Thing is, back in the day, both in the Roman Empire and throughout western history, short hair was for soldiers! Indeed, the military crewcut still reflects that. It was and is practical in such a profession, and among Romans, the aristocracy was expected to be, at least nominally (and usually outright) military. In medieval and Renaissance Europe, same thing, and courtiers and scholars grew their hair long partly to show that they were
not members of the martial class.
I wouldn’t think hairstyle has anything to do with one’s faith, unless one takes a tonsure as a religious (Christian, Buddhist, etc) or keeps the long sidelocks if one is an Orthodox Jew, and so on. Even worrying about ‘calling attention to one’s self’ by having a colorful mohawk or dreads and suchlike need not be an issue - some of us would stand out among our friends if we did NOT have such a do, although that’s no reason to wear your hair that way, or ANY way either.
I don’t think Jesus would give a rip about your hair. All over the world, people wear their hair all kinds of amazingly nifty ways - it’s something we can have fun with and express ourselves! Enjoy that shining glory! One of my few regrets in life is that I didn’t do more crazy and fun stuff with my hair when I was young, and I did have a 'hawk for a while.

I may very well dye my hair violet this winter, just because I like the idea. Okay, maybe not dignified for an old prematurely-greyhead like myself, but it’d make me feel comfortable somehow.
