Quote: One of Lex Luthor's identifying characteristics is the fact that he's bald, but he wasn't always. So how did Lex Luthor lose his hair in the first place? Well, there are a few reasons in the comics as to why this happened that range from natural hair loss to more exciting backstories involving his hair being burned off. But the first time Luthor appeared bald in a comic was not an intentional choice, but a complete accident! Today we're learning about all the reasons in and out of comics as to how Lex Luthor became bald.
My memory of the cause of Lex's baldness was the Super Friends episode which was a take on an earlier Superboy comic book flashback where Superboy caused Lex's baldness while trying to put out chemicals. Shown in the video above.
