When I look at Donald Trump, I think about one thing. No, not the gazillion dollars he has in the bank, or the impressive business empire he has built (and rebuilt) over the years.

It’s his hair.

I’ve never been able to understand why, with his virtually unlimited resources, he doesn’t do anything about that nasty mop?!

Sure, it’s as much his signature as the “You’re Fired” comments he tosses around with such abandon on “Apprentice.” It’s unattractive to say the least, and more than a little unsettling.

Apparently I’m not the only one critical of The Donald’s coiffure. It looks like Oprah Winfrey has set her sights on it as well. According to the New York Post, the “Queen of Daytime” has extended the presidential hopeful an invitation to appear on one of the final episodes of her show. For a makeover, no less!

Sources say the show’s producers have vowed to treat the occasion with the “integrity” deserves and not let it devolve into “a joke.”

Killjoys.

No word if Trump, who appeared on “Oprah” in February, has accepted the invitation.
