How to lose 50 years of aging in 16 days
January 3, 2013
Gold nanoparticles darken white hair after treatment for one day, center, and 16 days, right (credit: American Chemical Society)
Attention seniors: French scientists have developed a process that permanently dyes white hair without harmful chemicals.
Philippe Walter and colleagues soaked white hairs in a solution containing fluorescent gold nanoparticles.
The hairs turned pale yellow and then darkened to a deep brown. The color remained even after repeated washings.
Using an electron microscope, the scientists confirmed that the particles were forming inside the hairs’ central core cortex.
The discovery has applications ranging from hair dyeing to electronic sensors to development of materials with improved properties, the scientists said.
The synthesis and detailed characterization of gold nanoparticles (AuNPs) inside human hair has been achieved by treatment of hair with HAuCl4 in alkaline medium. The AuNPs, which show a strong red fluorescence under blue light, are generated inside the fiber and are arranged in the cortex in a remarkably regular pattern of whorls based on concentric circles, like a fingerprint. It opens an area of genuine nanocomposites with novel properties due to AuNPs inside the hair shaft. (Credit: American Chemical Society)

In the future, some people will live forever?
by Bri
Many people believe that technology will let us live indefinitely.
by Mr.X
Many?Really? I guess the vast majority of people don’t believe something like that.
There are more people who believe that they alreade live forever (not only indefinitely), thanks to some magic fairyman.

ALEXEL,
While I am not sure how to spell it, I am pretty sure white hair at a young age is due to your not having sufficent “selenium” in your body. And IF you will spend some time looking in to this, I am sure youy can find more information on this.
I hope this helps.

Hey Fellow Seniors.
Fifteen years ago, when I was only 62 years old, I started drinking, and when needed, using topically, the ONLY thing this Agnostic Atheist Activist has
ever repeatedly called a “MIRACLE”! And while I call it a miracle for many reasons, here are the ones I am referring to now.
Within a day of my starting to drink the juice from a fruit grown all around the world in the tropics and used to effectivly treat and/or cure many thing for many thousands of years, not only THE ACHES AND PAINS OF OLD AGE DISAPPEAR, so did the sore muscles I got from playing Beach Vollyball. I’m now 78 and I STILL
do NOT suffer the aches and pains of old age OR have any sore Muscles!
SO, if YOU want to get rid of the aches and pains of old age as well as sore muscles and you also would like to INCREASE YOUR IMMUNE SYSTEM AND YOUR ENERGY OVER TWENTY PERCENT (as proven by clinial trails) THEN YOU SHOULD DRINK NONI JUICE.

Thanks for the advertisement, chum.

Does it remove the coarseness of most white/gray hair, too, or just change the color?

Fluorescent nanoparticles? Hmmm….I wonder how I’ll look
under a blacklight.

We’ve already had Grecian Formula for years so this is pretty minor news. Grecian Formula darkens the hair by bonding with the hair just as this does, with the added advantage of not turning the hair yellow in the interim.

Lighten up, the editor suggests…and sh’s right. I think this is a great development. Hair dyes are essentially toxic, so anything not containing PPD is a big step forward for those who want the freedom to look however they feel like looking. And for the uptight and self-righteous — keep your homely grey heads. Tant pis!

Well, that would work fine if I actually had hair left ;’)
Heck, I don’t have to comb it, I don’t have to wash it, I don’t have to get it cut. I’m just fine without.
by Derek
Hey, I’ll keep my silver hair over my previous boring brown hair. Much more dynamic!
by Bob Vasquez
I just knew that this one would get lots of responses (including mine). How about just shaving your head?

‘King Midas asked that anything he touched would be turned to gold. Dionysus granted his wish but warned him about his greed. Midas was very happy. He touched a tree and it turned to gold. He touched the walls of his palace and it turned to gold. He touched his horse, then his servant, his food and finally his children. Everything turned to gold.’
I dunno if it’s so silly: it will hit public imagination and promote nanotech which will enable more funding. Hair and nails are different from the rest of the body, but we are a step closer to entering the body proper and correcting stiff like aging.
When A.i works with nanotechnology it’ll be formidable and fast.
We live in the twilight years of humankind.
When will the nanotech wave hit the knee of the curve anyone know?

I could say “lighten up” but that could be interpreted as a hair-coloring instruction :)
by Bri
In light of the article, I would suggest Zoe “dark” umor: sorry recent research shows that The Singularity won’t happen. Instead we are working on a simulated singularity. Hurry and buy some ” elixir of life” and watch those years disapear! Right before your eyes you’ll lose fifty years?( so you find them again.) For a limited time only, if you act NOW, we’ll through in a free bottle of Viagra! Satisfaction guaranteed!( just don’t ask for your money back)

Also I can do the same without expensive gold, just use the extract from crushed walnut/pecan green peelings
by Bri
Works great on wood. It’s how they stained things in colonial times.
by Deavman
It is not permanent since as the hair grows it reveals its original color….unless I am missing something.
by Alex
This is more of an alternate to hair dye than age reversal. You don’t get better health or less wrinkles through hair color.
by John Z
Haha, this is a really dumb invention. In the 16 days it takes for the process to be completed, the hair has already grown out so the person would have brown hair with white roots. And I agree with Kiwini. What a silly story.

Alexei, it’s probably genetics that is giving you the white hairs, just like long life in your relatives.

Looks like it has nothing to do with losing 50 years of aging. But the inaccurate title it got us to click, so mission accomplished. One positive is that this is yet another wonderful way to siphon disposable income from the silly. I’m all for that. Keep that economy moving.

Changing hair color is like putting a new coat of paint an old house, so WTF does this hair coloring process have to do with “losing 50 years of aging”?…
by asiwel
I think it is intended to be a joke. I used to tell my barber his haircuts took 10 years off apparent age … unfortunately, the best he seems able to do these days is only 5 years ….
by Betty
Alexei, I started greying at 15 years old. Don’t sweat it.

If your hair looses 50 years of age in 16 days what will happen?
Your hairs age will then be -25 years, perhaps you will be bald after the treatment?
by Alexei
I’m 25 years old and I already have partially white hair, what can it be? Otherwise I’m very youthful, I look like а 17-18 years old high school student, everybody were saying it to me, and all my grandparents lived between 86 and 90 and my Dad is 60 years old but he looks like he is 45 and he’s so physically strong and his blood tests are always 100% ideal (he is not a vegetarian, he doesn’t drink red wine and green tea or something like that), so I probably have very long telomeres but I still have many white hairs? How is that possible?
by Foye Lowe
Your forebears were greedy, Alexei, and kept it all . . . ; )
by Tom B.
Don’t worry so much.
by David
When I was your age all my friends use to joke at me and call me the old man because I was greying in High School…but now I’m 50 and I get to tease them…because I still have my grey hair and they are bald…just the caards your dealt
by Alexei
Well no one doesn’t joke at me and I don’t mind having white hair, I actually think it’s cool, I’m just afraid that it’s not a sign of something else, a more serious problem, I hope it’s not.
