For as much time as is spent trying to figure out what’s inside President Trump’s head, what’s on top of it has attracted less significant scrutiny but a fair bit of curiosity.

On Friday, he lifted the veil. So to speak.

Appearing at the Conservative Political Action Conference in Oxon Hill, Md., the president poked fun at his own mop, a tangle of twists and turns that coalesce in what, in the end, becomes an apparent full head of hair.

But if you look within, the president said, not all is as it seems. As Mr. Trump was speaking, a television monitor, showing him on the stage, caught his eye.

“What a nice picture that is,” he said. “Look at that. I’d love to watch that guy speak.”

The crowd roared. Then, as many people would do when they suddenly realize they’re being looked at, he considered how his hair looked. He hovered his hands over his multi-angled locks, turned his back to the crowd to show off his solid-gold covering like a tarp keeping the rain out, then briefly touched the edges over his neck.
