Somehow he acquired a time machine. I'll have to go back and read it to remember the details.
He had to make sure to shave and cut his hair and fingernails before he went home because he had no way to do so with his invulnerability. His hair and nails didn't grow when he had his powers. I guess before that he had been stuck with whatever haircut Lara had given him on Krypton before she sent him to Earth.
