Justin Bieber sports rather terrifying platinum blond hair on ‘Today’ show

Justin Bieber’s been saying he’s learned now how to make better decisions.

But ... look at that hair.

The singer’s long-over-short ‘do practically glowed platinum blond during his Thursday morning concert appearance on the “Today” show. Just look it. Look at it.

Look. At. It.

“I do see some resemblance to my former hairstyle,” Kate Gosselin, she of the infamous hedgehog hairstyle, told Cosmopolitan.com after seeing Bieber’s previously less platinum incarnation on the MTV Video Music Awards at the end of last month. “Justin’s is a current take on it, yes! And it’s OK. He can have it!”

She thought its easy-care nature might mean less time spent focusing on his hair and more time focusing on his music.

But now that it’s platinum, all we can focus on is his hair.

However, all that peroxide may have made him a bit cranky on Thursday. As the show was going to commercial, the Biebs was caught snapping at a cameraman for coming too close to him while he was dancing.

“Next time I won’t dance because the camera’s here the whole time. Might as well not dance,” he said crankily but calmly. But then his voice got tense. Whiny, actually: “What do I do this for if they’re just gonna ...”

And then it went to commercial. Dang.

You do it because it’s your comeback, Justin. And because now you’re the youngest guy ever to debut at No. 1 on Billboard’s Hot 100.

Bieber’s time off stage seems to have left him a little bit rusty. After his touted return at the MTV Video Music Awards, he cried on stage, then explained on “The Tonight Show” the next night that he’d been overwhelmed by the audience’s support. He also revealed that he’d “missed some cues” and was a little disappointed.

One thing that didn’t disappoint during the “Today” concert: In addition to his newer music, including the new tune “What Do You Mean?,” Bieber did an acoustic rendition of his first hit, “Baby.” Now that’s a decision we — and everyone in the audience who sang along in the rain — can stand behind.

Just keep the ballcap on, baby.
