An ingrown hair happens when a hair that's been cut, shaved, or tweezed curls and starts growing back into the skin, rather than away from it. Often, they'll go away on their own, according to the Mayo Clinic, but some ingrown hairs just keep growing and growing. 

YouTube is rife with videos showing the extraction of these seemingly infinite ingrowns. But one video rises above them all. It's called "The Longest Grossest Ingrown Hair In History." It was uploaded in 2012 and has been viewed more than 36 million times to date. It is the most-watched ingrown hair removal on YouTube, and — as of this writing — it even has more views than Dr. Pimple Popper's most popular video.

In the video description, uploader Joe Gross writes that his dermatologist initially thought that the dark bump on his face was a cyst.

When the video begins, he offers a bit of narration: "I've had this gigantic black mark on my face for months," he says, "and it looks like it's literally a pound of hair."

Watch him start pulling and you'll see exactly what he means. INSIDER can't verify that it's the longest ingrown hair in history (and it's highly unlikely that it weighs a pound), but it's still pretty unbelievable.
