Don't take this literally

This is just a stupid, ridiculous question

So feel free to answer this as ridiculous as possible.

Folks, I've seen Supe's hair and I wanted to know if Superman has

Straight hair or curly hair

Tell me what you think?

I feel like older comics make it seem he has curly, while never ones give him straight.

Curly hair

Well, I prefer it straight, but there are gay rights and all.

lol

Maybe slightly wavy? I think he exaggerates it a bit depending on if he is Superman or Clark, so it's a little hard to figure out what is completely natural.

Straight, but put a (clean, kept) beard on him.

I would say it's wavy rather than curly, and as Clark I think it should be either messy or straight(combed properly) for secret identity purposes.

Usually it is a straight hair with a single famous curl, but often enough (and I prefer this variant) Superman has a wavy hair. It either messy in Super-mode and combed in everyday life or other way around (New-52 IMO).

I always saw it as a little but curly, like Henry Cavill's hair in Man of Steel.

Slightly curly hair.
I mean the "S" curl pretty much sums it up.

Straight

Sadly that's been ruined by New 52
