Just to clarify, Borle didn't shave his head. His baldness is courtesy of a wig, and when he drops the disguise and becomes Wonka again his natural hair is back.
To give another example of how misguided this production is, let me describe the top of the show. The curtain goes up to reveal a little clock tower type structure. Borle walks out from behind it in top hat and waistcoat, but with his back to the audience. He then simply turns around and we see he is brushing his teeth. (It's completely bizarre star non-entrance; surely there are other ways give Wonka's first appearance more oomph.)
But, back to the teeth brushing...In between each brush and spit Wonka tries on different accents to decide what person he will be today. The first time we hear him speak it is in a thick, "redneck" type accent. At first I thought, good god, could this be the most misguided character choice in history to make Wonka a hillbilly? The audience was obviously confused too and the line was met with crickets. Then he tried on the next accent- the audience caught on to the joke set up- but that doesn't mean they laughed much this time either. He finally settles on his own voice and then sings Candy Man on an essentially empty stage.
I understand the impulse to let Borle do all this voices (well certainly not at the top of the show, but maybe later while on the factory tour) because this is the sort of zany, over the top shtick at which he so excels. The bit just isn't nearly funny enough to A) kick off the show or B) be our introduction to the beloved character. The larger dramaturgical issue is the question: for whom is Wonka trying on personas? He's a complete hermit, speaking (I presume) only to the Oompa Loompas and there's no need to be anyone but himself.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
