A new study has explained the reason why our hair turns grey. Though the greying of hair is usually associated with aging, it can also be caused due to genetics and heredity.
According to a research done by the Journal of the Federation of American Societies for Experimental Biology, hair cells naturally produce small amounts of hydrogen peroxide, an anti bacterial chemical which is also commonly used in the medical field for the cleansing of open wounds prior to application of medication.
The research further noted, that it is the enzyme that breaks the hydrogen peroxide before it can effect the greying of our hair; but as we get older, our system makes less of the enzymes, so the hydrogen peroxide can build up to pigment altering levels thus affecting our colored black hair into grey.
Antioxidants can neutralize hydrogen peroxide. Until now, scientists are studying possible treatments to show down the process of greying. However, it can be said that up to this time, there is no practical way to get rid of them except dyeing our hair.
Many believed that if you plucked one grey hair, two will grow back. The pigment formation in one follicle has no influence over the other.
As we get old, the pigment cells in our hair follicles either die off or lose the ability to make and transfer colors to the hair shafts. Besides , it is also believed to be genetics.
