Kevin Nealon ABSOLUTELY wears. He had transplants years ago, the results were not good. They certainly didn't give him anything close to the coverage he has now.

He's been wearing for years -- I think it's very obvious for those who know what to look for. Howard Stern used to give Nealon shit for wearing a wig (not sure why he gave a shit about KN, but I have a clear memory of this). For sure, though, KN's pieces have improved from the first ones he wore.
