"It's just a normal thing," Us magazine quoted Zariff, who has been cutting Obama's hair for 14 years, as saying.
"It's not like he has a head full of gray hair. It's just a few gray hairs, so it's nothing to get excited about," the barber added.
Zariff further said that the color of the President-elect's hair "depends on the light, and then HD really brings it up a few more too."
He added: "When we see it, it looks very silvery and shiny. But of course when you see him in person, it doesn't look like that."
According to him, the stressful two-year campaign has not caused Obama to grow greyer.
He said even if the stress had some impact on the color of Obama's hair, it was "not as dramatically as it looks (on TV)."
Zariff said: "It's about normal for his age group. But I can't say that when he gets in the White House. We'll see."
There are chances that Zariff would follow Obama to Washington, D.C.
"I said, 'I'm going with you' (if you win)," Zariff told Obama, according to CBS 2.
"Absolutely. I'm not changing barbers, man," is what was Obama's reply.
