I remember Howie Mandel having bushy, curly hair. When did he go bald?
A long time ago, maybe. For years, though, he’s had a bushy curly hairpiece. The “natural” look is something I’ve seen him doing full-time only in the past few years.
Must be easier to get the glove over his head without the hair, eh?? 
He needs to lose that retarded po’ boy hat though.
Didn’t he stop doing that because he actually blew out his sinuses?
According to a recent interview, Mandel has a germ/dirt phobia. He washes his hands thoroughly and often. At one point, he decided that being bald was somehow cleaner. So, he shaved his head. His wife loved it. “You look so sexy!” “Umm, so what have I been for the past twenty years?”
Re Sinuses
Tremorviolet Is correct. At a performance, an audience member shouted “Do the gluuve thing!” After humorously mimicking their accent, Mandel explained why he no longer does the glove thing. One day, he had a severe headache and went to the doctor. The doctor discovered that Mandel had ruptured a sinus. He asked if Mandel knew how this might have happened. “Well, I sometimes slip a surgical glove over the top of my head and inflate with my nostrils until the glove pops.”
“Why do you do that?”
“It’s part of my job.”
