Luthor's Hair, Or Lack Thereof

Lex Luthor shaves his head, right?

I know in the Silver Age, Lex famously lost his hair because Superboy zipped in to see him during some big experiment, disrupting everything and causing all his hair to fall out, but I doubt that's still in effect. Entirely too silly for current DC.

It just occurred to me that Lex is exactly the sort of person who would not want to be seen going bald, with thinning or receding hair. It would be a sign of weakness or imperfection, and Lex would probably feel that people with shaved heads are more respected than those with faltering hairlines (he'd probably conduct research to prove it).

But, this is Luthor we're talking about. Surely he could devise something that would restore his hair. Which leads to a few conclusions in my mind. One, Lex has been too distracted with destroying Superman. Eh, I can't see the hair thing being that time-consuming to Lex. Two, he actually prefers being shaved, thinks it makes him look sleek and aggressive. Three, he has developed it, but chooses not to use it, because he doesn't want anyone to know he did. Because if that becomes common knowledge, people will think he used it, and Luthor wouldn't want his vanity and ego to be so apparent as a sign of weakness. Lex wouldn't admit it as such, he'd decide he was holding it back because the masses didn't deserve it or something. Let them ask their Superman to restore their hair.
