A team of researchers at Northwestern University decided to use a different strategy: Instead of opening up the Hair, why not just coat it with tiny colored particles made out of graphene?
Graphene is basically a super-thin form of graphite — the same mineral as your pencil — where all the atoms lie next to each other in a single plane.
(“It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran-Wrap,” an engineer at Columbia said back in 2008 .)
This latest use of graphene in Hair Dye could be more of the same — but based on a study published this week in the journal Chem , it looks promising.
But it has been tested on disembodied samples of human hair, and the dye stayed put through dozens of washings.
Charged hair strands can “stand up on end, creating an uncomfortable ‘flyaway’ effect,” the study says.
