Bret Michaels is the lead singer of hair metal band Poison, he has also done some film and tv stuff.
Even back in the day, he was known for his assortment of bandanas. Apparently he even wore one for the duration of his sex tape with Pamela Anderson. I of course don't know anything about that.
He has claimed he uses hair extensions, but it looks more like a full blown hairpiece to me. This facebook page and the website http://bretswig.com/ seem to agree.
I find it interesting that he can admit to wearing extensions but not to suffering hair loss and wig wearing. This is still a taboo subject to many people.
Below is a photo of him without headgear, a still from the movie A Letter From Death Row. It would be easy for him to claim that he shaved his head for the role, so this is far from conclusive proof as to what lies beneath the bandana.
Norwood Rating : unknown, but based on his age (46) I'd guess a 4-5
