Graphene is something of a celebrity in the world of nanoscale materials. Isolated in 2004 by Nobel Prize winners Andre Geim and Konstantin Novoselov, these ultrathin sheets of carbon atoms are already finding novel uses in areas like electronics, high-efficiency heating systems, water purification technologies and even golf balls. According to recent research published in the journal Chem, hair dyes can now be added to this list.
But how safe and responsible is this new use of the carbon-based wonder-material?
Northwestern University’s press release proudly announced, “Graphene finds new application as nontoxic, anti-static hair dye.” The announcement spawned headlines like “Enough with the toxic hair dyes. We could use graphene instead,” and “’Miracle material’ graphene used to create the ultimate hair dye.”
From these headlines, you might be forgiven for getting the idea that the safety of graphene-based hair dyes is a done deal. Yet having studied the potential health and environmental impacts of engineered nanomaterials for more years than I care to remember, I find such overly optimistic pronouncements worrying – especially when they’re not backed up by clear evidence.

Probably would have a lot of issues with static electricity in your hair.
Of course I am being silly with posting. Yet being serious I have to wonder, “If the particles are so very small, could they seep into the skull.” And then from there on into the brain?! Attach a virus onto the nano particle and the next thing you know you have got brain disease. An interesting plot for a science fiction movie. Invasion of the shampoo monsters.
Worry about breathing particles which might enter the lungs, then possibly pass into the blood.
But graphene could make it superconducting, so there's that.
I would be more concerned about asbestos-like reactions with the mesothelium. I know graphite doesn’t cause problems (my dad had a pencil lead embedded in his arm since he was ten, and that never led to anything), but I’m curious about how the structure of graphene might promote a reaction.
It would also make your hair harder. Getting your hair cut would take diamond cutting tools.
Graphene is very different from graphite.
Snake oil.
Yes, I know. (See post #2)
Sounds like the next Tide Pod fad. I mean-what could go wrong?!?
They also once thought that bleeding you half to death was healthy!
We’ve advanced since then.
For some people, like the Irish who as a population are unusually predisposed to it, bleeding is still used if they have a usually hereditary condition called hemochromatosis, or “iron storage disease.”
We’ve advanced since then.
So they say today.
Not tomorrow!
It’s OK, it’s Organic.
And has no gluten....
It does temporarily reduce blood pressure. Other than that, all it does is fatigue you by forcing your body to produce more replacement blood.
Holy Moly.
How did he get he pencil lead embedded in his arm?
A girl hit me with her purse when I was about age 10 and I got the lead stuck deep into my right shoulder. While in the navy it worked its way out.
