.
No self-respecting juvenile delinquent ("j.d." was the common term) or wannabe "j.d." would want to be seen without that little twist of hair right above the middle of your forehead, which dramatically contrasted with the slicked back or "greasy" long (for the times) side hair that gave rise to the term "greasers" etc.
It may seem trivial to focus on the hairstyle of a man who was a Hollywood legend, as they say, and despite the guffaws at his Bronx accent in Roman epics (SPARTACUS et. al.) was in fact a terrific movie star actor who played an incredibly wide range of characters for one who was known mostly as a pretty face at the time.
But for men of a certain era, it was all about the hair, getting just the right twist in front and amount of grease to slick back the sides so that even a punch in the jaw wouldn't jar it. And no matter how much critics or more sophisticated adults made fun of the man, he was a hero, a role model, a class statement saying, like it or not I'm cooler than anyone looking down their nose at me, and we all knew it.
Here's the evolution of "the roll" (or as we'd say to the barbder in our little tough guy voice "gimme a Tony Curtis"):
