<pre>Scientists have developed a hair dye based on graphene

Technologies of the future miraculously penetrate into different spheres of our life. For example, at the University of Illinois, the team of Professor Jiaxing Huang created a hair dye, in which the working substance is graphene. Miracle paint is not toxic, resistant to flushing, quickly applied, cheaper than usual and also serves as an energy platform for portable electronics.

A typical hair dye contains a chemically aggressive substance, like ammonia, which destroys and opens scales of the cuticle – the protective layer of the hair. Then the active ingredients penetrate inside and change the color of the hair, in fact, poisoning it. Particles of toxins are very small and can seep into the blood, but even if the risk is minimal, in any case, the hair is severely affected by this effect.

Graphene has a thickness of only one atom, but is represented by extensive fragments of the film, which simply wraps around the hair. It remains to add glue and coloring polymers, and get a coating that does not harm the hair. And it's so strong that after 30 sessions of washing the head with shampoo it does not disappear anywhere. One trouble – the choice of shades is limited between black and brown.

Thin, but large graphene films do not penetrate the skin, they are non-toxic and have antistatic properties. If you take a substandard, rejected graphene oxide, you get a very cheap material, akin to coal dust. The process of staining is reduced to spraying the mixture and drying, maximum 10 minutes at all. And, in addition, the hair becomes the conductor of an electric current – you can attach a hair clip-gadget and feed it without any wires, straight through the hair.
