Context: Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
Iron and copper
To avoid hair thinning and greying, iron and copper are one of the most essential nutrients. In fact, one independent anecdotal study proposed that sufficient levels of iron and copper may help in preventing early greying.
It might take 2 to 3 months or even a year to recover depending on the age. This is because after a certain age the scalp cells lose their renewal and absorbing abilities and also melanin production stops.
“Eumelanin production increases as we age, and as we age we tend to go grey. Therefore hair may get darker before the greys take over,” she explains.
As people get older, their hair often gets darker. According to IFLScience, this is due to changes in the production of melanin—the natural pigments responsible for hair, eye, and skin color. Two types of melanin are common: Eumelanin determines how dark your hair is, while pheomelanin controls how warm it is.
