We’re so quick to say, “It’s assur because it’s like goyim!” but, if we couldn’t do anything they do, we’d be in trouble.
“Nope, you can’t go to Walmart, goyim do that!” and, “It’s assur to eat popcorn! That’s goyish!” “Are you driving a car?! That’s a goyish influence!”
Maybe having bangs is assur, maybe it’s not, but I’m personally sick of hearing that things are ‘Goyish’. There’s nothing ‘Goyish’ about things that aren’t Jewish. They might not be in accordance with minhagim or religious standards we hold as frum Jews, but that doesn’t make something ‘Goyish’. It makes it secular.
And for the most part, there’s nothing wrong with secular things. We involve ourselves with things that aren’t necessarily Jewish for most of our days. And that’s okay, as long as we understand that those things aren’t our priority.
So as long as your haircut isn’t a halachic problem, go ahead and do what makes you happy. I personally think long hair on men looks terrific, if you can pull off the look.
Good luck
