Red Hulk doesn't have a mustache. But as seen in this answer, he has a mustache in mere-mortal mode. Why? Doesn't "Hulking out" scale up your normal body? Is he using a mustache-wig in normal mode?

Yes, I know that I'm writing about a character that violates mass/energy conservation but only complaining about him also violating hair conservation.

    Out of canon, the answer is probably because the identity of Red Hulk was a secret for months before his true identity was revealed.

  • The gamma transformation seems to have a sort of template for what the final product is regardless of what the person looks like in their "calm" state. It's that sort of cromagnon brow, shaggy dark hair, no neck, big hands and feet look. Although didn't Banner shave his head and that translated in to a bald Hulk once?

    I agree with @krillgar - the actual answer from a writing standpoint is that the mustache would have made guessing his identity too easy. As far as I know, only one character has that particular kind of mustache. Sorry, make that two (Dum-Dum Dugan being the other).

Well, his hair and nail color also seem to change, along with his skin color and complexion/size (of course!). He doesn't seem to have hair on arms, chest or legs (and I don't want to find what is under the indestructible pants), so maybe this "hair recessing mystery" is just part of the Hulk transformation process' magic altogether.

If we suspend the disbelief for the "mass/energy conservation" process, could be safe to do so for the "hair conservation".

    I felt that 'indestructible pants' needed a TV tropes link :-)

This explains it.


Human hair is a simple thing made of keratin and [b]dead skin cells[/b].


Are hair and fingernails considered "living" tissue or matter biologically?

Except for the roots, they're dead.

As these cells are already dead when he powers up he loses it. During Aaron's Incredible Hulk run, Hulk took a gamma bomb at point blank range and lost all his hair - as the cells are dead they didn't regenerate.
