BRITISH scientists have identified the gene responsible for grey hairs and they are confident that it will be possible to produce drugs or cosmetics to switch it off.
Grey hair is a result of the depletion of melanin, which is responsible for the pigment in hair, skin and eyes.
It was already known that a gene called IRF4 played a crucial role in hair colour, but researchers at University College London have now linked it to lack of colour.
The finding could also ultimately make it possible to change hair or eye colour without using dyes. It could simply become a matter of taking an enzyme which changed the expression of the related genes.
