Is Bret Michaels Bald?

Happened to catch Rock of Love on VH1 earlier this morning and couldn't help but wonder if Bret Michaels of Poison fame is now bald. He's always seen with his head covered and blond locks flowing underneath a bandana, cowboy hat, or helmet. I've found pictures of him on the internet with a full head of hair back in the 80s 'big hair heyday'. Is he trying to hide something with all the head gear?
