I'm still searching for a suitable pair. Lol. I'll check Walmart next time I'm there.

Would you explain your answer for those that haven't worked it out.

First, Superman's hair can NOT grow in Earth's atmosphere, so as long as he is here there is never a need to cut it. Secondly, any attempt to cut Superman's hair by ordinary means results only in the shattering of whatever scissors are being used, but Superman can cut his own hair when absolutely necessary by subjecting it to the concentrated power of his own X-ray vision. In a red-sun environment, however, where Superman has no super-powers, his hair loses its indestructibility and begins to grow. If Superman undertakes a mission to a red-sun Planet, it is best for him to shave and trim his hair before returning to the yellow-sun environment of Earth, where his hair will once again become indestructible.
