Scientists may have finally figured out why hair turns gray — and how to stop it

By Alex Mitchell
April 21, 2023

They’ve got this one on locks.

Researchers at NYU have unlocked fresh evidence as to why human hair loses its natural color over time — which could help prevent people from graying.

The new study, conducted using mice and published in Nature, a peer- reviewed journal, closely examined the melanocyte stem cells (McSCs) known to control hair color.

Earlier in life, these cells can be remarkably dynamic, but with age, as hair is lost and regrown, the McSCs tend to slow down, getting trapped in what’s known as the hair follicle bulge, meaning they don’t get a chance to finish the job they were created to do.

Finding a way to get them moving again, which appears to be entirely possible, could mean the end of gray hair — not just in mice, but in people too, according to the team at NYU’s Grossman School of Medicine.

“[This] adds to our basic understanding of how melanocyte stem cells work to color hair,” said study lead Qi Sun, PhD, a postdoctoral fellow at NYU Langone Health. “The newfound mechanisms raise the possibility that the same fixed positioning of melanocyte stem cells may exist in humans,”

My paternal grandfather always told me he had so much on his chin, and so little up top, because he kept tugging at his beard.

I'm not sure how good I would look with hair my natural color and all these wrinkles on my face. At least I match. :rolling: :rolling:

Not only the migration, the gray hair on my chin is so thick and strong it is like cutting a wire brush. In fact it doesn't actually 'cut' when I hit it with a trimmer, it sort of shatters and flies all over the place like a wire brush would do.

If they kill their own with no conscience, there is nothing to stop them from killing you.

No, but they've apparently found a way to dramatically decrease the annual income of hair dressers around the world, so they've got that going for them.

I had to chuckle at this one.  The least of my worries is my hair turning gray.  I could care less.

Mine is a mix of gray, white on the sides, and a little brown on the back. So maybe science can find a way to stop my multi colored hair

On the plus side I have very thick hair that’s stubbornly determined to stay thick even as I age and it changes color

I just wish it would hurry up and pick just one color

I work with a woman who is in her 40s that’s got long graying hair and she is drop dead gorgeous. And I worked with two now retired nurses that had gray hair, but were pretty foxy

I guess there are worse things than gray hair

I'm kinda thinking enough with the beard trimming, gonna go all Santa Clause and when my doctor says something about my weight I will say sorry I'm a method actor and have to get in character.

I've earned my grey hairs.  I'm keeping them as trophies for living this long.

Too many of my school classmates have been taken from this life way too young.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
