Latest uses of graphene: non-toxic hair dyes

Typically, hair dyes contain some harmful chemicals, such as ammonia. These are used to “pry open” the overlapping scales that make up the epidermis of each hair. Once these scales are opened, the coloring molecules from the dye can enter the hair and chemically alter it, thereby changing its color. Needless to say, this process will definitely affect the quality of the hair. Colorant molecules can also be toxic; because they are small, they may penetrate the skin and enter the body, causing adverse reactions. On the other hand, graphene is non-toxic and chemically inert. The dye created by researchers at Northwestern University contains tiny sheets of graphene that wrap around each hair strand, forming a uniform coating that gives the hairs their natural graphene-colored appearance. The non-toxic polymer binder in the dye allows these graphene materials to stick to the hair, enabling them to withstand at least 30 washes without color fading. Graphene sheets are not only non-toxic, but also cannot penetrate the skin because they are much larger than the coloring molecules used in conventional hair dyes. Furthermore, due to graphene’s antistatic properties, the dye should be able to prevent static electricity from building up in the hair. It is reported that the process of applying hair dye to the hair and letting it dry takes less than 10 minutes. The hair dye uses the commonly available and inexpensive graphene oxide, so its cost is not high. “People can use this hair dye to make the surface of their hair conductive,” said Professor Huang Jiaxing. “Then, it can be integrated with wearable electronic devices or serve as a conductive probe – our only limitation is our imagination. ” The paper on this research was recently published in the journal Chem.
