Nano technology is opening up so many opportunities and the potential to make grey hair a thing of the past may just be a possibility with the latest discoveries.
A French scientist has found that hair could synthesise gold nanoparticles in to the cuticle.
Dr Philippe Walter was researching the keratin within the hair and used Gold nanoparticles to follow a substance during growth. Hairs absorbed the gold and turned pale yellow then a deep brown. This change of colour occurred deep within the central core cortex and stayed put even after washing.
These are just preliminary steps but it does open up the idea that with nanotechnology going grey may soon be a thing of the past.
