Leah: There's nothing more traumatizing than finding your first gray hair.

Noah: It's a sure sign that we're getting older. Or is it?

Leah: Actually, it is.

Noah: Yeah, we were just trying to put a positive spin on it.

Leah: Each strand of hair has two parts, the shaft, that's what we see, and the roots, which is anchored under the scalp.

Noah: A follicle, a tube of tissue under the skin surrounds each root. Every hair follicle contains pigment cells that continuously produce a chemical called melanin.

Leah: And melanin gives the growing shaft of hair it's color.

Noah: As we age, the follicles pigment cells gradually die off, just like our hopes and dreams.

Leah: Wait. What?

Noah: Just keeping it real. Anyway the fewer pigment cells in a follicle, the strand of hair no longer contains as much melanin, becoming a more transparent color as it grows, like gray, silver, or white.

Leah: So basically, gray hair is just a part of the aging process.

Noah: Nature's way of signaling to the world that our best years are behind us.

Leah: Wait. That is not what it signals. It signals wisdom and experience.

Noah: Really? Would you let your hair go gray?

Leah: Never. Never, ever.

Noah: Yeah. I didn't think so. I think you actually have a little gray right there.

Leah: I do? Wait. Where?

Noah: Everywhere.

Leah: No. He's just kidding. Get it. Get it out now.
