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.
