Grey hair is mostly caused by genetics, and often there’s nothing to do to prevent or fix it, but there are cases when grey hair is caused by bad nutrition or stress. In these cases, it is possible to reverse the process.
Low levels of Vitamin B12 can cause thinning, dry, and greying hair (not to mention a handful of other health problems like constant fatigue and lack of concentration). Keep your levels of the vitamin B12 in a healthy range by consuming lots of eggs, poultry, milk products, and seafood.
While there’s really nothing to do to prevent or reverse greying of our precious hair strains, there’s a simple thing to do – besides eating foods rich in vitamin B12. Research has shown that low levels of pantothenic acid in mice turned them grey. The study was conducted by the Linus Pauling Institute.
If our greys are due to stress, the grey may be reversed naturally, as well as with a bunch of other treatments. In response to stress, hormones can deplete the melanocyte stem cells that determine the color of our hair. Research has found that stress indeed causes the stem cells to leave hair follicles, making hair white or grey.
