Researchers develop hair dye using graphene, according to a report published on March 19, 2018.
This new alternative to toxic and damaging hair dyes was developed by researchers at Northwestern University. Harsh chemicals such as bleach and ammonia used in commercial dyes is the reason for the damage of hair. It also contains molecules that are toxic, which can go deep into the skin.
The graphene-based hair dye is non-toxic and lasts through 30 washes without fading. Graphene is 200 times stronger than steel and is conductive as well. Professor Jiaxing Huang, who led the study said, “This is an idea that was inspired by curiosity. It was very fun to do, but it didn’t sound very big and noble when we started working on it. However, after we deep-dived into studying hair dyes, we realized that, wow, this is actually not at all a small problem. And it’s one that graphene could really help to solve.”
As graphene-based dyes are dark colored, it will work well for people going from blonde to brunette. The new dye was tested on many blonde hair samples. Natural geometry of graphene sheets were used by the researchers to bypass the harmful chemicals altogether. Unlike the available hair dyes, these sheets give an even coating to the hair as they are soft and flexible. Also, to ensure that the graphene sticks to the hair, researchers have integrated non-toxic polymer binders, which are edible.
Hair dyeing using this dye takes only 10 minutes. It has to be sprayed onto the hair and combed properly so that it is evenly coated on the hair. Then, blow drying the hair will complete the process of dyeing using graphene-based hair dye. This development will be a huge breakthrough in the field of dyes.
