Long hair

Hello,
I plan on working in Cedar Point this summer. I am a male and I have long hair. My question is it allowed to have long hair if I keep it tied up at all times?

No long hair

idk, i knew a guy that had semi-long dreads last year all season in foods and no one ever said anything. I don't know if it is different because he was international but I know for certain his hair was longer than grooming standards

He might have gotten a religious exemption.

I am also an international student. My hope is that they may make an exception for non-representative position like laundry host or employee housing
